We hold expertise in offering a wide gamut of precision engineered Relay Test Block. In order to manufacture this range, our dexterous team of professionals use premium quality raw material with cutting-edge technology. Owing to the strong construction and durability, these blocks are highly admired among clients. The offered blocks are used to protect relays testing in control relay panel and also in data acquisition for network analysis. We offer these Relay Test Block to the clients at very reasonable price as per their specific need.
NWRTS range of Relay Test Block are housed in size E2 unit in the Epsilon range of enclosures.
NWRTS range of Relay Test Block and NWRTP range of Test Plugs facilitates safe and in-situ monitoring and testing of Power Systems Protection schemes.
NWRTS range of Relay Test Block comprises of 14 pairs of spring loaded contacts.Each is independently terminated at the rear as 28 separate terminals, each with an M4 screw outlet for shaped pre-insulated crimp terminations for connecting external wiring and 2 nos. blades 4.8 mm x 0.8 mm cross section to accept snap-on connections.
Each individual circuit consists of a pair of contacts that remain closed to complete the circuit link when the related protective system is in normal service mode. The NWRTS cover,when in place provides adequate save gaurds from electric shock hazards.
Upon removal of the NWRTS cover,an orange coloured strip on the face of the Test Block provides ample visual indication that the system is out of service.Earth terminal is provided at the rear top of NWRTS.
Internal circuits for the purpose of testing can be accessed on the removal of the front cover.The cover when removed will interrupt the circuit between 13 and 14 as the metallic probe attached to the inside of NWRTS-01 that closes the circuit between terminal 13 and 14 too is withdrawn.Upon routing the main DC auxillary supply to the protection system or the relay through this circuit,removal of the Test Block front cover will thereby prevent inadvertent tripping of the protection system under test.
