ODM SJKCPS Control and Protective Switching device Factory, Company

The Control and Protective Switching Device (CPS) integrates motor control and circuit protection in one compact unit, supporting 0.4-125A adjustable overload ranges for AC380-400V/50-60Hz systems. This CPS combines electronic trip functionality with utilization categories AC-42/43/44, enabling precise motor management for pumps, fans, and compressors. With 80V control power compatibility (0.12-55kW) and modular design, the SJKCPS series simplifies installation while providing reliable short-circuit and overload protection. Ideal for industrial automation, this control and protective switching device reduces wiring complexity and enhances system safety.

Basic Model Operation Panel Diagram and Installation Dimensions

1. Control (Automatic or Manual) Position:

In this state, the internal control coil contact is in the closed position, controlling the circuit through the coil control circuit for remote automatic control.

2. Free Release Position:

The position where both main contacts and electromagnetic coil control contacts are disconnected due to faults like overload, short circuit, or phase loss.

3. Disconnection Position:

Both the coil contact and the SJKCPS main contact are in the disconnected position.

4. Re-engagement Position:

The switchgear can only be freely released when the knob is turned to this position, allowing for normal resetting.

Frequently Asked Questions

What functions does the SJKCPS integrate? The SJKCPS series integrates control and protection functions into a single switching device, capable of handling motor protection and power distribution with various trip adjustments.

What are the available frame current ratings? The device is available in two main frame current ratings: 45A and 125A, covering a wide range of operational currents from 1A up to 125A.

How do I reset the device after a fault trip? After a free release due to a fault, the operating knob must be turned to the "Re-engagement Position" to reset the mechanism before it can be closed again.

Is the SJKCPS suitable for fire protection systems? Yes, the "F-Fire Protection Type" is specifically designed to provide an alarm signal only without tripping the circuit, ensuring continuous power in emergency scenarios.

What load types can this switchgear control? It supports both Motor (M) and Power Distribution (P) load types, with utilization categories including AC-42, AC-43, and AC-44 for various induction motor applications.
