Product FAQs
5 answersWhich panelboards are compatible with the Siemens HED41B045?
This ED-frame breaker is designed for use in Siemens Sentron panelboards, including the P1, P2, P3, P4, and P5 series, as well as Siemens SB switchboards.
Can the Siemens HED41B045 replace older ITE or Gould breakers?
Yes. Siemens acquired the ITE and Gould electrical distribution lines. The current Siemens HED41B045 is a direct, exact replacement for legacy ITE and Gould HED41B045 breakers.
What does the 'H' in the HED41B045 catalog number indicate?
The 'H' designates it as a high-interrupting capacity version of the standard ED4 frame. While the standard ED4 frame is rated for 18kAIC at 277VAC, the HED4 frame provides a higher 25kAIC rating at 277VAC.

As a 1-pole ED-frame molded case circuit breaker, it requires 1 inch of unit mounting space in the panelboard.

Yes. Standard thermal-magnetic ED-frame breakers like the HED41B045 are suitable for reverse feed applications.
