Product FAQs

6 answers
Which panelboards are compatible with the E22B100 circuit breaker?

This E-frame breaker is designed for bolt-on installation in Siemens P1, P2, and P3 panelboards, as well as SB switchboards and legacy ITE panelboards.

What wire sizes are accepted by the E22B100 lugs?

The included lugs accept wire gauges from 10 AWG up to 1/0 AWG and are rated for use with both copper (Cu) and aluminum (Al) conductors.

Does the E22B100 support DC voltage applications?

Yes, alongside its standard 240V AC rating, this thermal-magnetic breaker is fully rated for 250V DC systems, providing a 10kA interrupting capacity for both current types.

Is the Siemens E22B100 the same as the ITE E22B100?

Yes. Siemens acquired ITE and continued manufacturing the E-frame series under the same catalog numbers. A modern Siemens E22B100 is a direct, code-compliant replacement for a legacy ITE E22B100.

How does the E22B100 mount into the panel?

It utilizes a bolt-on connection to secure directly to the panelboard bus, ensuring a high-reliability contact suitable for commercial and industrial loads.

Are the trip settings adjustable on the E22B100?

No, this breaker features a fixed thermal and fixed magnetic trip unit. Both the long-time and instantaneous (LI) trip functions are factory set and cannot be adjusted in the field.
