Surge protection devices (SPDs), also known as surge arrestors or transient voltage surge suppressors (TVSS), are critical components for safeguarding electrical installations against overvoltages caused by lightning strikes or switching operations. Type 1+2 arrestors combine the high-energy discharge capability of Type 1 (10/350 µs waveform) with the overvoltage limitation of Type 2 (8/20 µs waveform), making them ideal for main distribution boards in office and housing applications. These devices typically feature a rated voltage of 230/400 V AC, a nominal discharge current (In) of 20 kA per pole, and a maximum discharge current (Imax) of up to 50 kA. They are available in configurations such as 1P, 1P+N, 3P, 3P+N, and 4P, with pluggable modules for easy replacement. Key parameters include the voltage protection level (Up), which should be below 1.5 kV for sensitive equipment, and the short-circuit withstand capacity (Isc) up to 25 kA. Common standards include IEC 61643-11 and EN 61643-11, ensuring compliance with international safety regulations.

These surge arrestors are primarily installed in main low-voltage switchboards, sub-distribution boards, and building entrance panels. They protect sensitive electronic equipment such as computers, servers, HVAC controls, lighting systems, and security devices in residential and commercial buildings. In office environments, they safeguard critical infrastructure like network switches, UPS systems, and telecommunication equipment. For housing applications, they protect household appliances, smart home systems, and entertainment electronics. Type 1+2 devices are also used in industrial control panels, photovoltaic systems, and EV charging stations where combined lightning and surge protection is required. Their compact design allows for easy integration into existing electrical enclosures with DIN rail mounting.

The main subcategories include pluggable surge arrestors (e.g., OBO BETTERMANN V20-C/3-PH, V25-B+C/3-PH, and MC50-B/3-PH), which feature a modular design with thermal disconnection and visual status indication. The article codes typically follow a pattern like "V20-C/3-PH" where "V20" indicates the series, "C" the protection class, "3" the number of poles, and "PH" the phase configuration. Other relevant articles include the OBO BETTERMANN TNC-25/3-PH for TN-C systems and the V50-B+C/3-PH for higher discharge capacities. These devices often come with optional remote signaling contacts (e.g., V20-C/3-PH-FS) for integration into building management systems.

Partnering with Electric Automation Network ensures access to genuine OBO BETTERMANN surge protection devices with real-time pricing and up to 65% discount compared to market rates. Our engineering team provides personalized technical support for selecting the correct SPD type based on your system's lightning protection level (LPL), risk assessment, and equipment sensitivity. We offer express worldwide shipping with tracking, ensuring your critical components arrive within 3-5 business days. Each product includes detailed technical documentation, wiring diagrams, and installation guidelines. Our multilingual portal allows you to compare specifications, check stock availability, and place orders 24/7.
