Resistor Products
Eleven families of power and control resistors — braking, grounding, grid, wirewound and custom assemblies. Every unit can be enclosed, finished and engineered to your application.
Braking Resistors
Dissipate regenerated energy from AC variable-speed drives during deceleration and overhauling loads, preventing over-voltage shutdowns.

Case Resistors
Hermetically sealed aluminum-housed resistors for light-duty braking, heating and AC/DC loads in tight spaces.
View product
Edgewound Resistors
Stainless edgewound elements (15–100 A) for medium-to-heavy braking, crane, transit, elevator and mining controls.
View product
Grid & Ribbon Resistors
High-current grid and continuous-ribbon resistors on double-insulated frames for the most demanding applications.

High Resistance Grounding Systems
HRG systems limit ground-fault current, cut arc-flash exposure by up to 98%, and pinpoint faults without shutting down.

Neutral Grounding Resistors
NGRs connect between the system neutral and ground to limit fault current — designed and tested to IEEE Standard 32.

Oil and Gas Braking Resistors
Heavy-duty natural convection and fan-cooled braking resistors engineered for drilling, production and high-horsepower VFD applications in the oil and gas industry.

Wirewound Resistors
Open-frame wirewound resistors, 0.2–300 Ω, for braking, speed regulation, wye-delta starting and neutral grounding.
