Siemens HHED62B125L - 125 A, 600 V, 2-Pole Circuit Breaker | AmpState

Meet the Siemens HHED62B125L — a robust 125A, 600V, 2-pole molded case circuit breaker designed to safeguard panelboards and load centers with precision. Built for dependable branch-circuit overcurrent and short-circuit protection, this breaker keeps critical electrical systems up and running while occupying minimal panel real estate.

Why the HHED62B125L stands out

• Compact molded-case design maximizes panel space, making it ideal for modern electrical layouts where space is at a premium.
• Thermal-magnetic trip unit delivers stable, repeatable protection by combining a thermal element for sustained overloads with an instantaneous magnetic trip for short circuits.
• 125A at 600V, 2-pole configuration provides solid, reliable protection for demanding branch circuits and heavy-load feeders.
• OEM-compatible — designed to pair with matching Siemens OEM load centers and panelboards for coordinated protection and predictable performance.
• Versatile applications across residential, commercial, and light industrial environments, particularly where high-current protection and compact sizing are needed.
