Danfoss MCD3132-T5-C21 Soft Starter

Feature & Principle

It is Danfoss MCD3000 series compact soft starter. It adopts three-phase anti-parallel thyristor regulation to smoothly adjust output voltage, limit starting inrush current and reduce mechanical shock of the motor. Built-in multiple protection functions, with local operation panel for parameter setting and fault checking. C21 stands for IP21 compact version, suitable for direct cabinet wall mounting. This model is discontinued, used for maintenance replacement of water treatment, HVAC and industrial fan loads.
