Circuit Breaker Types Pakistan 2026 — 8-Type Chart News
News — CNC Electric Pakistan, June 10, 2026.
Pakistani searches for "circuit breaker" averaged 1,300 monthly in 2026, with intent split across residential MCB / industrial MCCB / motor protection MPCB / RCBO. The full circuit breaker family has 8 distinct types and choosing wrong costs money and triggers Pakistani electrical inspection rejection. This news item explains the 2026 type chart, lists current Pakistani prices, and flags new NEPRA 2026 protection requirements that change which type you must use for solar net-metered installations.
Eight circuit breaker types — Pakistani 2026 market
| Type | Full name | Where used | Pakistani 2026 price (32A) PKR |
|---|---|---|---|
| MCB | Miniature Circuit Breaker | Residential sub-circuits, lighting, sockets | 425 - 1,650 |
| MCCB | Moulded Case Circuit Breaker | Commercial main distribution, industrial sub-feeders | 2,850 (40A) - 11,500 (100A) |
| ACB | Air Circuit Breaker | Main incoming > 800A, substation | 185,000+ (800A) |
| RCCB | Residual Current Circuit Breaker | Wet area, kitchen, bathroom, outdoor | 2,800 - 8,500 |
| RCBO | RCCB + MCB combined | NEPRA mandatory for solar + battery storage | 4,200 - 14,500 |
| MPCB | Motor Protection Circuit Breaker | Direct-online motor protection | 3,500 - 12,500 |
| SPD-integrated | Circuit breaker with Type 2 SPD | NEPRA mandatory for solar AC + DC sides | 5,800 - 15,500 |
| DC MCB / MCCB | DC-rated 250V / 500V / 1000V / 1500V | Solar PV string + battery DC bus | 1,850 - 9,500 |
Which "curve" (B / C / D / K) to specify
Beyond the breaker type, IEC 60898-1 specifies tripping curve based on inrush characteristics of the protected load:
| Curve | Magnetic trip range | Best for |
|---|---|---|
| B | 3-5× rated current | Resistive loads — lighting, geyser, oven |
| C | 5-10× rated current | Mixed loads — mainstream residential (most common in Pakistan) |
| D | 10-20× rated current | Motor starting, transformer inrush, capacitor banks |
| K | 8-12× rated current | Solar inverter inrush, UPS battery, welding plant |
NEPRA 2026 rule changes affecting breaker selection
- Type B RCBO is mandatory on AC + DC interfaces of all net-metered solar systems with battery storage (FY2026 effective)
- Type 2 SPD required on both DC and AC sides per IEC 61643-31
- DC MCB / MCCB rated to system DC voltage × 1.25 (1500V DC strings need 1500V-rated DC breaker)
- Curve C minimum for grid-tied inverter output; curve K recommended for hybrid + battery systems
- Annual trip test required on RCBO + RCCB for net-metered systems (record in maintenance log)
Pakistani buyer quick recommendation
- Standard 3-bed residential: Curve C MCBs in 12-way DB + RCCB main = PKR 12,500-22,000 fully-loaded
- Solar net-metered 5 kW system: Add Type B RCBO + Type 2 SPD + 1000V DC isolator = PKR 18,500-32,500 protection bundle
- Small factory 50 kW: MCCB main + Curve D motor branch + RCBO on sub-feeders = PKR 65,000-145,000
- Welding plant / VFD branch: Curve K MCB + detuned capacitor bank upstream = PKR 8,500-22,500
