DAV make Test terminal blocks
3phase/4 wire

Description

The test block and the cover are made of black Bakelite moulding. The moulded barriers are provided in base between adjacent terminals to give complete protection against flash over. The cover is secured in place by knurled sealing nuts. All terminals, shorting links, screws are of brass and nickel plated to prevent corrosion.

Terminal Arrangement

The basic terminal arrangement consists of three voltage terminals and a neutral terminal together with 3 sets of current terminals. The voltage in neutral terminals and movable links which allow the meter or relay to disconnect from their normal supply voltage. The links are connected to the terminals by means of screws and knobs. When several meters are tested their current circuits should be connected in series. If meter are to be tested individually, separate test terminal blocks are required for each meter.

Dav make Semaphore Indicators Semaphore Indicator‘DAV’ Automatic Semaphore Indicators type NTC are used in MIMIC diagram on Control and Instrumentation Panel to indicate open or close position of isolator, Earth switch, Circular Breaker, PT ON/OFF switch. The pointer takes up position of the supervised equipment it turn right angle when breaker, isolator et is in open position, it takes up intermediate position i.e. 45 degree on failure of supply.
