Product Description

Buy various high quality Speed Control Resistor online globally in various models having high efficiency and longer service life as per changing market demands

National Resistors has been successfully designing and exporting Speed Control Resistor that has laid down the standard for reliability, quality and service life for several decades. Speed Control Resistor for AC or DC Motors, designed by us in line with customers requirement at specified starting torque or for limiting initial inrush current to an acceptable value, enables the operator to determine the appropriate motor speed for the specific application. Mainly these are used for cranes. Rating can be 2 minute, 5 minute, 10 minute, continuous or intermittent. Material of resistor is normally Stainless steel AISI-304, AISI -410 or AISI 430 or FeCrAl-AISI-406.

Speed Control Resistor, manufactured by us from high-strength S.S with temperature coefficient, can also be easily adapted to operate at the nominal operating temperature from automotive power supply as well as characterizing versatility. As a well reputed Speed Control Resistor Exporter & Manufacturer based in Delhi India, National Resistors aims to realize substantial growth through designing an innovative product line developed with leading-edge technology as well as effectively responding to growing demand from emerging markets. The company has sustained an unflinching commitment to the excellence of quality with the corporate philosophy through bringing about improvement and enhancement in components and technology.

We are offering Starting/Speed Control Resistor. For starting / Speed Control of A.C or D.C. Motors, resistors are manufactured as per customers requirement at specified starting torque or for limiting initial inrush current to an acceptable value. Mainly these are used for cranes. Rating can be 2 minute, 5 minute, 10 minute, continuous or intermittent. Material of resistor is normally Stainless steel AISI-304, AISI -410 or AISI 430 or FeCrAl-AISI-406.
