Siemens B215EG GFEP Molded Case Circuit Breaker

This bolt-on breaker is designed for use in Siemens P1, P2, P3, P4, and P5 commercial panelboards.

The B215EG provides 30mA ground fault equipment protection (GFEP). This is designed to protect machinery from damaging line-to-ground fault currents, unlike standard 5mA Class A GFCI breakers used for personnel protection.

It features a white pigtail neutral wire that must be connected directly to the neutral bus bar in the panelboard to power the internal ground fault circuitry.

A load neutral is not required for straight 240V applications. However, the breaker's white pigtail must still be connected to the panel neutral bus for the ground fault sensor to function properly.

The B215 is a standard thermal-magnetic breaker. The B215EG adds 30mA ground fault equipment protection (GFEP) for specialized applications like heat tracing and snow melting equipment.

The Siemens QE215 is the plug-on equivalent. It offers the same 15A, 2-pole, 30mA GFEP protection but is designed for standard residential load centers rather than bolt-on commercial panelboards.

A 30mA GFEP breaker is used for equipment protection, such as heat tracing or snow melting systems. These applications often have higher natural leakage currents where a standard 5mA GFCI would experience nuisance tripping.
