Description

Providing reliable thermal-magnetic protection, this 20A Sentron series breaker is designed for industrial enclosures and motor control centers. The 3-pole unit features a durable ED frame construction to withstand harsh electrical environments. Unlike bolt-on models, this unit-mount MCCB includes factory-installed line and load lugs for flexible wiring in standalone applications. It is replaced by the 3VA5120-6EC31-0AA0 for newer installations requiring updated 600Y/347V ratings.

Product FAQs

6 answers
How does the Siemens HHED63B020L mount into a system?

The HHED63B020L is a unit-mount (feed-thru) circuit breaker. It is designed to be bolted directly to a mounting surface or bracket in switchboards, motor control centers, or standalone enclosures, rather than plugging onto a panelboard bus.

What does the HH in the HHED63B020L catalog number indicate?

The HH designates this as the extra-high interrupting capacity version of the Siemens ED frame. It provides a 100kAIC rating at 240V and 65kAIC at 480V, which is higher than standard ED4 or ED6 breakers.

Are lugs included with the HHED63B020L, and what wire sizes do they accept?

Yes, this breaker comes with factory-installed line and load lugs. The lugs accept 14-10 AWG copper wire or 12-10 AWG aluminum wire.

Can I use the HHED63B020L in a standard Siemens load center?

No, the HHED63B020L is an ED frame unit-mount breaker intended for industrial enclosures, switchboards, and motor control centers. It is not compatible with standard residential or commercial plug-in load centers.

Is the trip unit on the HHED63B020L adjustable?

No, this breaker features a non-interchangeable thermal-magnetic trip unit with fixed long-time and fixed instantaneous (LI) trip functions.

What is the direct replacement for the legacy HHED63B020L?

For newer installations or when replacing the HHED63B020L, Siemens recommends the 3VA5120-6EC31-0AA0 from the updated 3VA5 series, which offers equivalent 20A, 3-pole protection and Class H breaking capacity.
