What the VFD037E43T is on the BOM line
The VFD037E43T is a Delta VFD-series inverter drive sized for a 5 HP (3.7 kW) motor on a 460 V three-phase mains supply, built in the Frame A chassis with an integrated brake chopper for dynamic-stop resistor switching.
Motor sizing and brake-chopper fit
The 037 code in the part number maps directly to the 5 HP / 3.7 kW motor rating, which is the figure that drives the breaker, contactor, and reactor sizing upstream — not the headline frame size. The T suffix marks Frame A with a built-in brake chopper, which matters on any application with a fast deceleration profile — conveyors lowering product, vertical axes, or centrifuges spinning down — because the chopper dumps regen energy into an external resistor before the DC bus trips on overvoltage. The 460 V three-phase input range lets the same drive land on the 380–460 V industrial rails common in light-heavy manufacturing and process skids, so a panel wired for 460 V doesn't need a step-down transformer to accept the VFD037E43T.
Production status and sourcing reality
For plants standardizing on a single drive family, the VFD022E43T sits one size down at 3 HP (2.2 kW) on the same Frame A chassis and shares the brake-chopper option, so a fleet decision between the two is a motor-horsepower call rather than a panel-footprint or wiring change.
Sourcing the VFD037E43T through independent distribution
Active VFD-E series stock moves through independent distribution on a quoted-to-order basis — the lead-time band is 1–10 working days, so a maintenance planner can hold a spare without committing to factory-direct minimum order quantities. Submit the RFQ with the motor horsepower and the panel voltage code so the quote lines up the right Frame A variant; the part number itself encodes both the 5 HP rating and the 460 V three-phase input class, which removes the usual ambiguity on cross-reference requests.
