Towe Ap B50-Pro 4P Three-Phase Power Class B Protect Gap Discharge 4 Modules Iimp:50Ka 10/350 Up 2.0Kv Lightning Arresters
- Model NumberAp B50-Pro 4P
TPS B50-PRO closed lightning arresters, is a unipolar voltage switching energy surge protector. Products are small, a large surge discharge capacity, low voltage protection level, fast response, small-wheeling. Internal use compact discharge gap closed structure minimizes injection spark discharge gap and environmental contamination. Discharge gap with excellent resistance to arc erosion properties of special alloy materials, precision made, when the gap voltage does not exceed the maximum continuous operating voltage, due to the effect of clearances, the inter-electrode high-impedance state; When the voltage exceeds the ignition voltage, the gap is breakdown, arcing occurs, the surge of energy release; Meanwhile, the discharge arc extinction board crashed reduce wheeling; freewheeling completely cut off, the discharge gap has returned to a high-impedance state.
TPS B50-PRO NPE closed lightning arresters, is constructed with TPS B50-PRO TT / TN power systems "3 +1" and "1 +1" circuit protection specifically designed specifically for the protection of the neutral line N and PE equipotential connection between.

TPS B50-PRO closed lightning arresters, voltage electrical devices designed to protect against direct lightning and surge damage Cheng and design, as Class I (Class B) surge protection, low voltage power supply system installed in 220/380V grid into the line or total distribution boards for phase line L LPZ0A and LPZ1 zone interface between the neutral line N equipotential lines with protective PE and phase L and neutral N connections between the TT , IT, TN-S, TN-C and TN-C-S power supply system to provide lightning or surge over voltage protection.
Power phase line (L), neutral (N), respectively, corresponding surge protectors access terminals to ensure secure and reliable, and the surge protector ground and ground to make a good electrical connection.
Product no special maintenance, surge protector should be checked regularly working conditions, such as lightning put the insulation resistance of electrical resistance between the electrodes is less than 2MΩ when its front open space, the fuse is tripped, it is timely maintenance or replacement module.
