Siemens B215GFH GFCI Molded Case Circuit Breaker

Select the Siemens B215GFH for single-phase applications within its 120/240VAC rating. Its 2-pole construction switches and protects two circuit conductors.

The 22kAIC rating describes the breaker's ability to interrupt fault current. Available fault current at the installation point must not exceed this rating.

GFCI protection monitors current imbalance to detect ground faults and interrupt the circuit. Choose this feature when the circuit requires ground-fault protection in addition to overcurrent protection.

Connect the pigtail neutral to the system neutral as part of the GFCI installation. This neutral connection supports operation of the ground-fault protection.

This breaker uses bolt-on mounting, so installation requires securing it with bolts. Plan the installation around this fastening method.

Conductors terminate in lugs, which clamp the conductors to make the electrical connection. Prepare and secure each conductor for lug termination during installation.

The thermal element provides long-time overload protection, allowing a delayed response to sustained overcurrent. The magnetic element provides instantaneous response to high short-circuit current.

The trip settings are fixed rather than field-adjustable. Select this breaker when its fixed protection characteristics meet the circuit's requirements, rather than planning to tune the trip settings after installation.

No. The 15A rating is the breaker's rated current, not an instantaneous trip threshold. Its thermal-magnetic trip responds to overloads over time and to short circuits rapidly, so distinguish rated current from trip behavior when evaluating the load.
