DESCRIPTION

ZJBeny 125A 2-Pole DC Circuit Breaker with IP65 Enclosure

Reliable Isolation and Over-Current Protection for DC Power Systems

The ZJBeny BDM series 2-pole DC circuit breaker is engineered to provide robust, high-performance protection in Battery Energy Storage Systems (BESS), solar PV arrays, EV charging infrastructure, and other demanding direct current applications. With a rated operational voltage of 500V DC and a current rating of 125A, this breaker is designed to safely manage and isolate DC circuits in critical environments, reducing the risk of electrical faults and equipment damage.

Unlike generic DC breakers that may struggle with arc extinguishing or lack proper weatherproofing, the ZJBeny unit is housed in a UV-resistant, IP65-rated enclosure, making it suitable for outdoor installation in Australia's harsh conditions. It complies with IEC 60947-2 and AS60947.2 standards, ensuring trusted performance for professional-grade solar, backup power, and renewable energy systems. The non-polarised design simplifies wiring, while the lockable transparent cover allows for easy visual inspection and tamper resistance.

Key Features

  • High DC interrupting capacity rated at 125A and 500V DC for safe circuit isolation
  • 2-pole (2P) configuration provides simultaneous disconnection of both positive and negative conductors
  • IP65 weather-resistant enclosure with UV-stabilised housing protects against dust, water, and sun exposure
  • Non-polarised terminals allow flexible wiring without polarity concerns, reducing installation errors
  • 10,000 mechanical and 2,000 electrical cycles ensure long service life in frequent switching applications
  • SAA and TUV certified to meet Australian and international safety standards
  • Lockable transparent hinged cover enables visual status checks while preventing unauthorised access
  • Pre-moulded cable entry knockouts in the enclosure base for versatile conduit or gland installation

Built for Demanding Environments

The ZJBeny DC circuit breaker is purpose-built to withstand the rigours of Australian outdoor and industrial settings. The IP65-rated enclosure ensures complete protection against dust ingress and low-pressure water jets, making it ideal for solar farms, marine installations, caravan and RV setups, and remote off-grid systems. The UV-stabilised plastic resists degradation from prolonged sun exposure, maintaining structural integrity and electrical safety over time.

Inside the enclosure, the moulded case circuit breaker (MCCB) features a robust toggle switch with clear ON/OFF indication and an integrated push-to-trip button for manual testing. This allows operators to verify the trip mechanism without exposing live components, enhancing routine maintenance safety. The breaker's DC-21B utilisation category confirms its suitability for resistive loads typical in battery charging and solar combiner boxes.

Applications

This DC circuit breaker is a versatile solution for a wide range of low-voltage DC applications, including:

  • Solar PV array isolation and combiner box protection
  • Battery energy storage system (BESS) disconnect switches
  • EV charging station DC supply protection
  • Uninterruptible power supply (UPS) battery banks
  • Caravan, RV, and marine auxiliary power circuits
  • Industrial DC motor and control panel isolation
  • Off-grid and tiny home renewable energy systems

Why Choose the ZJBeny BDM Series?

Selecting a high-quality DC circuit breaker is critical for system safety and longevity. The ZJBeny BDM series addresses common failure points found in inferior products, such as contact welding under high DC loads, inadequate arc quenching, and enclosure degradation in outdoor settings. By using a 2-pole design, it ensures complete isolation of the circuit, which is essential for ungrounded battery systems commonly found in mobile and off-grid installations. The no-polarity feature further reduces the chance of miswiring, a frequent cause of breaker malfunction.

With SAA and TUV certifications, this breaker meets stringent Australian and international safety requirements, providing peace of mind for installers and system owners. The 5-year warranty underscores ZJBeny's confidence in the product's durability and performance.

Secure your DC power system with the ZJBeny 125A 2-pole circuit breaker today — engineered for reliable protection in solar, marine, and industrial applications across Australia.
