SMOV25S Series Overvoltage Circuit Protection Thermal Protection SMOV25S Varistor

 

SMOV®25S thermally protected varistor is a self-protected device. It consists of a 25mm square varistor with an integral thermal disconnect designed to open in the event of overheating due to abnormal overvoltage as outlined in UL1449. The SMOV® helps facilitate SPD module compliance to UL1449 and offers quick thermal response due to the close proximity of the integrated thermal element to the MOV body. This configuration also offers lower inductance than most discreet solutions resulting in improved clamping performance to fast over voltage transients.

 

The device has a separate micro-switch, which can be used to indicate that the MOV has been disconnected from the circuit. This separate switch makes the monitoring circuitry completely isolated from the main power which ensures indicator circuit safety and simplifies the customers circuit design.

 

 

Features

• Maximum single surge capability 20 kA, 8/20 waveshape.

• Nominal Discharge Current Value: 10kA.

• Intermediate current rating: 50A/150A.

• Recognized to UL 1449.

• Lead-Free and RoHS compliant.

• Integrated micro-switch for indication circuitry/design.

 

 

Applications

• SPD applications

• AC/DC distribution

• IT/Data center

• Power supplier
