Product FAQs
5 answersWhat panels accept the ITE E22B050 circuit breaker?
The E22B050 is designed for ITE and Siemens panelboards that are configured for E-frame or E2-frame bolt-on breakers. Check your panel wiring diagram to confirm compatibility with E2 frame types.
Are ITE and Siemens E22B050 breakers interchangeable?
Yes. Siemens purchased the ITE brand and continues to produce this exact model. A Siemens E22B050 is the direct replacement for an original ITE E22B050, maintaining the same E2 frame size and bolt-on mounting.
What is the advantage of the bolt-on connection on the E22B050?
The bolt-on mounting secures the breaker directly to the panel bus bars with screws. This creates a highly reliable, vibration-resistant electrical connection that is typically required in commercial and industrial panelboards.
How does the thermal-magnetic trip mechanism work on this breaker?
The E22B050 uses a bimetallic strip for long-time thermal protection against sustained overloads, and an electromagnetic coil for instantaneous protection against severe short circuits. This dual-function design ensures comprehensive circuit protection.
Can the E22B050 be used in systems with high fault currents?
This breaker has an interrupting rating of 10kAIC at 240V. It must only be installed in systems where the available fault current does not exceed 10,000 amps. For systems with higher available fault currents, a breaker with a higher AIC rating is required.
