E510-403-H3 TECO 400V 2.2 kW No Filter No Safe Torque Off 3 Phase
MPN: E510-403-H3
Alt. SKU: E510403H3
Why Choose the TECO E510-403-H3 AC Inverter Drive?
The TECO E510-403-H3 is a reliable compact industrial variable frequency drive from the TECO-Westinghouse E510 Compact AC Drive series, designed for efficient control of three phase motors across a wide range of automation and machinery applications. It delivers versatile speed and torque regulation using V/Hz and sensorless vector control, with built-in logic and PID processing, integrated diagnostics and modular communications support.
The 403 designation corresponds to a 3 hp (approximately 2.2 kW) constant torque drive suited to 380 to 480 V three phase systems. The H3 suffix denotes a standard panel mount unit supplied in a basic industrial enclosure rated IP20 / NEMA 1, intended for installation inside control cabinets rather than for harsher external environments.
