Description
Built for standalone enclosures and motor control centers, this 25A unit-mount MCCB offers versatile installation outside of standard panelboards. The inclusion of factory-installed SA1E025 line and load lugs accelerates the wiring process for electrical contractors. Operating with a fixed thermal-magnetic trip, the HHED63B025L achieves a 65kAIC rating at 480VAC. This Sentron ED-frame component provides current-limiting, reverse-feed capable protection for rigorous industrial applications.Specifications

Product FAQs
7 answersCan the Siemens HHED63B025L be reverse fed?
Yes. Because this Sentron ED-frame breaker features a non-interchangeable thermal-magnetic trip unit without specific line and load directional restrictions, it is suitable for reverse-feed applications per UL 489 guidelines.
What types of equipment are compatible with this breaker?
The HHED63B025L is a unit-mount molded case circuit breaker designed for installation in standalone enclosures, switchboards, and motor control centers that accept Siemens ED-frame breakers. It is not designed for standard residential plug-on or bolt-on load centers.
What does the L suffix at the end of the HHED63B025L catalog number indicate?
The L suffix indicates that the breaker is factory-assembled with line and load lugs included. This model ships ready to wire with lugs that accept 14-10 AWG copper or 12-10 AWG aluminum conductors.
How does the HHED6 series differ from standard ED4 or ED6 breakers?
The HHED6 series offers an extra-high interrupting capacity for 600V applications. While standard ED4 and ED6 breakers have lower short-circuit ratings, the HHED63B025L provides 18kAIC at 600VAC and 65kAIC at 480VAC for more demanding industrial environments.
Does this breaker require a specific mounting orientation?
No. As a thermal-magnetic molded case circuit breaker, the HHED63B025L can be mounted vertically or horizontally within your enclosure or switchboard without affecting its trip characteristics or protective performance.
Is this breaker suitable for direct current applications?
Yes. In addition to its AC ratings, the HHED63B025L is rated for 250VDC with an interrupting capacity of 30kAIC. This makes it suitable for industrial DC control circuits and distribution panels.
What type of trip unit is installed in the HHED63B025L?
This breaker features a fixed thermal-magnetic trip unit. It provides non-adjustable long-time thermal protection for overloads and instantaneous magnetic protection for short circuits, designated by the LI trip function code.
