Suntree Dc Breaker 32A 2P Double Pole
The Suntree DC Breaker 32A 2P Double Pole is a purpose-built direct current circuit breaker designed to protect solar photovoltaic systems, battery storage solutions, and off-grid power installations. With a voltage rating of up to 550V DC and a current rating of 32 amps, it is suitable for high-voltage solar installations, while the 2-pole configuration allows for two separate circuits to be protected simultaneously. Solar Shop Africa Compact, reliable, and DIN rail mountable — it is the trusted choice for solar installers and electricians across Kenya.
Why Choose the Suntree DC Breaker 32A 2P?
Solar DC circuits present unique electrical challenges that standard AC breakers cannot safely handle. This automatic electrical current cutoff switch is designed specifically to protect against electrical faults in DC circuits, particularly in solar power systems connected to solar panels, and complies with CE safety standards ensuring its safety and reliability during operation.
The Suntree 32A 2P double pole breaker safeguards both the positive and negative lines simultaneously — delivering complete circuit isolation and maximum protection for your solar investment.
Key Features of the Suntree 32A Double Pole DC Breaker
Dual Pole Protection
The dual-pole design ensures enhanced safety by isolating both the positive and negative lines in the circuit, making it ideal for medium-capacity solar photovoltaic systems, battery storage solutions, and other DC applications.
Non-Polarity Sensitive Design
The SL7-63 is not polarity sensitive — positive and negative wires can be inversed without any risk, simplifying installation and reducing wiring errors on site.
Bidirectional Fault Detection
Since a fault current can flow in the reverse direction to the operating current, the SL7-63 can detect and protect against any bidirectional current — a critical safety feature for solar battery systems where current can flow in both directions.
DIN Rail Mountable
Designed for installation in DIN rail-mounted control cabinets, it is equipped with a test button for safe operation testing and made from high-quality, fire-resistant materials assembled with precision to ensure durability.
Inter-Pole Barrier for Enhanced Isolation
Delivered with three inter-pole barriers to provide increased isolation distance between two adjacent connectors  ensuring safe, clean installation in compact distribution boards.
