Description
Part of the Sentron ED frame family, this 20-amp unit mount molded case circuit breaker provides reliable thermal-magnetic protection for industrial applications. It installs into standard enclosures, motor control centers, and switchboards requiring high interrupting capacity. Rated for 65kAIC at 277VAC, the device features non-interchangeable trips and comes equipped with both line and load side lugs. Siemens now recommends the 3VA5120-6EC11-0AA0 as a modern substitute for new designs.Specifications

Product FAQs
7 answersWhat equipment is compatible with the HED41B020L?
This ED-frame circuit breaker is designed for use in Siemens Sentron enclosures, switchboards, and motor control centers that accept unit-mount breakers.
Can the HED41B020L be reverse fed?
Yes. Because this ED-frame breaker features a non-interchangeable thermal-magnetic trip unit, it is suitable for reverse feeding applications.
Is the HED41B020L suitable for direct current applications?
Yes, this breaker is rated for DC systems, providing an interrupting capacity of 30kA at 125VDC.
What is the difference between Siemens ED4 and HED4 circuit breakers?
The HED4 series is the high-interrupting capacity version of the standard ED4 series. The HED41B020L provides a 65kAIC rating at 277VAC, whereas standard ED4 breakers have a lower short-circuit rating for the same voltage.
What does the L suffix in the HED41B020L catalog number indicate?
The L suffix indicates that the circuit breaker is factory-supplied with both line and load side lugs installed, rather than requiring lugs to be ordered separately.
Are the trip settings on the HED41B020L adjustable?
No, this breaker features a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous trip functions cannot be adjusted in the field.
Does the HED41B020L have a removable trip unit?
No. Siemens ED-frame breakers, including the HED41B020L, have non-interchangeable trip units and are shipped as fully assembled products.
