Product FAQs
6 answersWhat does the "L" suffix in the HED42B015L catalog number indicate?
The "L" suffix means the breaker is factory-supplied with both line and load side lugs installed. Standard Siemens ED frame breakers are typically supplied with only load side lugs.
Can the HED42B015L circuit breaker be reverse fed?
Yes. Siemens Sentron ED frame thermal-magnetic circuit breakers can be reverse connected, provided they are not factory marked with "LINE" and "LOAD" designations.
What internal accessories are compatible with this breaker?
You can field-install internal accessories such as shunt trips, auxiliary switches, alarm switches, and undervoltage releases. Only one internal accessory module can be added per breaker, and it is typically mounted in the left pole.
Is the HED42B015L a plug-in or bolt-on breaker?
This is a unit mount breaker designed for feed-thru connections. It bolts directly to the mounting surface or bus in switchboards and motor control centers, rather than plugging into a load center busbar.
What is the modern replacement for the HED42B015L?
This legacy Sentron ED frame breaker is officially replaced by the Siemens 3VA5115-6EC21-0AA0 molded case circuit breaker.
What is the maximum frame rating for this breaker family?
The HED42B015L is part of the Siemens Sentron ED frame family, which features a compact design with a maximum overall frame rating of 125 amps for standard depth panelboards.
