Description

This RCBO (Residual Current Circuit Breaker with Overcurrent Protection) is designed for industrial and commercial applications, providing reliable protection by combining the functions of a circuit breaker and a residual current device in one compact unit. With a rated current of 20 A, it ensures efficient operation within your electrical systems.

The RCBO is engineered to handle a rated voltage of 415 V and features a robust breaking capacity of 10 kA, making it suitable for demanding environments where safety and reliability are paramount. It also boasts an impressive rated impulse withstand voltage of 4 kV and insulation voltage of 500 V, ensuring durability against transient overvoltages.

Featuring four poles, this device offers comprehensive coverage for three-phase systems. Its power loss is minimized at just 11.8 W, enhancing energy efficiency across operations. The RCBO's electrical durability allows for up to 10,000 cycles, underscoring its long-lasting performance even under frequent use.

Conforming to standards IEC 61009-1/2-1 and EN 61009-1/2-1, this product meets rigorous international quality benchmarks. The degree of protection is IP2X, safeguarding against accidental contact with live parts while maintaining operational integrity.

With dimensions measuring 71 mm in width, 85 mm in height, and a depth of 69 mm—combined with a weight of only 480 g—the RCBO offers ease of installation without compromising on space or functionality. Its operating temperature range from -25°C to +55°C ensures adaptability across varied climatic conditions.

The short circuit capacity stands at an effective rate of 6 kA with the ability to handle cable cross-sections ranging from solid core to multi-wired configurations up to specified limits. This flexibility makes it adaptable for diverse wiring requirements.

Rated frequency options between 50/60 Hz cater to different regional grid specifications while the C curve type provides instantaneous tripping characteristics ideal for general-purpose applications including inductive loads like motors or transformers.

For enhanced safety measures, the residual current type is Type A which detects both AC and pulsating DC components up to a sensitivity threshold set at an industry-standard level—30 mA—providing critical protection against earth faults that could lead otherwise unnoticed hazards within installations.

Additional connectivity options include busbar connections capable up through rigid/flexible configurations allowing seamless integration into existing setups regardless complexity level involved therein; all backed by overvoltage category III classification ensuring resilience amidst challenging scenarios encountered during everyday usage periods alike!

Incorporating arbitrary power supply connection along undelayed earthing switch types further enhances versatility when deploying this vital component part any modern-day electrical infrastructure setup!
