Varistor surge protector type 1+2 (class B+C) single-pole SPMO30B+C\1P

Protection of electrical installations against overvoltage – reliable surge arrester SPMO30B+C\1P

This single-pole surge arrester type 1+2 (class B+C) from Spamel is a key element in protecting electrical installations in residential buildings, single-family homes, and smaller commercial facilities. Its task is to protect against the effects of lightning strikes and other overvoltages that can damage sensitive electronics and electrical devices.

The SPMO30B+C\1P arrester effectively protects against surge currents penetrating the power line, minimizing the risk of failure and ensuring continuity of supply. The product meets the requirements of IEC/EN 61643-11, which confirms its high quality and reliability – it has also been tested at the Institute of Plasma Physics and Microsynthesis.

Why choose the SPMO30B+C\1P arrester?

• Versatile application: ideal for electrical switchboards in residential and commercial buildings.
• Effective protection: provides protection against overvoltages caused by both direct and indirect lightning strikes, as well as switching surges.
• High efficiency: nominal discharge current of 30 kA and maximum discharge current of 60 kA guarantee effective protection even with large surges.
• Fast response: voltage protection level of ≤ 1.5kV ensures a quick limitation of overvoltages to a safe level.
• Durable construction: high-quality materials (PA6 and PBT) with UL94-V0 certificate ensure resistance to external factors and long-term operation.
• Convenient installation: designed for mounting on TH35 rail, which facilitates installation in the switchboard.
• Status indication: optical indication of the insert status allows for quick identification of damage and the need for replacement.

This arrester is compatible with TN-S/TN-C networks, and its rated voltage AC is 230/400V. It is adapted to work in a wide range of temperatures (-40°C to +85°C) and humidity (≤ 95%), making it a reliable solution in various environmental conditions. Installation with appropriate overcurrent protection is recommended – the maximum additional fuse is 125 gL/gG. Remember the correct cross-section of connection wires: rigid 6.0 – 35mm² and flexible 4.0 – 25mm².

Choosing the SPMO30B+C\1P surge arrester is an investment in the safety of your electrical installation and peace of mind. It is a solid solution for professionals and demanding end-users.
