Product FAQs
7 answersHow should I size a circuit for the Siemens B220EGH?
The 20A rated current guides load and conductor sizing. Select it where a 20A circuit breaker meets the circuit's load requirements and applicable conductor protection rules.
What voltage and circuit configuration is this breaker rated for?
This two-pole breaker is rated for 120/240VAC, single-phase applications. Use those ratings when selecting protection for a circuit requiring two protected poles.
How does the 22kA interrupting rating affect selection?
The interrupting rating is 22kA at 120/240VAC. The available fault current at the installation point must not exceed that rating, so verify it when selecting the breaker.
What does GFEP protection do?
GFEP means ground-fault equipment protection. It helps protect equipment from ground faults and should be selected for that purpose rather than personnel ground-fault protection.
How does the thermal-magnetic trip operate, and can I adjust it?
The thermal element provides long-time overload protection, while the magnetic element provides instantaneous response to high fault currents. Both elements are fixed, so select the breaker for the circuit rather than planning to adjust its trip settings.
What does bolt-on mounting mean for installation?
Bolt-on mounting uses bolted attachment rather than plug-in engagement. Plan the installation around securing the bolted connection properly.
How are conductors connected to this breaker?
The terminal connections are lugs, which clamp the conductors at the breaker. Proper conductor preparation and secure lug termination are important for a reliable electrical connection.
