Description

CNC YCB7-63N 3 Pole MCB — 16A to 63A

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.

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.

Specifications

Model YCB7-63N (3P)
Poles 3 Pole
Rated Current 16A, 20A, 32A, 40A, 63A
Rated Voltage AC 400V / 50Hz
Breaking Capacity 6kA
Trip Curve C Curve
Mounting 35mm DIN Rail
Standard IEC 60898

Typical Uses

  • Three-phase motor protection (up to roughly 15 HP at 63A)
  • Sub-main breaker in 3-phase distribution boards
  • 3-phase air conditioning compressor feeder
  • Three-phase water pump starter panel
  • Small workshop machinery protection

Sizing Tip

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.
