LPI® Power Line Shunt Single Mode Protection: SST150

· Product Description
The SST150 is a single mode power line shunt surge protection device rated for 50kA 8/20μs single shot surge capacity (Imax). The unit is designed for mounting at main power switchboards and distribution boards in category C locations as per the IEC and other international standards.

The SST150 is designed to provide surge and transient protection in compliance to IEC 61643 international standards. The surge protection design allows it to be configured for Ph-N or Ph-E or N-E protection applications for single or multiple phases as required, it is also designed for easy mounting on standard 35mm Din rail.

The unit comes with fast, responsive Metal Oxide Varistors (MOV) to provide effective surge protection with low let-through voltage to protect sensitive electronics and electrical circuits. The SST150 is fitted with thermal disconnects which will respond should the varistors be overloaded. In this case, the indicator changes status to red, and alarm contacts change over.

The unit comes as a two part item. The base is hardwired into the circuit to be protected, and the protection module is plugged into this base. This enables easy replacement of protection modules should they be degraded or damaged by excessive transient activity.
