Polycarbonate housing having UL 94 V-0
All Rishabh meters are housed in robust case with classical finish. The case is made of polycarbonate, which is flame retardant and non-drip and confirms to international regulations UL 94 V-0. Polycarbonate is a very tough and light weight engineering plastic material which has got the best mechanical properties very close to a metallic housing. It is 10% glass filled, glass fibers give it extra toughness.
Description of DIN rail series meter
These DIN rail series of EQ35, PQ35 and ZQ35 meters are designed for the measurement of AC/DC Current, AC/DC Voltage and Frequency which utilizes 35mm DIN rails for mounting. The mounting width is 45mm.
Knife edge Pointer
Pointer edge is a knife edge and is made of aluminium sheet of 0.05mm thickness. This makes it very light weight but at the same time, it is rigid by a specially designed V-profile. The sheet used is a pre-coated aluminium sheet so that the adhesion of the paint is very good. The pointer is fitted on to the cross arm by a special flapping process so that it can never disengage even in extreme temperature or presence of vibration or shock.
Terminal screws and clamps
Self lifting terminal screws are connected to the terminal clamps. Self lifted clamps gets lifted with the terminal screw while unscrewing, this simplifies clamping of the connectors or wire and save the time
