The PR21-4-6.00A-XX-V is a two-pole push-to-reset hydraulic-magnetic circuit protector from the AIRPAX SNAPAK® series, combining power switching and reliable circuit protection in a single compact package. This device features a two-pole toggle configuration with a rated current of 6.00A and incorporates a hydraulic-magnetic mechanism for accurate, snap-acting protection. The unit is designed for panel mounting with a recommended center distance of 1.375 inches [34.93 mm] between panel openings for proper installation clearance. The push-to-reset actuator provides manual control with a flush OFF position and ON engagement, while the device integrates the functions of a power switch, fuse, and fuse holder into one component. This design reduces assembly requirements and inventory management for OEMs, making it ideal for aerospace, industrial control, and power distribution applications where reliable circuit protection and switching are essential.
