Modular Contactor Kanlux KMC-20-40 20 A 4 NO 0R 230 V AC (model 23241)

Modular Contactor Kanlux KMC-20-40 is a DIN-rail mount switching device designed for centralized control of electrical circuits in residential and commercial installations. Rated for 20 A with four normally open (4 NO) main contacts and a 230 V AC coil, this contactor enables remote switching of lighting, heating, motors and other auxiliary loads. Its compact modular form factor fits standard distribution boards and is intended for use where reliable, repeated switching of inductive and resistive loads is required.

Advantages

The Kanlux KMC-20-40 offers a compact modular design suitable for DIN-rail mounting, reducing panel space requirements while providing straightforward integration into control systems. With four independent normally open contacts it allows simultaneous switching of multiple circuits from a single control signal. The 230 V AC coil is compatible with common mains control voltages, and the device is built to handle both resistive and inductive loads at the specified 20 A rating, delivering stable performance in frequent switching applications.

Suitable for

• Centralized switching of lighting circuits in apartments, offices and public buildings
• Control of electric heating zones and circulation pumps
• Switching of small motors and fans in HVAC or ventilation systems
• Integration in automation and control panels for auxiliary loads

Key specifications

• Rated operational current: 20 A
• Contact configuration: 4 normally open (4 NO) main contacts
• Coil control voltage: 230 V AC
• Mounting type: DIN-rail modular housing
• Intended load types: resistive and inductive loads (lighting, motors, heating)

How to use

Install the modular contactor on a standard DIN-rail inside a distribution or control panel according to local electrical codes. Connect supply and load conductors to the appropriate main contact terminals and wire the 230 V AC control coil to the control circuit. Ensure conductor cross-sections and protective devices match the contactor's 20 A rating and the characteristics of the connected loads. Verify correct operation by applying the control voltage and observing switching of the intended circuits before full commissioning.

Usage recommendations

Use protective devices such as circuit breakers or fuses sized and coordinated with the contactor's rated current and the connected load. For inductive loads, consider appropriate suppression or inrush current management to extend contact life. Follow national wiring regulations and consult the manufacturer's installation instructions for torque settings and connection details.
