CNC YCB7-63N 3 Pole MCB — 16A to 63A<\/h2>\n

A three-pole miniature circuit breaker for three-phase circuits without neutral. The YCB7-63N 3P protects three-phase motors, compressors, and distribution feeders against overload and short circuit — standard equipment in Pakistani industrial and commercial panels.<\/p>\n

Unlike the 4-pole version, this 3P MCB does not include a neutral pole. Use it where neutral is handled separately (busbar) or where the load does not need a switched neutral, such as 3-phase motor circuits.<\/p>\n

Typical Uses<\/h2>\n
    \n
  • Three-phase motor protection (up to roughly 15 HP at 63A)<\/li>\n
  • Sub-main breaker in 3-phase distribution boards<\/li>\n
  • 3-phase air conditioning compressor feeder<\/li>\n
  • Three-phase water pump starter panel<\/li>\n
  • Small workshop machinery protection<\/li>\n<\/ul>\n

    Sizing Tip<\/h2>\n

    For motor protection, pick a C-curve MCB rated at 1.25x the motor full-load current. A 10 HP motor drawing about 19A on 3-phase 400V should use the 32A variant. For lighting or resistive loads, the 20A or 32A covers most commercial panels.<\/p>\n","protected":false},"excerpt":{"rendered":"
