The Bulletin 1492-MC Circuit Breakers with Ground Fault protection for Branch Circuits are available in 1- and 2-pole construction in 120/240V rating. Versions are available as Ground Fault Circuit Interrupters and as Ground Fault Equipment Protectors.
When protection from low-level fault currents for North American standards is required, two versions of protection are available.
- Circuit Breakers with protection for personnel use a threshold of 5 mA sensing to provide protection for people. These are typically know as Ground Fault Circuit Interrupters or GFCIs.
- Circuit Breakers that provide protection for equipment at a sensing threshold of 30 mA are also available. These are typically known as Ground Fault Equipment Protectors or GFEPs.
The following devices are tested and listed to meet the North American standards of UL 489, UL 943 (for GFCI), UL1053 (for GFEP), and CSA 22.2 No.5.1.
It is recommended that the devices be tested monthly by using the TEST button to check for proper operation of the device.
