Product Description
Outdoor Rated DC Circuit Breaker - 2P 63A, IP65 Waterproof, 500V/1000V DC
- 2-Pole (2P) Design: Switches both positive (+) and negative (-) conductors - complete isolation for DC circuits.
- 63A High Current Capacity: Ideal for solar PV strings, combiner boxes, and battery disconnects.
- IP65 Waterproof Enclosure: Dust-tight and protected against low-pressure water jets - perfect for outdoor installation in rain, snow, or dust.
- DC500V or DC1000V Optional: Choose the voltage rating that matches your solar array (500V for smaller systems, 1000V for modern high-voltage PV).
- Built-for-DC Arc Extinction: Special arc chutes designed for DC circuits - safe and reliable.
- Thermal-Magnetic Protection: Overload and short-circuit protection for your PV system.
- Clear ON/OFF Indicators: Visual confirmation of breaker status.
Solar photovoltaic (PV) systems require robust DC circuit protection that can withstand outdoor conditions. The 2P 63A DC Circuit Breaker is specifically designed for DC applications up to 1000V and 63A, housed in an IP65 waterproof enclosure for direct outdoor mounting.
Whether you need a disconnect for a solar combiner box, a battery bank, or an array isolation switch, this 2-pole (2P) breaker switches both positive and negative conductors, providing complete disconnection. The IP65 rating means it is dust-tight and protected against low-pressure water jets - rain, snow, hose-down, and dusty environments are no problem.
Available in 500V DC (for smaller residential arrays) or 1000V DC (for modern high-voltage strings), you can choose the correct voltage rating for your system. The built-in thermal-magnetic trip mechanism protects against overloads and short circuits, with arc chutes specially designed to extinguish the continuous DC arc.
Ideal for:
- Solar PV combiner boxes - string overcurrent protection.
- Array disconnect switches - isolation between panels and inverter.
- Battery banks - DC disconnect for charge/discharge circuits.
- Outdoor air switch applications - weatherproof safety disconnect.
- Off-grid and hybrid solar systems.

Frequently Asked Questions
What is the main application of this 2P DC circuit breaker?
This 2-Pole 63A DC circuit breaker is mainly used for solar PV combiner boxes, array disconnect switches, battery bank protection, and outdoor safety isolation in off-grid or hybrid solar power setups.
Does this DC circuit breaker come with a waterproof enclosure?
Yes, it is pre-housed in an IP65-rated waterproof distribution box, making it highly dust-tight and safe from rain, snow, and low-pressure water jets during outdoor installations.
Can I use this breaker for systems up to 1000V?
Yes, we offer both DC500V and DC1000V specifications. Please choose the voltage rating that matches your system configuration for optimal overcurrent and short-circuit protection.
Why is a 2-Pole (2P) configuration important for DC solar systems?
A 2-Pole breaker disconnects both the positive (+) and negative (-) lines simultaneously, ensuring complete isolation of the DC power source for maximum safety during maintenance.
What is the operating temperature range for this product?
This circuit breaker is designed to operate reliably in harsh environmental conditions, with a tested temperature range of -25°C to +55°C.
What size wire can the terminals accommodate?
The high-quality terminals are capable of accepting wiring capacities up to 16mm², allowing robust connection security for your solar components.
