CVP-FR series magnetic circuit protectors provide low-cost power switching, reliable circuit protection and accurate circuit control for equipment in the international marketplace.
CVP-FR series are for those applications where the unit’s inherent attributes are desired, but compliance with the various standards is not required.
CVP-FR series have been tested and approved in accordance with UL 1077 and UL489 requirements for UL recognition and approved to TUV.
They meet IEC spacing requirements.CVP-FR series has achieved two new enhancements, including a single pole, 125 amp rating with TÜV approval, and a parallel 4-pole version with 400 amp rating.
The actuator support with Long Handle Actuator,Short Handle Actuator,Flat Rocker Actuator,Angle Rocker Actuator and remote control.The Number of Poles is 1p,2p,3p,4p,Barriers with UL489 certificate.Current rating amperes is 0.5-125A.2P Parallel:101~200A;3P Parallel:201~300A;4P Parallel:301~400A.

What are magnetic circuit protectors?
How do they work?
What are the benefits of using them?
Magnetic circuit protectors are devices that use a magnetic field to open and close an electrical circuit.
They work by detecting a change in the current flowing through the device and then either opening or closing the circuit accordingly.
The benefits of using them include their low cost, their ability to switch large amounts of power, and their high reliability.
