KRIPAL UKX2-63 C/O Breaker 63A MCB

✅ Key Specifications & Features

• Rated current: 63A

• Rated voltage: ~ 400 V, 50/60 Hz.

• CE certified.

• Four terminal pairs (for changeover functionality) as per one source.

• Suitable for homes, shops and industries (per marketing description).

• ⚙️ What “Changeover Breaker” Means

  A changeover breaker (C/O) is used to switch the load between two sources (for example between utility supply and generator/alternate supply). The UKX2-63 appears to be designed for that purpose:

  • It likely has two input sources and one output load (or vice versa) and enables switching safely.

  • The “Four terminal pairs” suggests: two pairs for input sources, two pairs for output direction or load side.

  • Use case: when primary supply fails, you switch to alternate supply via the breaker (manual or automatic depending on design).

  • 📝 Practical Considerations

    • Install in a suitably rated enclosure (for 63 A load) and ensure the wiring and downstream protection match the breaker rating.

    • Confirm the switching mechanism: is it manual lever, or does it allow automatic transfer? The sources don’t specify “automatic transfer switch” functionality, just “changeover breaker”.

    • Since rated at ~400 V, ensure your system voltage is compatible (often 230/400 V in many installations).

    • Check manufacturer’s datasheet for breaking capacity (how high a fault current it can interrupt) — this is not clearly detailed in the sources I found.

    • Ensure correct wiring of both sources and outputs, and label clearly to avoid wrong source switching.
