Product FAQs
6 answersWhich Siemens panelboards are compatible with the HED41B050?
This bolt-on breaker is designed for use in Siemens P1, P2, and P3 panelboards, as well as SB switchboards. It mounts directly to the bus using a secure bolt-on connection.
Can I use the HED41B050 to replace a standard ED41B050 breaker?
Yes, the HED41B050 shares the exact same physical dimensions and ED frame footprint as the standard ED41B050. The HED4 version provides a higher interrupting rating (25kAIC at 277VAC compared to 22kAIC for the ED4), making it a safe, direct upgrade for systems requiring higher fault protection.
Is there a higher interrupting 1-pole ED frame breaker than the HED41B050?
No, the HED41B050 provides the highest interrupting rating available for a 1-pole Siemens ED frame breaker. The extra-high interrupting HHED6 breakers are only manufactured in 2-pole and 3-pole configurations.
Can the HED41B050 be reverse fed?
Yes, this breaker features a non-interchangeable trip unit and is UL listed for reverse feed applications. This allows power to flow from the OFF end toward the ON end, providing flexibility for specific panel configurations.
Is the HED41B050 HACR rated?
Yes, this breaker is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment.
Does this breaker have a trip-free mechanism?
Yes, it features a trip-free mechanism. This ensures the breaker will trip during an overcurrent or short circuit event even if the handle is physically held in the ON position.
