Square D - 3 Pole, 600 VAC, 27 Continuous Amp, 5 hp, Enclosed NEMA Combination Starter - NEMA 1, RoHS Compliant, 30 Amp Short Circuit Protection

National Electrical Manufacturers' Association (NEMA) starters are electrically controlled switches used to rapidly open (break) and close (make) a circuit. They are larger than the International Electrotechnical Commission (IEC) starters and are considred more rugged and durable.

Enclosed housings are designed to ensure that the motor is never disconnected from power during starting. Ideal for frictional loads and prevention of electrical shocks and dust.

Three-phase refers to three individual lines (coils) that connect to and run voltage through the motor. Each line alternates in a sequence as they reach their voltage peak. They provide a more stable flow of voltage and more horsepower to the equipment.

Non-reversing starters are designed with one phase line that connects to and runs voltage through the motor. The starter is used to turn a motor on and off.
