Description
Heinemann AM1-A8-A Circuit Breaker 10A 250V 50/60Hz 12.5A Trip Single Pole
The Heinemann AM1-A8-A is a single-pole panel-mount circuit breaker rated at 10 amps and 250 volts AC. It uses a hydraulic-magnetic trip mechanism, which provides time-delay overcurrent protection — tripping at 12.5A with a time-delay rating (TD) of 20. This design allows brief inrush currents to pass while protecting circuits from sustained overloads. The unit carries UL and CSA safety certifications.

Applications
Heinemann AM1-series circuit breakers were widely used as branch-circuit and equipment-protection devices in industrial machinery, electronic test equipment, power supplies, telecommunications cabinets, and military or commercial instrument enclosures. The hydraulic-magnetic operating principle makes them well suited for environments where inrush tolerance is needed — such as motor starts or capacitive loads — while still providing reliable overload protection. These breakers are commonly sourced as replacements for OEM equipment maintenance and for custom panel-building applications where a compact, stud-terminal single-pole breaker is required.
This Heinemann AM1-A8-A 10A 250V circuit breaker has been inspected and is in good used condition. It was pulled from a working environment where it was actively in service. The unit shows typical wear consistent with normal use — the body and label are intact and legible, with some scuffing and paint wear on the housing as visible in the photos. The toggle switch and terminal studs appear complete and undamaged. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
