Switch-disconnector fuse 63A 3-pole Kanlux KSF02-63-3P (23343)

Kanlux KSF02-63-3P is a 3-pole switch-disconnector fuse rated at 63 A, intended for safe manual isolation and overcurrent protection in three-phase electrical circuits. Built for installation in distribution boards and switchgear, it provides a visible disconnection point and accepts replaceable cartridge fuses to enable quick fault clearing and maintenance without altering the wiring layout.

Advantages

The switch-disconnector offers clear mechanical isolation for three poles with a 63 A current rating, combining disconnection and fuse protection in a single compact device. Its design supports routine maintenance and rapid replacement of cartridge fuses, and it is suitable for mounting in standard panel locations. The unit contributes to safer service operations by providing a distinct ON/OFF position and an accessible fuse carrier.

Suitable for

• Isolation and overcurrent protection of three-phase circuits in small commercial or residential distribution boards
• Protection of branch circuits supplying motors, heaters, or other 3-phase loads up to 63 A
• Use as a local disconnecting device for maintenance and troubleshooting

When it may not be suitable

This switch-disconnector is designed for manual operation and 63 A-rated circuits; it is not suitable where higher continuous currents or remote/automatic switching are required. It also requires compatible cartridge fuses of the correct type and rating—without the correct fuses installed the device cannot provide proper overcurrent protection.

Key specifications

• Poles: 3-pole configuration for three-phase circuits
• Rated current: 63 A
• Function: Combined switch-disconnector with fuse carrier for replaceable cartridge fuses
• Mounting: Intended for distribution board or panel mounting
• Operation: Manual ON/OFF disconnection with visible isolation

How to use

Install the device in the distribution board following local electrical regulations and ensure correct tightening of terminals for reliable contact. Fit appropriate cartridge fuses that match the required breaking capacity and characteristic for the protected circuit. Operate the handle to isolate the circuit during maintenance, and replace blown fuses only after locating and remedying the fault. Always switch off upstream supply and confirm absence of voltage before servicing.

What to consider before purchase

• Confirm that a 63 A rated switch-disconnector meets the continuous current demands of the circuit
• Verify compatibility with the distribution board dimensions and mounting type
• Ensure availability of compatible cartridge fuses with suitable breaking capacity and characteristics
• Check applicable local standards and installation regulations for switch-disconnector devices

Usage recommendations

Use the switch-disconnector for manual isolation in three-phase circuits where visible and reliable disconnection is required. Pair it with cartridge fuses selected to match the load characteristics and fault current levels, and schedule regular visual inspections to confirm tight connections and proper operation.
