Features
- The test block obviates need to disturb protective system wiring for testing, monitoring, isolation and quickly performed.
- HFTB01 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 HFTP01 instead.
