In Pakistan, solar energy systems and battery-powered setups are booming—from home solar installations to commercial backup solutions. At the heart of these systems lies a critical component: the DC breaker. Designed to protect circuits from overloads, short circuits, and battery damage, DC breakers are non-negotiable for safety. But with prices ranging from ₨1,250 to ₨9,500, how do you pick the right one without overspending?
In this guide, we’ll break down Pakistan’s DC breaker market, including typical prices, key specs, and how to match your needs to the right model. We’ll also share insights into popular brands (like TOMZN, Earu, and Taxnele) and why trusted names like CNC are a top choice for reliability and value.
DC Breaker Prices in Pakistan: Key Models & Ranges
Pakistan’s DC breaker market offers options for every budget, with prices driven by current rating (amps), voltage (volts), number of poles, and application (solar, battery, etc.). Below are typical price ranges based on real 2025 listings:
1. 125A DC Breakers (Most Common for Home/Business Use)
Ideal for mid-sized solar systems (5–10kW) or battery banks powering appliances like fans, lights, or small inverters:
- 1P (Single Pole): ₨1,250–₨1,650 (e.g., Earu solar DC breaker: ₨1,250; 1P 500V battery breaker: ₨1,650).
- 2P (Double Pole): ₨2,200–₨2,550 (e.g., Earu 2P 125A battery breaker: ₨2,200; Taxnele 2P 1000V breaker: ₨2,550).
2. 250A DC Breakers (Heavy-Duty Industrial/Solar Use)
For large solar farms (20kW+) or commercial battery systems powering heavy loads like AC units or machinery:
- 2P 500V–1000V: ₨6,700–₨9,500 (e.g., TOMZN 2P 250A solar MCCB: ₨9,500; TOMZN 125A 2P breaker: ₨6,700).
3. Budget-Friendly Basic Models
For small-scale projects like RVs, off-grid cabins, or low-power battery backups:
- 1P 125A–250A: ₨1,400–₨1,700 (e.g., Tomzn basic solar DC breaker: ₨1,700; TOMZN 1000V MCB: ₨1,400).
Why Prices Vary: 5 Factors That Impact Cost
Understanding what drives prices helps you avoid overpaying for unnecessary features:
1. Current Rating (Amps)
Higher amps (e.g., 250A vs. 125A) mean thicker internal wiring and better heat dissipation—critical for heavy loads. A 250A breaker (₨9,500) costs 5x more than a 125A model (₨1,700).
2. Voltage Rating (Volts)
DC systems often run at 500V or 1000V. A 1000V breaker (e.g., Taxnele 2P 1000V: ₨2,550) is pricier than a 500V unit (₨2,200) due to better insulation.
3. Number of Poles
- 1P: Protects a single circuit (common for small battery banks).
- 2P: Protects two circuits simultaneously (ideal for solar inverters with dual inputs).
A 2P breaker (₨2,200) costs 30% more than a 1P model (₨1,650).
4. Brand & Quality
Premium brands like TOMZN invest in durable materials (silver-plated contacts, fire-resistant casing) and testing, justifying higher prices (e.g., TOMZN 250A breaker: ₨9,500 vs. generic 250A: ₨7,000).
5. Application-Specific Design
Solar-specific breakers (with surge protection for inverters) cost more than generic battery breakers. For example, a Taxnele solar DC breaker (₨1,500) is 20% pricier than a basic 1P battery breaker (₨1,250).
How to Choose the Right DC Breaker in Pakistan
Follow these steps to match your system’s needs and budget:
Step 1: Identify Your Application
- Home solar (5–10kW): A 125A 2P breaker (₨2,200–₨2,550) works for most setups.
- Commercial solar (20kW+): Invest in a 250A 2P breaker (₨6,700–₨9,500) for heavy loads.
- Battery backups (RVs, cabins): A budget 1P 125A breaker (₨1,250–₨1,700) suffices.
Step 2: Calculate Your Load
Check your system’s total current draw. For example:
- A 5kW solar system (12V battery) draws ~417A (5000W/12V). A 250A breaker is too small—opt for a 400A model (not listed, but adjust based on your setup).
Step 3: Match Voltage & Poles
- 500V systems (common in home solar): Use 500V-rated breakers (e.g., TOMZN 125A 500V: ₨6,700).
- 1000V systems (industrial solar): Choose 1000V breakers (e.g., Taxnele 2P 1000V: ₨2,550).
Step 4: Trust Reputable Brands
CNC, for instance, offers a sweet spot of quality and affordability:
- Solar-specific designs: Their 125A 2P breaker (₨2,400) includes surge protection for inverters.
- Durability: Silver-plated contacts resist corrosion—critical for Pakistan’s humid climates.
- Warranty: Most CNC models come with 1–2 years of coverage, beating generic options.
FAQ: Common Questions About DC Breakers
Q: Can I use an AC breaker for DC circuits?
A: No. DC breakers have different arc-quenching mechanisms—AC breakers can fail to cut power in DC systems, risking fires.
Q: How long do DC breakers last?
A: Basic models last 5–7 years; premium brands like CNC or TOMZN last 10+ years with proper maintenance.
Q: Do I need an electrician to install it?
A: Yes. DC circuits carry high current—improper installation risks shocks or system damage. Always hire a certified technician.
Q: What’s the difference between MCCB and MCB?
A: MCCB (Molded Case Circuit Breaker) handles higher currents (100A+), while MCB (Miniature Circuit Breaker) is for lower currents (1A–63A). For solar/battery systems, MCCBs are more common.
Final Thoughts: Invest in Safety
DC breakers are the unsung heroes of solar and battery systems—they protect your investment and prevent disasters. By matching your load, voltage, and application to the right model, you’ll avoid overspending while ensuring reliability.
