AC 3 Pole MCCB 32A, 40A, 63A, 100A, 125A, 160A, 200A, 250A, 400A, 630A, 800A, 1000A, 1250A | Reliable Protection

Looking for an AC MCCB 3 pole breaker price in Pakistan for a commercial panel, industrial feeder, motor application, or building main distribution board? This CNC Electric YCM7 molded case circuit breaker is built for users who need more serious protection than a small MCB can provide. In Pakistan, once a circuit moves into larger motors, heavier feeders, generator-backed panels, or commercial distribution work, an MCCB breaker becomes the more practical choice. For electricians, panel builders, facility managers, and industrial users, this 3 pole MCCB gives a stronger protection class for overload, short circuit, and under-voltage related panel design needs.

Key Features

• 3 pole molded case circuit breaker for AC distribution and motor-protection applications where a normal small breaker is not enough.
• Full local selling range from 32A to 1250A across six YCM7 frame groups — covers light commercial boards all the way to heavy industrial incoming mains.
• Designed for AC 50Hz networks with rated insulation voltage 800V according to the live product description.
• Rated voltage values are AC400V / AC690V across all frame groups.
• Thermo-magnetic automatic tripping device gives it practical protection logic for overload and short-circuit faults.
• Vertical and horizontal installation are both supported, which helps in real panel-building work.
• Strong short-circuit interrupting ability and low arc-energy behavior for safer industrial and commercial panel use.
• Built to IEC 60947-2 molded-case breaker context for low-voltage switchgear protection devices.

Product Range & Prices

Applications

• Commercial building main and sub-distribution boards where feeder current has moved beyond normal MCB territory.
• Industrial panels in Lahore, Karachi, or Faisalabad where motor circuits, process loads, and larger feeders need molded-case protection.
• Solar and backup-power related AC distribution panels where the incoming or outgoing circuit is too heavy for a small modular breaker.
• Generator and ATS panels where larger current paths need stronger breaker logic and clearer short-circuit performance than MCB-class devices.
• Motor-protection jobs where overload, short-circuit, and under-voltage protection are relevant to the system design.
• Panels that also need SPD, Voltage Protectors, and organized DB or enclosure planning.

Sizing / Selection Guide

Choose this YCM7 range when the circuit needs a molded-case breaker rather than a small MCB. The main checks are feeder current, fault level, whether the load is distribution or motor-focused, and whether the breaker is being used as an incoming main, outgoing feeder, or machine supply breaker.

• 32A–125A — smaller commercial boards, light industrial feeders, and compact power-distribution jobs. Rs.4,400–Rs.5,500.
• 160A–250A — heavier commercial feeders, workshop panels, mid-size motor circuits. Rs.8,000–Rs.11,000.
• 400A–630A — large industrial feeders, heavy-duty motor circuits, major distribution sub-mains. Rs.30,000–Rs.40,000.
• 800A–1250A — incoming mains, heavy-duty service protection, major panel incomers. Rs.53,000–Rs.87,000.
• Build the full panel correctly with the right SPD, contactor or overload logic where relevant, and proper cable sizing instead of sizing the breaker in isolation.

AC MCCB vs Alternatives — Why CNC?

For Pakistani buyers, the real comparison is not just MCCB brand versus MCCB brand. It is MCCB versus undersized MCB practice, and proper feeder protection versus overloading a modular solution that was never meant for the job. That is why a molded-case breaker like this stays important in serious panel work.

What This Product Does NOT Protect Against

• It is not an SPD and does not replace surge protection for sensitive panels or electronics.
• It is not a Voltage Protector and should not be used as the only answer for unstable mains conditions.
• It does not fix poor cable sizing, weak busbar design, bad earthing, or careless panel workmanship.
• It should not be selected only by current rating without checking the actual fault level and panel design conditions.
• It does not replace overload relays or contactor logic where a motor starter arrangement needs separate coordinated devices.

Installation Guide

1. Confirm the circuit is genuinely a 3-phase application and that the selected current rating matches the feeder or motor duty.
2. Install the MCCB inside a properly designed panel with correct cable lugs, busbar spacing, and enclosure support.
3. Use the correct incoming and outgoing conductor size so the breaker is not paired with undersized cabling.
4. Mount vertically or horizontally according to the panel layout — both installation directions are supported.
5. Commission the panel under controlled conditions and verify trip coordination with the rest of the protective devices.
6. Finish the installation with SPD, proper enclosure planning, and the Fire Extinguisher Guide.

FAQs

What is an AC 3 pole MCCB breaker?

It is a molded case circuit breaker used on three-phase AC systems where the circuit current and fault conditions are heavier than normal small-breaker applications.

What is the 3 pole MCCB price in Pakistan?

The YCM7 3-pole MCCB is priced from Rs.4,400 for the 32A and 40A variants up to Rs.87,000 for the 1000A and 1250A frames. See the full variant table above for each amp rating.

Can this MCCB be used for motors as well as power distribution?

Yes. It is used for both electric-energy distribution and motor protection against overload, short circuit, and under-voltage faults.

What voltage class does this YCM7 MCCB support?

AC400V / AC690V rated voltage and AC800V insulation voltage across all frame groups.

Is this better than using an MCB on a large feeder?

Yes. Once the load and panel duty move beyond small-breaker territory, an MCCB is usually the more correct protection class for larger feeders.

Can it be installed both vertically and horizontally?

Yes. Both installation directions are supported by this breaker.

Does this MCCB include surge or voltage protection?

No. It is a molded-case breaker. Surge control still requires SPD, and unsafe voltage management may still need a Voltage Protector.

What short-circuit breaking capacity does it have?

Short-circuit capacity ranges from 15/8 kA through 50/35 kA at AC400V, depending on the frame group (YCM7-125S through YCM7-800M).

How do I choose the right current rating in this MCCB family?

Choose it from the actual feeder current, motor duty if relevant, cable size, and overall panel design. Do not choose only by the visible price or by copying a nearby project.

What should I add with this MCCB for a better panel?

A better-finished panel usually includes the right contactors where relevant, SPD, voltage protection, sound enclosure planning, and nearby panel fire protection.

If you need a practical 3 pole MCCB in Pakistan for real feeder and motor protection work, this CNC Electric YCM7 line is a strong commercial option. It gives you molded-case protection logic, clear per-amp pricing from Rs.4,400 to Rs.87,000 across 13 current ratings, and the kind of flexibility that suits commercial and industrial panel work far better than forcing an undersized breaker approach.
