ISPRO-K BS(R) 75 (3+0)
The ISPRO BS(R) 75 (3 + 0) series of over voltage surge protective devices has been developed to protect against partial direct and indirect lightning discharges and is intended to provide protection in zones 0A – 1 as per IEC 62305.
The (3 + 0) range is intended to be used on TNC three phase networks with PEN conductor.
The circuit topology consists of three varistor stages each protected by a thermal disconnection device. Each three phase unit comprises a total of three high performance dual MOV blocks, providing a high surge rating suitable for primary service entrance applications.
A unique indicator monitors all disconnectors and brings up a common status fl ag if any one stage should fail.
