Using HYCI as a switch, combined with accessories such as contactors and electrical interlocks, it constitutes the dual-speed electric controller HYCID, which is suitable for the control and protection of dual-speed electric motors. There are three configurations for dual-speed motor controllers:

Configuration 1: High speed is fire-fighting type (overload and overcurrent only alarm without tripping), low speed is basic type.

Configuration 2: Both high speed and low speed are basic types

Configuration 3: Both high speed and low speed are fire-fighting types (special order should be indicated)

Product features, main circuit parameters and accessories, modules are the same as the basic type
