Product FAQs
7 answersWhich panelboards are compatible with the Siemens HED42B080 circuit breaker?
This ED-frame breaker is designed for bolt-on installation in Siemens Sentron panelboards, including P1, P2, P3, P4, and P5 models. It is also compatible with Siemens SB switchboards and motor control centers.
Can the HED42B080 replace older I-T-E circuit breakers?
Yes, this Siemens breaker is a direct replacement for legacy I-T-E HED42B080 breakers. Siemens acquired the I-T-E product line and maintained the same physical dimensions and mounting hardware for the ED frame.
Is the HED42B080 suitable for direct current applications?
Yes, this thermal-magnetic breaker is rated for up to 250VDC with a 30kA interrupting capacity, making it suitable for specific DC control and distribution circuits.
What wire sizes are accepted by the load lugs on this 80A breaker?
The standard LN1E100 load lugs accept copper or aluminum wire ranging from 10 AWG to 1/0 AWG.
Can the Siemens HED42B080 be reverse fed?
Yes. Because this ED-frame breaker features a non-interchangeable trip unit and does not have Line and Load markings, it is UL listed for reverse feeding applications.
Is this breaker HACR rated for HVAC equipment?
Yes, the HED42B080 carries an HACR rating, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires this specific protection.
Does this breaker mount onto a standard DIN rail?
No, the HED42B080 is a bolt-on molded case circuit breaker designed specifically for panelboard chassis mounting. It does not natively mount to a DIN rail.
