Class B for 1-Phase Surge Protection Device Manufacturer in India
Combined lightning current and surge arrester (T1 + T2) for the service entrance
Description
The Class B for 1-Phase Surge Protection Device manufactured by SG Power Products Pvt. Ltd. is a DIN rail module, two-section, divisible, classified I + II / T1 + T2 to IEC and type T1 + T2 to EN. It is designed for TN power supply systems and protects installations from lightning currents and transient overvoltages caused by switching operations and indirect lightning effects.
The module is rated for a nominal voltage of 24V AC/DC at a nominal frequency of 50/60 Hz. It measures 71.2 mm × 95 mm × 71.2 mm (incl. DIN rail 7.5 mm) and occupies a horizontal pitch of 4 Div. on the rail. This model carries no surge protection fault message, so module condition is verified during scheduled inspection.
The housing uses PA 6.6 / PBT insulating material in Jet black (RAL 9005) with a UL 94 V-0 flammability rating and IP20 (only when all terminal points are used) degree of protection. It operates and is stored at -40 °C ... 80 °C and 5 % ... 95 % humidity, withstands 25g shock and 5g vibration, and is tested to IEC 61643-11 and EN 61643-11.
