Eaton 014557

The T0-5-15900/E Star-delta switch features a maintained actuator with a 0 (Off) position. It is configured with nine contacts and operates at a switching angle of 60°. The dimensions of the switch are 114 mm in length, 48 mm in height, and 48 mm in width, with a weight of 0.147 kg. This switch is capable of handling a rated operational current of 20 A at AC-3, and offers various motor power ratings depending on the supply voltage, including up to 7.5 HP for 460/480 V three-phase applications.

For its environmental resistance, the switch meets the requirements for corrosion resistance and thermal stability, suitable for ambient temperatures ranging from -25 °C to 50 °C. The enclosure is made of plastic and has a degree of protection rated at IP65 and NEMA 12, making it appropriate for damp environments. It is designed to endure mechanical shocks of 15 g and has a lifespan of approximately 400,000 operations.

Compliance with several standards is ensured, including IEC/EN 60947 and UL 60947-4-1. The short-circuit rating is specified at 6 kA, with a rated short-time withstand current (Icw) of 320 A for one second. This switch is engineered to facilitate the control of motor circuits, making it suitable for various industrial applications.
