The S511 device is a Semiconductor (Solid-State) Reversing Contactor designed to switch 3-phase motors forward and reverse. Unicore electronics and thermal design ensures high switching capacity and long lifetime.
Application Description
The S511 line of solid-state reversing contactors is specifically designed for high speed operations or when long contactor life is required. The reversing contactors are intended for small motor applications (5 hp and below). The S511 unit can be used in a variety of applications including fans, pumps, conveyors, doors, hoists, cranes, etc. It is designed to be used with a Manual Motor Starter or a full voltage starter. These devices provide the necessary overload protection for the motor and also provide line isolation for the motor. Short-circuit protection can be provided by fuses or circuit breakers.
