Kevilton MCB Type Manual Changeover Switch (2 Pole / 4 Pole, 40A & 63A Ratings – Din-Rail Mounted Generator Transfer Switch)

⚡ Overview – Kevilton MCB Type Manual Changeover Switch

Are you looking for a reliable, compact, and safe way to switch your electrical supply between the main power grid and a backup generator?

Consequently, the Kevilton MCB Type Manual Changeover Switch offers seamless manual supply transfer in standard DIN-rail distribution boards. Designed with a robust mechanical interlock structure, it prevents simultaneous connection of both power sources, protecting your appliances and backup generator.

Furthermore, you can choose between 2 Pole (40A / 63A) for single-phase systems and 4 Pole (40A / 63A) for three-phase installations online in Sri Lanka with fast islandwide delivery.

⚡ Dual Supply Management & Safe Mechanical Interlock

First, this modular changeover switch provides complete safety during power transitions with a clear I-O-II center-off position.

In addition, the built-in mechanical interlock mechanism ensures that the main grid supply and the backup generator power can never engage at the same time. Thus, it eliminates dangerous short circuits, back-feeding into the grid, and power feedback surges.

As a result, electricians can safely route power between grid mains, solar inverters, or fuel generators with full mechanical safety.

🏢 Compact MCB Profile & Standard DIN-Rail Mounting

Additionally, upgrading your distribution panel with a generator switch has never been cleaner.

Specifically, it features a compact MCB profile design that snaps directly onto standard 35mm DIN-rails inside standard metal or PVC distribution boards. Consequently, you do not need to install large, bulky external rotary changeover boxes.

Furthermore, manufactured by Kevilton, Sri Lanka’s leading brand for electrical switchgear, it delivers long-lasting mechanical endurance and high arc-suppression safety.

🔋 Available in 2 Pole & 4 Pole (40A & 63A Options)

Furthermore, you can select the exact rating on elecshop.lk to match your home or industrial board:

• 2 Pole (40A & 63A): Ideal for single-phase residential wiring, switching Live and Neutral lines between grid and generator.

• 4 Pole (40A & 63A): Perfect for three-phase commercial buildings, switching 3 Phase lines + Neutral completely.

Finally, all Kevilton switchgear products conform to rigorous IEC and national electrical safety standards for ultimate reliability in Sri Lanka.

🤖 Recommended Usage Guidelines

First, select the correct pole configuration: 2 Pole for 230V Single-Phase homes or 4 Pole for 400V Three-Phase installations.

Next, mount the Kevilton switch directly onto the DIN-rail inside your distribution board near the main isolator.

After that, connect Source I (Grid Power) to the top input terminals, Source II (Generator/Inverter) to the bottom input terminals, and load lines to the output terminals as specified in the manual.

Finally, switch to the middle “OFF” position for a few seconds when changing power sources to protect sensitive electronics against voltage transients.
