ISPRO-K BS(R) 100 (4+0)
The ISPRO-K BS(R) 100 (4 + 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 (4 + 0) range is intended to be used on TNS three phase networks with separate N and PE conductors.
The circuit topology consists of four varistor stages each protected by a thermal disconnection device. Each three phase unit comprises a total of four high performance dual MOV blocks, providing a high surge rating suitable for primary service entrance applications.
A unique indicator monitors all thermal disconnectors and brings up a common status fl ag if any one stage should fail.
