Product Description

Stainless Steel Punched Grid Resistors

Resistors are designed to meet requirements of both A.C & D.C. Applications. The basis types of resistors are stainless steel and punched steel resistors these are manufacture for current rating from 10 to 800 Amps. Continuous resistors of higher rating are manufactured using 2 or more parallel paths. Resistors with short time rating up to 3000 Amos or even more for neutral earthing are possible which suitable for system voltage up to 11kv and above.
