Type 2 surge protective device (class C) SPMO20C

Electrical installation protection with varistor SPMO20C

This type 2 surge protector (class C) is a key element in protecting electrical installations in residential buildings, single-family homes, and smaller commercial facilities. Its function is to protect against the effects of surges that can damage sensitive electronic devices. This limiter effectively minimizes the risk of failures caused by sudden voltage spikes, ensuring uninterrupted power supply and safe operation.

Spamel limiters, including the SPMO20C model, are designed to work with electrical distribution boards and are mounted on a TH-35 mm DIN rail. Compliance with IEC/EN 61643-11 guarantees high quality and reliability. The product has been tested at the Institute of Plasma Physics and Microsynthesis, confirming its effectiveness and safety.

Characteristics and application

The SPMO20C limiter is a class 2 component, which means it is designed to protect against surges of medium energy. Its construction based on varistor technology allows for a quick response to sudden voltage changes and effective damping of current pulses. The AC rated voltage of 275 V makes it an ideal solution for standard power grids. The IP20 degree of protection indicates protection against accidental contact, which is important in the context of safe use inside buildings.

Mounting on a TH-35 mm DIN rail facilitates installation and integration with existing electrical infrastructure. This allows both professional installers and end-users to quickly and efficiently introduce limiters into the surge protection system. It is worth remembering that regular inspection of the limiter's condition (indicated by the green/red color of the insert) allows maintaining an optimal level of protection.
