Elevator & Escalator Drive Systems

Elevators and escalator drive systems must comply with safety codes while delivering enough power to move heavy loads. Littelfuse’s electronic components meet these demands. In addition to rectifiers and inverters for electric motors, we supply shunt trip disconnect switches that automate safety shutdowns and TVS diode arrays that protect circuits and riders from shocks and lightning strikes.
