The Hager MTN163 is a 63A B curve single pole miniature circuit breaker with 6kA rated short-circuit breaking capacity in a compact 1 module DIN rail body. It is a current Hager MTN device for suitable board layouts where the circuit design requires a 63A MCB.

• 63A rated current with B curve tripping characteristic
• 6kA rated short-circuit breaking capacity to IEC 60898-1
• Single pole 1P format in a 1 module body
• 230 to 400V AC rated operational voltage and 50 to 60Hz frequency
• Screw terminal top connection and biconnect bottom connection
• 70mm depth, 17.5mm width and 83mm height
• IP20 protection with 1 to 35mm² rigid and 1 to 25mm² flexible conductor capacity

When should the 63A rating be used?

MTN163 should be selected only where the circuit design and board arrangement support a 63A single pole MCB. It is not a casual replacement for a lower-rated device and must be checked against conductor size, load and installation conditions.

What are the main limitations?

This is an MCB only. It does not provide 30mA residual-current protection, so the installer must confirm the RCD or RCBO arrangement required for the circuit and connected equipment.

Why keep this as a page even if stock is limited?

MTN163 is current on Hager’s UK catalogue, and exact searches for Hager MTN163 or Hager 63A B curve MCB need a proper product destination. Mark the live page according to actual availability rather than deleting a current range item.
