Protecting human lives with motorized remote racking, and safeguarding capital assets with continuous online surge arrester, thermal busbar, and partial discharge monitoring. Engineered for medium and high-voltage substations.

Arc-Flash Hazard Safety

IRRD™ – Intelligent Remote Racking Device

"Step back. Stay safe. Rack remotely."

Circuit breaker racking is statistically the single most dangerous operation in electrical substations. The IRRD™ eliminates catastrophic arc-flash injury by enabling technicians to rack 11kV, 22kV, and 33kV switchgear breakers from up to 50 meters away using a handheld wireless RF controller.

Voltage Compatibility 11kV, 22kV, 33kV Indoor & Outdoor Switchgear
Breaker Support ABB, Schneider, Siemens, L&T, BHEL, Crompton
Wireless Control Range Up to 50 Meters Line-of-Sight (Encrypted RF)
Torque Cutoff & Stalling Programmable electronic cutoff with real-time feedback
Standards Adherence IEEE 1584 Arc Flash Safety & NFPA 70E Standard
