The Eaton Cutler-Hammer S801U42N3S non-combination open soft starter is a 3-pole reduced voltage soft starter with standard duty ratings that is designed to provide a smooth start to 3-phase motors. The S801 soft starter family has a ‘soft stop’ option that allows for controlled motor stopping on high friction load applications, in addition to 3 other starting modes (the kick start, current limit, and ramp start). The S801U42N3S soft starter and every S801 soft starter helps to eliminate abrupt starts and stops that may damage machine components and extend the mechanical life of the system and reduce service costs. With the capacity to operate at 500 Amps maximum, this soft starter is ideal for high power applications with 200 to 600 Volts AC operating voltage (at 47 to 63 Hertz). The S801U42N3S soft starter has a standard duty rating of 100 Horsepower, and an insulation voltage rating of up to 660 Volts AC.

The S801U42N3S soft starter comes with add-on lug kit connectors for easy field wiring, and it can be installed easily by using the provided mounting plates. The S801U42N3S soft starter has multiple start modes for a wide range of applications, and it offers a soft stop option for high-friction load applications to prevent damage from sudden stops. It is built to function optimally in even the toughest environmental conditions, and it is designed to withstand a maximum operational shock of 15 G. It has an operating temperature range of -30 to 50 degrees Celsius, and it can be stored at a temperature between -50 to 70 degrees Celsius. The S801U42N3S soft starter has a net shipping weight of 48 pounds, and approximate mounting dimensions of 7.73 x 7.08 x 12.72 inches. It meets several industry standards such as the IEC 947, EN 60947-4-2, CSA, and CE standards.
