Buss Aircraft Fuses

Mechanical Indicating - Limiter type

?ACH limiters are designed to meet the very rigorous require-ments of high speed, high performance aircraft.

?Isolate faults or grounds in aircraft electric systems of 120/208 volts 400 cycles AC or 125 volts DC.

?ACH limiters give visual indication when open by a spring-activated pin that extends from the limiter body.

?The knife blade terminals on ACH limiters are silver-plated.?Limiters are made with a silicone body that assures reliable performance under severe conditions.

?Designed to withstand exposure to moisture, fungus, salt spray, sand and dust, and mechanical vibration and shock.
