Product FAQs

5 answers
What is the difference between Siemens ED4 and HED4 circuit breakers?

The HED4 is the high-interrupting version of the standard ED4 frame. While a standard ED4 3-pole breaker has a standard interrupting capacity, the HED43B035 provides a higher interrupting rating of 42kAIC at 480VAC.

Can the HED43B035 be reverse fed?

Yes, Siemens ED frame thermal magnetic circuit breakers, including the HED43B035, can be reverse connected. They are not restricted by line and load markings.

What are the standard lug and wire size specifications for this breaker?

The HED43B035 comes standard with load lugs (catalog number LN1E100) that accept 10 AWG to 1/0 AWG copper or aluminum wire.

Is this breaker compatible with standard DIN rail mounting?

No, the HED43B035 is a bolt-on circuit breaker designed specifically for Siemens Sentron panelboards, SB switchboards, and motor control centers. It does not mount to a DIN rail.

Is the HED43B035 HACR rated?

Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment.
