Circuit breaker selection in industrial and military power systems is a system-level decision, not a catalog exercise. Factors such as inrush current, trip characteristics, environmental conditions, and variant-level configuration play a critical role in preventing nuisance tripping and ensuring reliable operation in harsh environments.
Why does a circuit breaker work perfectly in the lab but fail in the field?
The answer is not a defect — it is physics.
Most false trips are caused by inrush current, DC ripple, temperature and vibration.
AIRPAX hydraulic-magnetic circuit breakers are designed to ignore short electrical transients and respond only to real overloads, making them the preferred choice for military, medical, and mission-critical power systems.
The Auxiliary Switch is the feedback link between your breaker and control system — indicating ON, OFF, or TRIPPED status in real time.
Built into Airpax™ magnetic circuit breakers and distributed in Israel by Amironic Ltd., it provides accurate isolation between power and control circuits, enabling remote monitoring, fault detection, and safety interlocks in industrial, military, and medical systems.
A Trip Coil (Shunt Trip Module) transforms a standard thermal-magnetic circuit breaker into a smart, remotely controlled protection device.
By applying a short control-voltage pulse, the coil activates the breaker’s trip mechanism — enabling remote shutdown, E-STOP functionality, or automated system protection.
The result is a compact, intelligent solution that combines relay control, overload protection, and remote disconnection in a single unit.

MIL-PRF-39019 and MIL-PRF-55629 set the standard for military-grade hydraulic-magnetic circuit breakers. 39019 is built for extreme environments—shock, vibration, salt, and heat—while 55629 offers a cost-effective option for general military use. Amironic, representing Sensata Airpax, delivers both solutions with expert local support.
APM Hexseal’s circuit breaker boots provide rugged, intelligent sealing for toggle-style breakers, with options for front-panel or back-panel mounting—each tailored to specific engineering needs.
Front-mounted boots are ideal for quick retrofits and easy access on existing panels, while back-mounted boots integrate cleanly into the panel for a flush, secure seal.
Made in the USA from patented RUBRGLAS™ silicone, all models offer IP68 protection against water, oil, dust, and vibration—perfect for military, marine, and industrial environments.
We are pleased to announce the release of the LineGard™ PGFM Series to our global distribution network. The LineGard™ PGFM product family provides ELCI (equipment leakage) ground fault sensing and operates in tandem with the Airpax™ LEL series, UL 489 listed circuit breaker, with shunt trip and auxiliary switch.
In the demanding world of military and industrial electronics, power protection is a critical component that can make or break a system’s reliability and performance. GILGAL’s innovative Input Power Protection solutions are setting new standards in this crucial field, offering unparalleled advantages for DC power systems.
Amironic, representing Sensata Airpax in Israel, is proud to introduce the ICLR/ICLRH/ICLMR/ICLMHR series, a game-changer in power management, offering unparalleled remote control and performance capabilities. Here’s why you should consider integrating it into your system.
