Our Resistors.
Your reliable power and control systems.
Crohm Resistors designs and manufactures braking resistors, neutral grounding resistors, high-resistance grounding systems and custom power-resistor assemblies — engineered in Cincinnati, Ohio.
Resistors for every power & control need
From light-duty braking to high-current grid banks and grounding systems — engineered, enclosed and finished to your specification.
Braking Resistors
Dissipate regenerated energy from AC variable-speed drives during deceleration and overhauling loads, preventing over-voltage shutdowns.

Built to order
Custom-engineered assemblies with the enclosures, finishes and interconnections your installation demands.
Safety first
HRG systems cut arc-flash exposure by up to 98% and limit ground-fault current to protect people and equipment.
Proven standards
Neutral grounding resistors designed and factory-tested to IEEE Standard 32, ISO 9001 certified manufacturing.
