Siemens ED22B025 Molded Case Circuit Breaker

The ED22B025 is designed for Siemens Sentron panelboards and switchboards. Because it is an ED frame breaker, it will fit standard depth enclosures specifically configured to accept bolt-on branch circuit breakers.

Yes. Siemens acquired the ITE and Gould electrical distribution lines. The Siemens ED22B025 serves as a direct replacement for legacy ITE and Gould breakers with the exact same ED22B025 catalog number.

When applying this two-pole breaker on 250VDC systems, Siemens guidelines generally require wiring one pole on each leg of the direct current supply circuit to safely interrupt the fault current.

While ED2, ED4, and ED6 breakers share the same physical dimensions and mount in the same panel spaces, they differ in interrupting capacity. The ED2 series is rated for 10kAIC at 240VAC, whereas ED4 and ED6 models are built to handle higher fault currents up to 65kAIC.

It is a bolt-on breaker that fastens directly to the threaded bus tabs of a compatible Sentron panel using its integrated screws. This provides a secure, vibration-resistant connection preferred in commercial and industrial environments.

No. Siemens ED frame breakers in this size range are manufactured with fixed thermal-magnetic trip units. The trip mechanism is permanently sealed at the factory and cannot be removed or interchanged in the field.

No. The ED22B025 is a standard thermal-magnetic circuit breaker designed for basic overcurrent and short-circuit protection. It does not include GFCI or AFCI safety features.
