AF0100 Arc-Flash Relays
Littelfuse AF0100 Arc-Flash Relays limit arc-flash damage by using light sensors to rapidly detect the arc and trip a circuit breaker. Littelfuse AF0100 monitors sensors, inputs, and trip-coil voltage to ensure fail-safe operation. These microprocessor-based protection relays include a secondary solid-state circuit that provides a redundant trip path in shunt trip mode. AF0100 serves electrical systems operating at any voltage (AC or DC) since it does not directly connect to the system.
