Engineered for commercial power distribution, the Siemens HHED63B050 is a 3-pole, 50A molded case circuit breaker from the Sentron ED frame series. It provides reliable thermal-magnetic protection with fixed LI trip functions. This bolt-on breaker installs into Siemens P1, P2, and P3 panelboards, as well as compatible switchboards. Rated for 65 kAIC at 480VAC, it handles demanding fault currents. This legacy ED frame model is replaced by the 3VA series, requiring a mounting kit for retrofits.

Product FAQs
7 answers
Which panelboards are compatible with the HHED63B050 circuit breaker?
This bolt-on ED frame breaker is designed for installation in Siemens P1, P2, and P3 panelboards, as well as compatible Siemens switchboards and motor control centers.
What wire sizes are accepted by the lugs on this breaker?
The factory-installed LN1E100 load lugs accept 10 AWG to 1/0 AWG copper or aluminum wire.
Can the HHED63B050 be used in direct current applications?
Yes, this thermal-magnetic breaker is rated for use in DC systems up to 250VDC, with a 30kA interrupting capacity at that voltage.
Is this ED frame breaker suitable for reverse feed applications?
Yes, Siemens ED frame circuit breakers with non-interchangeable trip units, including the HHED63B050, can be reverse fed.
Is the HHED63B050 HACR rated?
Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment group motor loads.
What is the difference between the HHED63B050 and other ED frame breakers like the ED63B050 or HED63B050?
The difference lies in the interrupting capacity. The HHED6 series features an extra-high interrupting rating, whereas standard ED6 and HED6 models have lower short-circuit ratings. They share the same physical dimensions and mounting.
What is the modern replacement for the legacy HHED63B050?
The legacy Sentron ED frame series is being replaced by the Siemens 3VA series. Upgrading to a 3VA breaker in an existing panelboard will require a specific retrofit mounting kit.
