Description
Built for industrial applications, the HHED62B045L is a 2-pole, 45A molded case circuit breaker from Siemens. It provides reliable long-time and instantaneous (LI) thermal-magnetic trip protection for demanding electrical systems. This unit-mount breaker installs into standard enclosures and motor control centers. It includes both line and load lugs (indicated by the 'L' suffix) and is replaced by the 3VA5145-6EC21-0AA0. As an HHED6 type, it offers extra high interrupting capacity.Specifications

Product FAQs
6 answersWhat panels and enclosures accept the HHED62B045L?
This ED-frame breaker is designed for use in Siemens Sentron panelboards, switchboards, and motor control centers (MCCs) that accommodate unit-mount, feed-thru breakers.
What does the "L" suffix in the HHED62B045L catalog number mean?
The "L" suffix indicates that the breaker is factory-supplied with both line and load side lugs installed. Standard Siemens ED-frame breakers without this suffix typically include load side lugs only.
How does the HHED6 series compare to ED4, ED6, and HED4 breakers?
All of these models belong to the Siemens ED-frame family and share the same physical footprint. The difference lies in their interrupting ratings, with the HHED6 series offering the highest capacity (65kA at 480VAC) among these options.
Can the HHED62B045L be reverse fed?
Yes, standard Siemens ED-frame thermal-magnetic circuit breakers are suitable for reverse feed applications, as they are not restricted by "Line" and "Load" markings.
How should this 2-pole breaker be wired for 250VDC applications?
When applying this breaker on 250VDC systems, Siemens generally recommends wiring one pole on each leg of the direct current supply circuit. It provides a 30kA interrupting rating at 250VDC.
Are the trip settings on this breaker adjustable?
No, the HHED62B045L features a fixed thermal and fixed magnetic trip unit. The long-time (L) and instantaneous (I) trip functions are factory-set and cannot be adjusted in the field.
