Description
Part of the BL series, the Siemens BE250 provides 30mA ground fault equipment protection (GFEP) for commercial and industrial systems. Unlike standard 5mA personnel GFCI, this 50A breaker is calibrated to prevent nuisance tripping on equipment like heat trace cables and pumps. Designed for a secure fit, it bolts into Siemens P1, P2, and P3 panelboards. It is the legacy counterpart to the B250EG. This 2-pole thermal-magnetic breaker delivers a 10kAIC rating at 120/240VAC and is HACR rated.Specifications

Product FAQs
5 answersWhich panelboards accept the Siemens BE250 circuit breaker?
The BE250 is a bolt-on breaker designed specifically for installation in Siemens P1, P2, and P3 commercial panelboards.
What is the ground fault trip threshold for the BE250?
This breaker provides Ground Fault Equipment Protection (GFEP) with a 30mA trip sensitivity. It is calibrated to protect machinery and prevent nuisance tripping, rather than providing the 5mA personnel protection found in standard GFCI breakers.
How is the neutral wired on the BE250?
The breaker includes a pigtail neutral wire. This pigtail must be connected directly to the neutral bus bar in the panelboard to power the internal ground fault sensing circuitry.
What types of loads require a 30mA GFEP breaker?
A 30mA GFEP breaker is typically required for equipment protection applications such as outdoor heat tracing cables, snow melting systems, and industrial pumps where minor leakage current is normal.
What is the difference between the BE250 and a standard BLE frame breaker?
While both use the same physical BLE frame for bolt-on panelboard mounting, the BE prefix specifically designates this model as a Ground Fault Equipment Protection (GFEP) breaker with a 30mA trip level.
