※ Overview
The SD series universal soft start control cabinet is an intelligent typeSoft starterA single motor control device that integrates the main control components with fast fuses, main circuit breakers, bypass contactors, and motor thermal relays, and can achieve multiple protections.
※ Control function
The control device (with an optional all digital soft starter) is equipped with start and stop buttons, as well as operation, stop, and fault indicators. The device is equipped with remote control contacts, which include start and stop input contacts, operation indication output contacts, and fault output contacts (all passive relay contacts). It has functions of short circuit protection, overload protection, overheating protection, and phase failure protection.
