KJD17BD 120 Electromagnetic switch 120VAC, 18 Amp, 4 Pin, Waterproof Cover

Description:

The KJD17BD/120 Electromagnetic Switch is a heavy-duty magnetic pushbutton safety switch designed for reliable motor start/stop control on industrial machinery and power tools. Operating on 120 VAC with an 18 Amp (16 A inductive) rating, this 4-pin model features a waterproof protective cover and integrated no-volt release (NVR) protection to prevent accidental machine restart after a power failure. It is commonly used on table saws, drill presses, grinders, compressors, and other industrial equipment operating in dusty or damp environments.

Applications:

The KJD17BD/120 Electromagnetic Switch is used on woodworking machinery, metalworking equipment, bench grinders, air compressors, concrete mixers, and industrial machines requiring safe motor control. Its waterproof cover protects the pushbuttons from dust and moisture, while the magnetic holding circuit ensures the equipment remains off following a power interruption until manually restarted.
