Suntree DC Breaker 20A 2P Double Pole
The Suntree DC Breaker 20A 2P Double Pole is a compact, high-performance direct current miniature circuit breaker engineered specifically for solar photovoltaic systems, battery storage solutions, and off-grid DC power applications. Designed as a robust and reliable 2-pole miniature circuit breaker specifically for direct current applications up to 550V it delivers dependable overload and short-circuit protection for small to medium-capacity DC installations. DIN rail mountable, CE-certified, and built for the demands of solar installers and electricians across Kenya.
Why Choose the Suntree DC Breaker 20A 2P?
Standard AC circuit breakers cannot safely interrupt direct current faults — DC systems require purpose-built protection. The Suntree DC MCB is specifically designed to handle the unique characteristics of direct current Chillnetelectrical, making it the correct and safe choice for any solar PV or DC battery application.
The Suntree 2-Pole 20A DC Circuit Breaker is a compact and reliable solution for protecting small to medium direct current electrical systems, with its dual-pole design ensuring enhanced safety by isolating both the positive and negative lines in a circuit. It is the trusted DC protection component for residential solar systems, small battery banks, and off-grid power setups in Kenya.
Key Features of the Suntree 20A Double Pole DC Breaker
Double Pole Simultaneous Switching
Double pole switching interrupts both DC lines simultaneously for complete isolation, reducing the risk of electrical fires and equipment failure in DC systems. This ensures safe maintenance and full circuit disconnection with a single switch action.
Reliable Overcurrent Protection
Reliable DC overcurrent protection safeguards DC circuits and connected equipment from damage caused by overloads and short circuits. The 20A rating makes it ideal for protecting small to medium solar string lines and battery connections.
Padlockable Toggle
The toggle is padlockable in both the ON and OFF position suntree — allowing secure isolation during system maintenance and preventing accidental re-energisation on site.
DIN Rail Mountable
The DIN rail mounting mechanism simplifies installation in electrical enclosures with a compact design that saves space within electrical panels. Compatible with standard 35mm DIN rails used in solar combiner boxes and distribution boards.
IEC60947-2 Certified
Certified to IEC60947-2 standard for industrial applications in polluted, humid, harsh, and outdoor environments— ensuring it performs reliably across the demanding conditions of Kenyan solar installations.
Wide Operating Temperature Range
Ambient air temperature should be within -5 to +40°C— covering the full range of temperatures encountered in Kenyan residential, commercial, and industrial solar installations.

Where to Use the Suntree DC Breaker 20A 2P
Residential Solar PV Systems
Ideal for protecting DC circuits between solar panels and charge controllers or inverters in residential rooftop solar installations. The 20A rating suits small to medium home solar systems perfectly.
Battery Storage Systems
Safely isolate battery banks in off-grid and hybrid solar systems. The double pole design disconnects both positive and negative conductors simultaneously — essential for safe battery maintenance and system isolation.
Off-Grid Solar Cabins and Rural Electrification
Common applications include connecting solar panel strings to combiners, isolating battery banks from inverters, and protecting DC loads in marine, telecom, and off-grid cabins.
Solar Combiner Boxes
The compact DIN rail design fits neatly inside solar combiner and distribution boxes, providing individual string-level protection for each solar panel circuit.
Wind and Solar Hybrid Systems
Reliable overcurrent protection for wind and solar hybrid DC systems, where variable current conditions demand a robust and responsive circuit breaker.
