Description

Built for commercial power distribution, the Siemens HED41B020 is a 1-pole, 20A molded case circuit breaker. It utilizes a reliable thermal magnetic trip unit to protect critical circuits against overloads. This ED frame breaker installs into Siemens Sentron panelboards and SB switchboards via a secure bolt-on connection. It is replaced by the 3VA5120-6EC11-0AA0, which requires a mounting strap kit. Delivering 100 kAIC at 120VAC, this HACR and SWD rated breaker handles demanding faults.

Product FAQs

7 answers
Which panelboards are compatible with the HED41B020 circuit breaker?

This breaker is designed for use in Siemens Sentron panelboards, including S1, S2, S3, S4, S5, and SE models, as well as SB1, SB2, and SB3 switchboards that accept ED frame bolt-on breakers.

Can I install this breaker in a standard residential load center?

No. The HED41B020 is a bolt-on molded case circuit breaker designed for commercial and industrial panelboards and switchboards. It will not fit in standard plug-on residential load centers.

Is the Siemens HED41B020 HACR rated?

Yes, this ED frame circuit breaker is HACR rated, making it suitable for overcurrent protection on heating, air conditioning, and refrigeration equipment circuits.

What does the "H" in the HED41B020 catalog number indicate?

The "H" designates this as a high-interrupting capacity breaker within the Siemens ED frame family. It provides a higher fault current rating than the standard ED4 series.

What is the difference between the ED41B020 and the HED41B020?

The difference is the short circuit interrupting rating. The standard ED41B020 is rated for 18kA at 277VAC, while the HED41B020 is the high-interrupting version rated for 65kA at 277VAC.

Can the HED41B020 be reverse fed?

Yes. Because this breaker features a non-interchangeable trip unit, it is suitable for reverse feed applications where power flows from the load side to the line side.

Does the HED41B020 provide ground fault or arc fault protection?

No. This is a standard thermal magnetic circuit breaker that provides overload and short-circuit protection. It does not include GFCI or AFCI functionality.
