Paneltronics 'A' Frame Magnetic Circuit Breaker - 25 Amps - Double Pole

The Paneltronics "A" Frame Magnetic Circuit Breaker — 25 Amps, Double Pole is a marine-grade electrical distribution component engineered for reliable branch circuit protection in both AC and DC power systems. This breaker integrates into Paneltronics electrical distribution panels to provide automatic overcurrent protection, meeting rigorous American Boat and Yacht Council (ABYC) standards for non-ignition-protected applications. The 25-amp rating handles moderate to high-current branch loads while the double-pole configuration protects both conductors simultaneously, critical for systems where unbalanced disconnection could create safety hazards.

Certification and compliance matter in electrical safety. This Paneltronics circuit breaker carries UL 1077 recognition for U.S. applications and CSA certification for Canadian use, confirming it meets recognized standards for marine electrical systems. The trip-free design (compliant with ABYC E-11.12.1.7.2.2) ensures the breaker will interrupt current even if the handle is held in the on position during an overload condition—a critical safety feature in demanding environments. Manual reset operation requires deliberate action to restore power after a fault, preventing automatic reclosure that could mask an underlying electrical problem and allowing time for inspection before reactivation.

This breaker serves vessel operators, marine electricians, and offshore system integrators who demand UL/CSA-listed components for insurance compliance and safety certification. Whether protecting navigation lighting circuits, cabin power distribution, or auxiliary 24-volt DC systems common in larger vessels, the 25-amp double-pole format addresses circuits drawing moderate sustained current without undersizing protection or introducing nuisance trips. The compact form factor (2 x 2 x 3 inches, 0.3 lbs) fits standard Paneltronics panel architecture, simplifying installation and replacement in retrofit or new-build marine electrical systems.

Magnetic circuit breakers are the standard in marine DC and hybrid AC/DC systems where conventional thermal breakers may react poorly to cold-start inrush currents or extended motor starting cycles. The magnetic trip mechanism responds instantly to severe overload and short-circuit conditions, protecting wiring and load components from arc flash and thermal damage. For anyone upgrading or maintaining a Paneltronics distribution panel, this breaker ensures your branch circuit protection meets modern marine electrical standards.
