PROJOY PESP 1000 T1+T2 3P DC Surge Protector

The PROJOY PESP 1000 T1+T2 3P is a three-pole, direct-current surge arrester suitable for systems with an operating voltage of up to 1000 V DC. Thanks to its combined T1+T2 protection category, it provides protection against surges with 10/350 μs and 8/20 μs waveforms.

The device has a built-in fault indicator window: a green light indicates normal operation, while a red light indicates a malfunction. In the event of a malfunction caused by overheating, the built-in safety cut-off automatically disconnects the device from the electrical grid. It is also available with an optional remote signaling contact.
