Surge protection devices (SPDs) are critical components in modern electrical installations, designed to limit transient overvoltages and divert surge currents away from sensitive equipment. Type 2 arrestors, as defined by IEC 61643-11, are permanently installed in sub-distribution boards and are rated for medium-energy surges, typically with a nominal discharge current (In) of 20 kA (8/20 µs) and a maximum discharge current (Imax) of up to 65 kA. These devices protect against switching transients and indirect lightning strikes, featuring a voltage protection level (Up) below 2.5 kV for 230/400 V networks. They are available in single-pole (1P), two-pole (2P), three-pole (3P), and four-pole (4P) configurations, with thermal disconnection and visual status indication. In the industry, they are also known as secondary surge arresters, lightning current arrestors, or transient voltage surge suppressors (TVSS) for AC power systems.
These Type 2 SPDs are primarily installed in sub-distribution panels, main distribution boards, and control cabinets within commercial, industrial, and residential buildings. They safeguard critical loads such as PLCs, variable frequency drives (VFDs), HVAC systems, lighting control panels, and security systems. Common applications include data centers, manufacturing plants, telecommunications facilities, and renewable energy installations like photovoltaic (PV) systems. They are also used in building management systems (BMS) and motor control centers (MCCs) to ensure operational continuity and prevent costly downtime.
The main subcategories within this range include the OBO BETTERMANN MC series (e.g., MC 20-B, MC 50-B) and V20 series (e.g., V20-3, V20-4). Key article codes follow a pattern like "OB0503-1P" for single-pole units, "OB0503-3P" for three-pole, and "OB0503-4P" for four-pole configurations. Variants include models with remote signaling contacts (e.g., MC 20-B FS) and those with higher nominal discharge currents (e.g., MC 50-B with In=25 kA). The coding typically includes the series prefix, number of poles, and optional suffix for accessories like pluggable modules or base elements.
