Air Conditioners Added To Enclosure Cooling Options
Heat inside an enclosure can decrease life expectancy in controlling units such as PLCs, HMI, and AC drives. Excessive heat can cause nuisance faults from electrical and electronic components, circuit breakers and fuses. To help alleviate such problems, AutomationDirect has added NEMA-rated Stratus™ air conditioners for enclosures. These closed-loop cooling systems are recommended for harsh environments, or when there are washdown requirements, heavy dust and debris, or airborne chemicals present. Available in 120V and 230V units, the NEMA 12, 4 and 4X-frame Stratus 1,000 to 8,000 BTU/H air conditioners feature free-standing rigid chassis for easy installation and maintenance. NEMA 12 and 4 models are constructed of 16-gauge cold rolled steel; NEMA 4X units are made of 16-gauge 304 stainless steel. All units contain an active condensate management system; NEMA 4 and 4X models have protective-coated condenser coils. Designed to fit enclosures as shallow as 12 inches, each unit features a digital LED temperature controller with visible alarm and is pre-wired for external alarm monitoring. The highly energy-efficient compressors are charged with CFC-free refrigerant and equipped with anti short-cycle protection. All models are UL and cUL listed. Replacement filters are also available for each of the three frame sizes. To see the full line of Stratus enclosure air conditioners, visit: www.automationdirect.com/enclosure-cooling
Single-Piece Flexible Wire Duct Now Available
AutomationDirect’s Dinosaur self-adhesive flexible wire duct is designed for transporting wiring to cabinet doors from control panel interiors and for electronic equipment. Sizes ranging from 0.5 x 0.5 inch to 1.5 x 1.5 inch are now available in single-piece quantities or cost-saving cartons. With a UL 94V-0 flammability rating and CSA approval, the duct is made of low-smoke, halogen-free polypropylene, giving it resiliency to bend and twist without breaking. The flexible duct can be used in extreme operating conditions up to 176°F℉. Base perforation on the self-adhesive duct allows for mounting with rivets or on DIN rail, if desired.

ProSense™ Line Adds Quarter-Inch Temperature Probes
AutomationDirect’s ProSense line of process sensors now includes quarter-inch RTD temperature probes. The three-wire, 100 ohm platinum RTD probes are made of durable 316 stainless steel and measure temperatures ranging from -40 to 302°F. The probes are available in lengths from 160mm to 360mm. Thermowells and fittings are also available. To see the complete proSense line, visit: www.automationdirect.com/temp-sensors
Select DINnector Products Available In Smaller Quantities
In keeping with our objective to provide the best value in industrial control products, AutomationDirect now offers a selection of popular terminal-block mounted supplementary protectors, ground terminal blocks, end brackets, and DIN rail in smaller quantities. DINnector resettable supplementary protectors are now available in single-piece and 20 packs. A selection of screw-type terminal block sockets for the protectors, with and without LED indicators, can now be purchased in both five-packs and 50-pack quantities. Terminal block spacers and separators are available in 10-packs and 50-packs. Ground terminal blocks rated for size six to 10 AWG wire are available in quantities of 10 and 50. DIN rail can now be purchased in packs of two as well as boxes of 10. End brackets are also available in 10-packs and 50-packs.

UL 489 Miniature Circuit Breakers Now Available
The Eaton WMZT series miniature circuit breakers have been added to AutomationDirect’s product offering of circuit protection devices. The single-pole, double-pole and triple-pole devices, available in sizes from 0.5 – 40 Amps, offer optimum and efficient protection for branch and control circuits. The series’ current-limiting design provides fast short circuit interruption, within one half cycle of the fault, which reduces circuit-damaging let-through energy. WMZT circuit breakers are available with C and D curve thermal magnetic overcurrent protection characteristics. C-curve devices are suitable for applications where medium levels of inrush current are expected, such as small transformers, lighting, pilot devices and control circuits. D-curve devices provide protection from nuisance tripping where high levels of inrush current are expected, such as motors, transformers and power supplies. The series is also suitable for reverse-feed applications. The series is DIN-rail mountable and features a trip-free design so the breaker cannot be defeated by holding the handle in the “ON” position. A selection of field-mountable accessories is also available, including auxiliary and alarm switches, shunt trip, lockout attachments and bus bar systems.

MCCB Door Safety Hardware Added
AutomationDirect now offers Type C361 door interlocking safety handle and roller kits for the 3P Series molded case circuit breakers. The safety interlock handles, when connected to the MCCB, secure an SDN series NEMA 12 disconnect enclosure to protect against unauthorized entry while the breaker is in the ON position. A door interlocking safety roller kit is available for enclosures over 36″ tall. View the molded case circuit breakers and accessories at: https://www.automationdirect.com/mccb
Manual Motor Controllers/Disconnects
The new Bryant® line of manual motor controllers (MMC) is UL listed as “suitable as motor disconnects.”
Because the NEC® recognizes that a controller and disconnect can be the same unit (article 430.109), Bryant has designed a compact controller to meet the rigorous demands of a motor disconnect. By utilizing Bryant’s MMC devices, the user benefits from the convenience of one device fulfilling two needs.
Bryant’s controllers feature thermoset bodies, to provide high resistance to electrical arc tracking, and AC-rated silver alloy contacts for excellent conductivity and extended life. The compact devices are available oin NEMA 1, 3/3R and 4X enclosures; each enclosure has lockout/tag out capability.
Bryant Toggle AC manual motor controllers feature quick-make/slow break operation to provide reliability and long life. Each toggle switch controller has a 10,000 amp high-fault short circuit withstand rating, excellent dimensional stability and superior dielectric strength. Optional NEMA 1 enclosures without switches, as well as side guards for close wall applications and finger-safe environments, are also available.
Single-phase and three-phase toggle controllers are available in 30, 40 and 60 Amp sizes, up to 600 VAC, and 2-pole and 3-pole configurations.
Available enclosed toggle AC manual motor controllers feature NEMA 1 or NEMA 3R enclosures. NEMA 1 metal enclosed switch controllers, ideal for use in indoor environments, are designed with ½” and ¾”-inch NPT wiring conduit knockouts. The all-aluminum cover and base are designed with top, bottom or back wire entry points; the base is pre-drilled for rear surface mounting.
NEMA 3R rain-tight enclosed toggle controllers are available in either all-aluminum or chemical and impact resistant thermoplastic enclosures, making them ideal for outdoor applications. The all-aluminum enclosure, with pre-drilled base for rear surface mounting, is designed with ½” NPT wiring knockouts for 30 Amp models; 60 Amp models feature ¾” and 1″ conduit knockouts.
NEMA 4X enclosed rotary AC manual motor controllers, ideal for heavy wash down and corrosive environments, feature impact and chemical resistant thermoplastic enclosure bodies. An over-center rotary switching mechanism ensures reliable operation and allows positioning of up to two N.O. / N.C. auxiliary contacts.
