Duplex Punched Steel Resistance Box

Product Description

 The Duplex Punched Steel Resistance Box is designed for precise control of electrical resistance in industrial applications. Made from high-quality punched steel, this resistance box offers excellent durability and heat dissipation. It is ideal for use in motor control circuits, heating elements, and other applications requiring adjustable resistance. The robust construction ensures long-term reliability and performance. Easy to install and maintain, this resistance box provides efficient and accurate resistance control, enhancing the performance and safety of your electrical systems.

Punched Steel Resistors:

DUPLEX Punched grid resistors consist of grids punched from corrosion resisting Nickel Chromium Alloy Sheet Steel. The inherent Strength of the steel itself is very high and owing to the pressed and reinforced con- Instruction the rigidity of the grids even higher. Punched steel grids are completely immune to shock and vibration. They function reliable under the worst operating conditions and are particularly suited for steel mill duty. They are comparatively light in weight for a given rating and are compact also.
Duplex punched steel grids available in a wide range of current ratings from 19 Amps to 234 Amps continuous and the fixing dimensions and weight of various types of grids are identical, which means that different types of grids required for various steps of resistance would have identical size and mounting dimensions.

The series connection between adjacent grids is not through pressure contact via tie rod nuts but by means of suitable individual
bolted connection copper jumpers. This completely eliminates any stress on the tie

rod and insulators which might result in damage during cycles of heating and cooling. When subjected to severe unforeseen overloads of moderate duration these grids may become red hot but undergo no damage whatsoever and retain their shape after over load disappears.
