An inductive load that pulls several times its running current to start — protection has to allow for that.
An inductive load that pulls several times its running current to start — protection has to allow for that.
Defined in the glossary — each one opens at its own entry.
Motors are hard to start and easy to stall: starting current is typically six times the running current, and a stalled motor draws that continuously until the overload trips. Protection must be sized so the motor starts without nuisance tripping while still clearing a stall — and the frame must be earthed. Always isolate, and remember the capacitor can hold a charge after switch-off.
Set Electric Motor into a live circuit, inject a fault, and watch the protection respond — all in your browser.
