Test Block

Features
The test block can be mounted adjacent to modular relays and systems. The test block obviates need to disturb protective system wiring for testing. Monitoring, isolation and secondary injection testing are simplified and quickly performed.

Application
HRTB01 offer facilities for monitoring and Secondary injection testing any power system protection scheme when used with the multi-fingered test plug type HRTP01.

Description
The test block carries 14 circuits. Each of which is brought out to separate pairs of terminals at the rear of case.
Each circuit comprises a pair of internal contacts which are normally sprung together to complete the circuit link though the block when the associated protective equipment is in normal service.
Access to these internal circuits for testing purposes, can be gained by removing the front cover and outing HRTP01 instead.
