Product FAQs
6 answersWhat does the "L" suffix mean in the HED43B035L catalog number?
The "L" suffix indicates that the breaker comes factory-assembled with both line and load side lugs installed.
What type of mounting does the Siemens HED43B035L require?
This is a unit-mount, feed-thru circuit breaker. It is designed to be bolted directly into Siemens enclosures, switchboards, or motor control centers rather than plugging into a standard load center bus.
What wire sizes and materials are compatible with the terminals on this breaker?
The factory-installed lugs accept 10 AWG to 1/0 AWG wire and are rated for both copper (Cu) and aluminum (Al) conductors.
Can the HED43B035L be used in direct current (DC) systems?
Yes, in addition to its AC ratings, this breaker is rated for use in 250VDC systems with an interrupting capacity of 30kA.
What trip functions are included in the HED43B035L?
It features a non-interchangeable thermal-magnetic trip unit with fixed long-time and instantaneous (LI) trip functions. Both the thermal and magnetic trip settings are fixed and cannot be adjusted.
Is the HED43B035L interchangeable with standard plug-on breakers?
No, this is an ED-frame molded case circuit breaker designed for unit mounting in industrial switchboards and motor control centers. It will not fit in standard residential plug-on load centers.
