High-Performance 600V Double Pole DC Circuit Breaker for Solar PV Systems

Safeguard your photovoltaic and battery storage infrastructure with this robust double pole DC breaker, engineered specifically for the demands of direct current environments. Designed for caravan, marine, industrial and off-grid PV systems. These circuit breakers provide essential protection against overcurrents and short circuits, this miniature circuit breaker (MCB) ensures that your off-grid, marine, or caravan electrical systems operate with maximum safety and reliability. Featuring a 40A capacity, it is perfectly sized to protect specific DC load requirements while maintaining stable power flow.

Advanced Arc Fault and Overcurrent Protection

Direct current circuits present unique challenges compared to standard alternating current, particularly when it comes to extinguishing electrical arcs during a fault. Utilizing sophisticated thermo-magnetic trip technology, this DC circuit breaker is explicitly designed to detect and safely interrupt harmful DC arcs up to 600V. By swiftly disconnecting the circuit during an overload or short circuit, it significantly mitigates the risk of cable damage, electrical fires, and catastrophic equipment failure. This makes it an indispensable safety device for 12V, 24V, and 48V battery systems, as well as high-voltage solar arrays.

Non-Polarised Design for Safer, Simpler Installation

A major advantage of this specific solar MCB is its non-polarised architecture. Traditional polarised breakers require strict adherence to current flow direction, which can lead to dangerous failures if wired incorrectly or if reverse currents occur during complex battery charging cycles. The non-polarised nature of this breaker eliminates the risk of directional wiring errors, allowing safe bidirectional current flow. This simplifies the installation process for both professional auto-electricians and off-grid enthusiasts while drastically reducing potential safety hazards.

Key Features

  • 40A rated capacity to suit your specific array or battery load specifications
  • Non-polarised internal design safely handles bidirectional current without risking internal damage
  • 6kA short-circuit breaking capacity (Ics/Icu) ensures reliable interruption of severe electrical faults
  • 6kV impulse withstand voltage (Uimp) provides exceptional resilience against system surges
  • Standard DIN rail compatibility allows for rapid, secure mounting in standard electrical enclosures
  • Clear visual status indicators confirm isolation state at a glance for safe maintenance

Built Tough for Demanding Environments

Constructed with high-quality, flame-retardant thermoplastic, this 2 pole DC circuit breaker is designed to meet strict IEC/EN 60947-2 standards. It features a Pollution Degree 3 rating, meaning it is built to withstand the ingress of dust and moisture commonly experienced in demanding Australian applications, including remote off-grid sheds, camper trailers, and marine engine bays. The secure tunnel terminals ensure excellent cable retention, minimizing resistance and preventing the development of dangerous hot spots over the lifespan of your installation.

Ensure the longevity and safety of your renewable energy architecture by integrating this highly reliable Exotronic 40A 2-Pole DC Circuit Breaker (MCB) into your distribution board today.

Solved Specific Need
Size: 10 Ft (Type B with Clamp), Color: White
Nice product which solved a problem of needing USB power clamped to a very thick work table. Most power strips with a clamp do not accommodate thick tables between 1.75" and 2" so I was happy to find this one. Successfully provides power to all my USB devices even a laptop (although charging is a bit slower compared to the OEM power adapter).

One minor bug
Size: 10 Ft (Type B with Clamp), Color: Black
I received this today and mounted it to the table I have next to my recliner. I plugged it into a remote control outlet so I can turn everything off at once. I used two of the AC outlets for the power recliner. I then plugged a USB powered fan into one of the USB-A ports. I plugged the power cable from a set of speakers positioned next to the headrest of the recliner into the other USB-A port. I used one of the USB C outlets to charge my tablet. When I hit the switch on the remote control to turn off power to the strip before going to bed I discovered a bug. The only way I can describe it is a cross port power bleed. After killing power to the strip my speakers were still playing, not well as they had static. I discovered by trial and error that if I unplugged my tablet the problem stopped. Apparently if you have something with a battery plugged into one of the USB ports and have something plugged into the other USB ports it pulls power from the device with the battery to try and power the other devices plugged in. Other than this one problem it seems to be just what I was looking for.

Mounts to desktop
Size: 10 Ft (Type B with Clamp), Color: Black
Helps keep the desktop clutter down. Sometimes I need to charge flashlights, earphones, hearing aids, portable battery chargers and the like. I don’t want to plug these onto my computer so this unit fits that need. Sturdy desk mount so one hand plugging in and unplugging usually works fine.

Decent, gets warm though
Size: 10 Ft (Type B with Clamp), Color: Black
Compact with a nice long power cord. However, it does get warm, which makes me nervous, seeing as it is clamped to a wooden table...
