Power Class B Surge Protector LP-75B

The LP-75B is a lightning protector unit, or surge protective device, designed for power class B. It protects the building's low-voltage main distribution box against overvoltage caused by a lightning strike or by mis-operation on the power network. The unit has a large current capacity with low residual voltage, and built-in temperature control and circuit-breaking technology for safe operation. A notice window shows the module status at a glance, and an optional telesignalisation interface allows the protector to be monitored remotely. Modules combine into 1P+N, 2P, 3P+N, 4P and other arrangements to suit different electrical network systems.

Features

• Large current capacity: 80 kA nominal and 120 kA maximum discharge current (8/20 µs)
• Low residual voltage, with a voltage protection level below 1.5 kV
• Built-in temperature control and circuit-breaking technology
• Status window: no light indicates normal, red indicates a failed module
• Optional telesignalisation monitoring interface for remote monitoring
• Wiring arranged to reduce conductor resistance
• Modular combinations such as 1P+N, 2P, 3P+N and 4P
• Flame-retardant reinforced nylon housing (UL 94V-0)

Applications

• Building low-voltage main distribution boxes
• Power class B surge protection
• Three-phase systems, in 3P and 4P wiring arrangements
