Modular Switch 63A 3P Kanlux KMI-3/63A (model 23233)

The Kanlux Modular Switch 63A 3P KMI-3/63A is a three-pole manual isolator designed to disconnect and isolate three-phase electrical circuits rated up to 63 amperes. Intended for installation in distribution boards, this modular switch provides a clear mechanical separation for maintenance and fault isolation in residential, commercial and light industrial electrical systems. Its compact modular form factor fits standard DIN-rail enclosures and is suitable where a reliable 63A three-pole switching device is required.

Advantages

This modular switch offers straightforward manual operation with a visible switching position for easy verification of circuit status. The device is built to provide safe isolation of all three phases simultaneously, reducing the risk during service and troubleshooting. Its modular design allows integration into common consumer units and distribution boards, saving panel space while maintaining reliable switching capability for three-phase loads up to 63 A.

Suitable for

• Isolation of three-phase supply circuits in residential distribution boards
• Switching and maintenance isolation in small commercial electrical panels
• Light industrial machinery or sub-circuits requiring a 63 A three-pole isolator
• Service and safety isolation during installation, repair and testing

When it may not be suitable

This device is a manual isolator and does not provide overcurrent protection by itself; it should be used in conjunction with appropriate circuit breakers or fuses sized for the installation. It is not intended for switching loads above its 63 A rating or for direct switching of highly inductive loads without proper coordination with protective devices. For applications requiring remote control, automatic tripping, or integrated protection functions, a different product that includes those features should be selected.

Key specifications

• Poles: 3 (three-phase isolation)
• Rated current: 63 A
• Mounting: Modular/DIN-rail compatible
• Operation: Manual mechanical switching with visible contact position
• Application environment: Indoor distribution boards for residential, commercial, and light industrial use

How to use

Install the modular switch on a standard DIN rail inside the distribution board according to local electrical regulations and wiring diagrams. Connect the three incoming phase conductors to the line terminals and the outgoing phase conductors to the load terminals, ensuring all connections are tightened to the manufacturer's recommended torque. To isolate the circuit, move the switch lever to the off position; verify the visible indicator shows an open contact. Always de-energize and test the circuit before performing work and use appropriate personal protective equipment.

What to consider before purchase

• Verify the three-phase supply and load currents do not exceed 63 A.
• Ensure compatibility with your distribution board's modular width and DIN-rail mounting.
• Plan complementary protective devices (circuit breakers/fuses) as this switch does not provide overcurrent protection.
• Confirm required certifications and local regulatory compliance for installation.

Usage recommendations

Use the Kanlux KMI-3/63A as a dedicated manual isolator for three-phase circuits together with appropriately rated protective devices. Periodically inspect terminal tightness and the visible switching indicator as part of routine maintenance to ensure continued safe operation.
