Varistor surge protector type 2 (class C) four-pole SPMO20C\4P

Electrical installation protection with surge limiters Spamel

Four-pole Type 2 (Class C) surge limiter SPMO20C\4P is a key element in protecting electrical installations in residential buildings, single-family homes and small commercial facilities. Its task is to protect against the effects of surges that can damage sensitive electronic devices. The limiter effectively minimizes the risk of surge currents entering the power supply network, ensuring the continuity and safety of the installation.

Surge limiters from the SPMO series, manufactured by Spamel, are designed for easy mounting in electrical switchboards. The product has undergone rigorous testing at the Institute of Plasma Physics and Microsynthesis, confirming its high quality and reliability. Using a surge limiter is an investment in the long-term safety and trouble-free operation of the electrical system.

Key features and application

This four-pole surge limiter of class C is designed to protect against differential and common mode surges. Thanks to this, it provides comprehensive protection of the electrical installation against various types of interference. It is compatible with TN-S and TN-C networks, making it a universal solution for most typical installations.

The limiter is characterized by high efficiency at a rated voltage of AC 230/400 V and a maximum continuous operating voltage of AC 275 V. Its ability to absorb surge energy (nominal discharge current In 20 kA, maximum discharge current Imax 40 kA) guarantees effective protection even in the event of strong surges. In addition, remote fault indication allows for quick identification of the need for limiter replacement, increasing the safety of the entire system. Mounting is on a TH35 rail, and the materials used in production (PA6 with UL94-V0 flammability test) ensure durability and resistance to environmental conditions.
