63A DC Breaker for Solar Inverters | 2-Pole High Voltage Protection

Is your solar investment safe from sudden electrical surges?

The 63A DC Circuit Breaker from Pak ElectricCo is the essential safety gatekeeper for your solar panels and inverter, specifically engineered to handle the high-voltage demands of Pakistani solar setups.

Running a solar system in cities like Lahore, Multan, or Karachi means dealing with intense heat and occasional technical glitches. Without a dedicated DC breaker, a simple short circuit can fry your expensive inverter. Our 63A breaker acts as your first line of defense, cutting off power instantly if it detects a fault, saving you from lakhs in repair costs.

Why Choose the Pak ElectricCo 63A DC Breaker?

Unlike standard AC breakers that people mistakenly use for solar, this is a True DC Breaker. It is built to extinguish the “arc” that occurs in direct current, which is much more dangerous and persistent than AC.

Key Features & Specifications

• Rated Current: 63 Ampere (Ideal for 3kW to 10kW systems)

• Voltage Compatibility: Supports high DC voltages common in modern solar strings.

• Poles: 2-Pole (Double protection for both positive and negative lines).

• Material: Fire-retardant, high-grade plastic housing.

• Mounting: Standard Din-Rail mounting (Fits easily in any distribution box).

• Durability: Mechanical life of over 20,000 cycles.

How It Benefits You

• Inverter Longevity: By preventing over-current from reaching your inverter, you extend the life of your most expensive solar component.

• Fire Safety: Standard breakers can melt under DC loads. Our breaker uses specialized internal magnets to pull the electrical arc away, preventing fire hazards in your home or office.

• Peace of Mind: Once installed, you don’t have to worry about your panels during heavy rain or wind-induced short circuits.

• Zero Maintenance: Once fitted into your DB box, it requires no upkeep, just a simple monthly manual trip test to ensure it’s active.

Who Is It Perfect For?

This breaker is a must-have for:

• Homeowners with 3kW, 5kW, or 10kW solar systems.

• Shop Owners in busy markets who rely on solar for daytime backup.

• Offices looking to protect their sensitive IT equipment powered by hybrid solar.

Installation & Usage Guide

We recommend having this installed by a certified solar technician. It should be placed between the Solar Panels (PV) and the Inverter. Ensure the wires are tightened properly to avoid heating. For the best performance in Pakistan’s 45°C+ summers, ensure your distribution box has some ventilation.

Frequently Asked Questions (FAQ) – 63A DC Breaker for Solar Inverters | 2-Pole High Voltage Protection

1. Can I use a normal 63A AC breaker for my solar panels? No. AC breakers are not designed to stop DC arcs. Using an AC breaker for DC power is a major fire risk and may not trip when needed.

2. Is 63A enough for a 5kW solar system? Yes, for most 5kW and even 10kW strings, 63A provides a solid safety margin. Always check your panel’s short-circuit current (Isc) before final selection.

3. Does this breaker work with all brands of inverters in Pakistan? Absolutely. It is compatible with all major brands like Inverex, Tespack, Crown, and Knox.

4. Why is the breaker tripping frequently? If it trips often, it’s doing its job! It usually means there is a loose connection, a short circuit in your wiring, or your solar panels are producing more current than the system can handle.

5. Is there a warranty for this product? Yes, Pak ElectricCo provides a replacement warranty for manufacturing defects, giving you confidence in your purchase.
