Modular Contactor Kanlux KMC-25-31 25A 3 NO 1 NC 230V AC

Kanlux KMC-25-31 modular contactor is a DIN-rail mounted switching device designed for electrical installations that require compact, rail-mounted control of AC loads. With a 25 A switching capacity and a 230 V AC coil, it offers three normally open contacts and one normally closed contact to manage lighting circuits, small motors and other low-voltage AC loads in both residential and light commercial environments.

Advantages

The modular design allows straightforward DIN-rail installation and saves panel space compared with traditional contactors. Having three normally open and one normally closed contact provides flexible wiring options for multi-circuit control. The 25 A rated switching capacity covers a wide range of lighting and small motor loads while the 230 V AC coil ensures direct compatibility with common mains supplies. The device is built for reliable switching cycles in typical building automation and electrical distribution applications.

Suitable for

• Controlling residential and commercial lighting circuits
• Switching small motors and pumps within rated current
• Integration into DIN-rail distribution boards and automation panels
• Centralized switching of multiple circuits from one module

Key specifications

• Rated switching current: 25 A
• Coil voltage: 230 V AC
• Contact configuration: 3 normally open (NO) + 1 normally closed (NC)
• Mounting type: DIN-rail modular housing
• Intended application: AC loads such as lighting and small motors

How to use

Mount the contactor on a standard DIN rail inside a distribution or control panel. Connect the supply voltage to the coil terminals rated for 230 V AC and wire load circuits to the NO and NC contacts according to the required control logic. Ensure conductors and protective devices are selected to match the 25 A switching capacity and local electrical regulations. Use appropriate auxiliary protection and coordination with upstream breakers or fuses to safeguard the installation.

Usage recommendations

Verify compatibility of the contactor with the connected load types and ensure that inrush currents (for example from motors or certain lamp types) do not exceed the device's switching capacity. Periodically inspect terminal connections for tightness and signs of wear. For installations with critical loads, provide additional overload protection or contactor grouping as required by local standards.
