Surge Protective Devices (SPDs) of Type 3, also known as surge arrestors or transient voltage surge suppressors (TVSS), are the final line of defense in a coordinated surge protection strategy. These devices are specifically designed for installation directly at the point of use, such as in terminal equipment, socket outlets, or distribution boards close to sensitive loads. They feature a low voltage protection level (Up) typically below 1.5 kV and are characterized by a nominal discharge current (In) of 5 kA or less, with a maximum discharge current (Imax) of up to 10 kA. Type 3 SPDs are often combined with a fine protection stage and may include integrated thermal disconnection and remote signaling contacts for monitoring. They are available in single-pole (1P), two-pole (2P), and three-pole (3P) configurations, with rated voltages from 230/400 V AC and frequencies of 50/60 Hz. Common form factors include pluggable modules for DIN rail mounting or integrated into power strips.
These devices are essential in environments where sensitive electronic equipment is present, such as data centers, telecommunications rooms, medical facilities, industrial control systems, and residential smart home installations. They protect against residual surges from upstream Type 1 and Type 2 SPDs, as well as switching transients generated within the local network. Typical applications include protection of PLCs, variable frequency drives (VFDs), security systems, and audio/video equipment. They are installed in final sub-distribution boards, socket outlets, or directly at the equipment inlet, ensuring compliance with IEC 61643-11 and EN 61643-11 standards.
The OBO BETTERMANN Type 3 surge protection category includes subcategories such as pluggable surge protection modules for socket outlets (e.g., OBO MC 3-P 230/400 V), compact surge arrestors for terminal equipment (e.g., OBO FS 3-P 230/400 V), and integrated surge protection in power strips. The article codes typically follow a pattern like "OBO MC 3-P 230/400 V" where "MC" indicates the series, "3-P" denotes the number of poles, and "230/400 V" specifies the rated voltage. Other common codes include "OBO FS 3-P 230/400 V" for fine protection series and "OBO TS 3-P 230/400 V" for terminal series. These products are designed for DIN rail mounting and often include visual status indicators and remote signaling contacts.
