Description
Designed for flexible installation, the Siemens HED41B030L is a 1-pole, 30A unit-mount molded case circuit breaker. It utilizes a thermal-magnetic trip unit to provide dependable long-time and instantaneous (LI) protection. Unlike bolt-on models, this breaker features line and load lugs (LN1E100), allowing it to mount into standalone enclosures and switchboards. It accepts 10 AWG to 1/0 AWG wire. This ED frame breaker boasts a 65kAIC rating at 277VAC and is fully HACR rated.Specifications

Product FAQs
6 answersWhat does "Unit Mount" or "Feed-Thru" mean for the HED41B030L?
A unit mount or feed-thru configuration means this breaker does not plug into or bolt onto a panelboard bus. Instead, it features lugs on both the line and load sides, allowing it to be individually mounted in an enclosure or switchboard and wired directly.
Which enclosures or panels are compatible with this ED-frame breaker?
This breaker is designed for use in Siemens Sentron series switchboards and individual enclosures that accept ED-frame unit mount breakers. It is not designed for standard load centers or panelboards that require plug-in or bolt-on bus connections.
How does the HED4 series differ from standard ED4 breakers?
The "H" in the HED4 prefix indicates a high interrupting rating. While standard ED4 breakers typically offer lower fault current ratings, the HED41B030L provides up to 65kAIC at 277VAC and 100kAIC at 120VAC for systems requiring higher short-circuit protection.
What does the "L" suffix in the HED41B030L catalog number indicate?
The "L" at the end of the part number signifies that the breaker comes factory-equipped with line and load side lugs. These terminals accept 10 AWG to 1/0 AWG copper or aluminum wire.
Is the HED41B030L suitable for direct current (DC) applications?
Yes, this thermal-magnetic breaker is rated for DC systems up to 125VDC, providing a 30kA interrupting capacity for direct current circuits.
What safety precautions are required when installing this feed-thru breaker?
Installation should only be performed by a qualified electrician. Ensure all power sources to the switchboard or enclosure are completely de-energized before mounting the breaker or terminating the line and load wiring.
