UL high SCCR SPDs
UL Listed open Type 1 DIN-Rail 1-, 2-, 3- and 4-pole SPDs
The Bussmann™ series UL Listed open Type 1 surge protective devices feature a high 200 kA SCCR. Replaceable arrestor modules are mechanically coded with the base to ensure against installing an incorrect replacement. The unique module locking system fixes the module to the base, and allows it to be easily replaced without tools by simply depressing the release buttons.
These are new models that supersede the previous high SCCR SPD offering. Click this link to see the end-of-life and supersession notice.
Standard local visual status indication
The module’s visual indicator shows the protective status at a glance: green = good, red = replace.
Remote contact signaling
The standard three-pole terminal remote Form C contact signaling relay has a floating changeover contact for use as a break or make contact, according to circuit concept.
- Comprehensive High SCCR surge protection solutions for North American UL 508A applications
- Modular DIN-Rail design with module rejection feature makes it easy to identify, install and maintain
- easyID™ local visual indication and standard remote contact signaling make status monitoring simple
- IP20 finger-safe design improves electrical safety
The need for surge protection
Electronic products and devices are susceptible to damage from overvoltage surges, whether caused by switching inductive loads or lightning, overvoltage surges can quickly destroy sophisticated electronic packages used in industrial and commercial applications.
