Ground Fault Protection

From Esterline Power Systems / Leach International

The wear and tear of wiring harnesses can create a safety issue in commercial aircraft, particularly in the aging ones.However, an approved and proven technology exists that can detect and isolate the electrical faults, which can otherwise escape the harness and create hazardous situations in the aircrafts fuel tanks.

Products & Services
Electrical Contactors
Electrical contactors are used to switch high power in power circuits. Unlike relays, these electrical devices are normally connected directly to the load or current-carrying circuit.
Time Delay Relays
Time delay relays and solid state timers use solid state electronic devices to provide a time delay.
Aerospace Contactors
Aerospace contactors are high-performance, high-capacity, circuit controls designed for aerospace applications.
