Product description

Class I B + C
he ISPRO BS(R) 50 series of low cost, 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.
It consists of two separate, high performance dual MOV blocks, each with a separate disconnection device.

The ISPRO-G is an 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.
It consists of an encapsulated air gap device (GDT), and is used as a galvanic separation between the N-PE conductors in a 1 + 1
or 3 + 1 power distribution system (TT networks).

The ISPRO-K 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.
