Surge Protective Device(SPD) AC 50/60Hz UC 385V TZG40 40KA

The Original TOMZN Surge Protective Device (SPD) 2P and 4P AC is a reliable electrical protection solution designed to safeguard residential, commercial, and industrial electrical systems from harmful voltage surges caused by lightning strikes, grid switching, and electrical faults. Available in 2-pole and 4-pole configurations, it provides effective surge protection for single-phase and three-phase AC systems, including 230/400V networks. The 4-pole model protects all three phases and neutral lines by safely diverting excess surge energy to the ground, reducing the risk of damage to sensitive electrical equipment such as air conditioners, refrigerators, televisions, computers, and other electronic devices. Designed with a compact modular structure, this SPD features a 35mm DIN rail mounting system for easy installation alongside MCBs and RCCBs in distribution boards. With visual status indicators on selected models, users can quickly monitor the protection module condition. Suitable for homes, offices, shops, villas, small factories, workshops, and other low-voltage distribution systems, the TOMZN AC Surge Protective Device offers dependable performance, enhanced electrical safety, and extended equipment lifespan.
