The PR21-1-5.00A-XX-V is a two-pole, push-to-reset, series-trip hydraulic-magnetic circuit protector from the Airpax™ SNAPAK® series. It is rated for 5.00A and features a fast trip delay suitable for general purpose DC and 50/60Hz circuits. This protector combines the functions of a power switch and a fuse, featuring a snap-acting mechanism that ensures immediate contact opening to minimize arcing. The trip-free design guarantees the circuit will open during an overload event, even if the actuator is forcibly held on. Its robust construction allows for reliable operation in ambient temperatures from -40°C to +85°C, making it ideal for medical equipment, business machines, and electronic data processing applications.
