Additional Surge Protection Devices

AutomationDirect has extended its offering of surge protection devices to include Mersen’s Surge-Trap® Type 1 STXR series. With its small, compact design and line or load installation flexibility, the series is the perfect fit for branch panel and/or individual equipment protection.

The one-piece device requires no assembly and can be used at the machine or the main panel to protect equipment from downtime and/or damage associated with power spikes and surges.

Available in 120-600VAC models and a 200kA short-circuit current rating, these devices are ideal for use in ANSI/UL Type 1 or 2 SPD installations, such as AC distribution, power supplies, drive protection, fire alarms, control panels, and more.

Designed with industry-leading Mersen TPMOV® technology, the STXR series provides up to seven modes of protection. Additional features include an LED status indicator, ¾-inch knockouts with three-foot leads for easy installation, and a NEMA 4X enclosure for outdoor or indoor use; an optional mounting bracket is available for surface mount applications

Starting at $98.00, the STXR series surge protection devices are UL and CSA approved.
