Description

Part of the Type BLE family, the Siemens BE120 provides 30mA ground fault equipment protection (GFEP) for 20-amp commercial circuits. It is calibrated to prevent equipment damage from line-to-ground faults, distinguishing it from 5mA personnel GFCI devices. This bolt-on MCCB installs into Siemens P1, P2, and P3 panelboards, ensuring a rigid power connection. It substitutes the legacy B120EG. Featuring a 10 kAIC capacity, the breaker includes HACR and SWD ratings for switching duty.

Product FAQs

8 answers
What is the ground fault trip sensitivity of the Siemens BE120?

The BE120 features a 30mA ground fault trip threshold. This provides Ground Fault Equipment Protection (GFEP) to prevent equipment damage, distinguishing it from the 5mA threshold used in Class A GFCI breakers for personnel protection.

Which panelboards are compatible with the BE120 circuit breaker?

This bolt-on breaker is designed for installation in Siemens P1, P2, and P3 commercial panelboards. It is not compatible with standard residential plug-on load centers.

How is the neutral connection handled on the BE120?

The BE120 is equipped with a pigtail neutral wire. This pigtail must be connected directly to the neutral bus bar of the panelboard to power the internal ground fault sensing circuitry.

Does the BE120 replace any older Siemens or ITE breakers?

Yes, the BE120 serves as the direct replacement for the legacy Siemens B120EG equipment protection circuit breaker.

Can the BE120 be used to meet residential bathroom or kitchen GFCI code requirements?

No. The BE120 is a 30mA GFEP breaker intended strictly for equipment protection, such as heat trace cables. It does not provide the 5mA Class A personnel protection required by the NEC for residential wet locations.

What wire sizes are accepted by the load lugs on the BE120?

The load side lugs accept 14 to 10 AWG copper conductors, or 12 to 10 AWG aluminum conductors.

What is the difference between the Siemens BL120 and BE120?

Both are 20A, 1-pole, bolt-on breakers for Siemens panelboards. However, the BE120 includes 30mA Ground Fault Equipment Protection (GFEP), whereas the BL120 is a standard thermal-magnetic breaker without ground fault sensing.

Is the BE120 part of the Siemens BLE family?

Yes, the BE120 is classified under the BLE type family, which designates Siemens bolt-on breakers equipped with ground fault equipment protection.
