Rated 65 kAIC at 480VAC, this 2-pole, 30A molded case circuit breaker provides robust thermal magnetic protection for commercial distribution. The Siemens HHED62B030 is part of the Sentron ED frame lineup, featuring fixed LI trip functions. It mounts into Siemens Sentron P1, P2, and P3 panelboards using a bolt-on connection. This model is replaced by the 3VA5130-6EC21-0AA0, which requires a mounting kit for proper panelboard integration.

Product FAQs
8 answers
Which panelboards are compatible with the Siemens HHED62B030?
This bolt-on breaker is designed for use in Siemens Sentron Series panelboards, specifically the P1, P2, and P3 models. It is also compatible with properly configured Siemens switchboards and standalone enclosures.
How does the HHED62B030 differ from the ED62B030 or HED62B030?
The prefix indicates the interrupting capacity at 480VAC. The standard ED62B030 is rated at 18kAIC, the HED62B030 at 42kAIC, and the HHED62B030 offers the highest rating in this standard frame size at 65kAIC. All three share the same physical dimensions and mounting style.
What wire sizes are accepted by the standard lugs on this breaker?
The factory-installed lugs accept wire gauges from 10 AWG up to 1/0 AWG. The terminals are rated for both copper (Cu) and aluminum (Al) conductors.
Is the HHED62B030 rated for direct current (DC) systems?
Yes, this thermal-magnetic breaker is rated for use in DC applications up to 250VDC, providing an interrupting capacity of 30kAIC at that voltage.
Does this breaker provide equipment ground fault protection?
No, the HHED62B030 features a standard thermal-magnetic trip unit with long-time and instantaneous (LI) functions only. It does not include ground fault or arc fault protection circuitry.
Can the trip settings on the HHED62B030 be adjusted in the field?
No, this specific Sentron ED frame breaker features fixed thermal and fixed magnetic trip elements. The trip curve cannot be adjusted by the user.
Will this breaker fit in older I-T-E panelboards?
Siemens Sentron ED frame breakers are often used as direct replacements in legacy I-T-E panelboards that specify ED4, ED6, HED4, or HED6 frame breakers. You must verify the specific panelboard labeling to ensure the HHED frame is an approved replacement for your exact system.
What is the maximum interrupting rating for this breaker at 240VAC?
While it is rated for 65kAIC at 480VAC, the interrupting capacity increases to 100kAIC when applied to a 240VAC system.
