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)
