The Sensata PR21-4-8.00A-20394-1-V is a Snapak series magnetic hydraulic circuit protector. This component combines the functions of a power switch, fuse, and fuse holder into a single unit, simplifying OEM assembly and reducing inventory.
This specific model is a 2-pole protector with a panel mount type and a push-to-reset actuator. It is designed to operate at DC or 50/60Hz frequencies, with 400Hz units also available. The snap-acting design ensures immediate contact opening and closing, minimizing arcing and preventing contact teasing.
Typical applications for the SNAP AK® series include office appliances, electronic data processing, medical equipment, business machines, and vending machines. The push-pull versions are particularly suited for medical instrumentation and automotive production transfer lines where accidental turn-off is unacceptable.
The protector is UL Recognized, CSA Certified, and TUV Approved. It meets spacing requirements of IEC 950 for basic and functional insulation for front panel mounting.
