Punched Grid Resistors

Overview

BCH unbreakable Punched Grid Resistors ( PGR) are made robust, versatile & yet economical for use as starting & speed control resistors for complete range of AC&DC Motors.

BCH Resistors are suitable for extreme vibration conditions. TIG welded staggered grid pattern design for consistent current path & ensure maximum air circulation.

Range & Specification

  • Resistance : 0.1 to 16 ohms per bank
  • Continuous current rating : 19A to 200A

Applications

  • Speed Control Resistors
  • Starting Resistors for AC and DC Motors
  • Dynamic Braking Resistors
  • Neutral Grounding Resistors (upto 11KV)

Features

Special Chromiun Steel Alloy (AISI406) for :

  • Higher resistivity (approx 70% higher than others) This results in overall light and compact unit
  •  Low temperature coefficient (approx 72% lower than others) This means negligible change in resistance values despite grid temperature variations (very important parameter in applications like crane controls)
