These modules can be replaced or upgraded without having to completely remove the wiring or enclosure.  The terminal block models allow easy connection using #10AWG to 2/0 wire.

 

Our Tier 450 series M2 Modular Terminal Block features the industry's most advanced metal oxide varistor (MOV) technology.

Its thermally protective, and arc extinguishing, design has a significant advantage when subjected to abnormal over-voltage and high fault current.

 

The multiple MOV technology allows for the continuation of protection even after a module failure (indicated by our dual color LEDs), giving critical time, under reduced protection, for a repair or replacement (This is covered by our 10 year warranty).

This makes these SPDs an ideal choice for any business that relies on microprocessor driven equipment.

 

This unit has a NEMA 4,12, & 13 rated steel enclosure with integrated mounting brackets, and is suitable for indoor and outdoor applications.

 

This modular SPD has models that range from 50kA to 150kA per mode.

 

You may select the UL 1449 location, Type 2 is the default, and most common selection. (If you are unsure of the UL 1449 selection you need, please contact us, we will be happy to help.)

 

All units come with form “C” remote contacts, two color LED indication, and an audible alarm. Surge counter is optional.
