Overview

The NMCPSD control and protection switch is the main switch, combined with accessories such as contactors to form a two-speed motor controller NMCPSD, which is used for control and protection of two-speed motors.

Product features, main circuit parameters and accessories are the same as NY-KBO standard.

When the motor is used as an exhaust fan, the NMCPSD switch operates and the motor runs at a low speed;

When the motor is used as a exhaust fan, the NMCPSD switch and the KM AC contactor operate, and the motor runs at high speed, either on-site or remotely.

There are three types of two-speed motor controllers that do not trip according to the jump:

Configuration one: high speed for fire type (overload, over current only alarm does not trip), low speed is basic:

Configuration 2: Both high and low speed are basic;

Configuration 3: Both high and low speed are fire type (special order should be indicated).

Product features, main circuit parameters and accessory modules are the same as basic models.

There are three types according to the current: (145 type + 45 type; 245 type + 125 type; 3125 type + 125 type)
