TOMZN RCCB 2P 40A 30mA Residual current Circuit breaker

TOMZN RCCB 40A 30mA Residual current Circuit breaker

The TOMZN RCCB 40A 30mA is an electronic device designed to protect against electric shocks and fire caused by earth leakage current. Here are the technical specifications for this RCCB:

• Rated voltage: 230/400V AC – This RCCB is designed to operate within a range of 230/400 volts AC. This makes it suitable for use in a variety of residential, commercial, and industrial applications.
• Rated current: 40A – The RCCB has a rated current of 40 amperes, which means that it can handle up to 40 amperes of current flowing through it without tripping.
• Rated residual operating current: 30mA – This refers to the minimum amount of residual current that the RCCB is designed to trip at. The RCCB will detect any imbalance of current between the live and neutral wires, and if the residual current exceeds 30 milliamperes, it will trip and cut off the power supply.
• Rated residual non-operating current: 15mA – This is the maximum amount of residual current that the RCCB can withstand without tripping. It ensures that the RCCB will not trip unnecessarily, such as during transient voltage spikes or momentary power surges.
• Tripping time: ≤ 0.1s – This is the time taken by the RCCB to trip and disconnect the power supply when it detects an earth leakage current. A fast tripping time ensures quick protection against electric shock and fire.
• Short circuit capacity: 10kA – This refers to the maximum amount of fault current that the RCCB can handle without being damaged. A higher short circuit capacity means that the RCCB can withstand larger fault currents, making it suitable for use in high-current applications.
• Operating temperature range: -25°C to +40°C – The RCCB is designed to operate within a temperature range of -25°C to +40°C. This means that it can operate reliably in a wide range of environmental conditions.
• Mounting: DIN rail – The RCCB can be mounted on a standard DIN rail, which is a common mounting option for electrical equipment.
• Conforms to IEC 61008-1 – This RCCB conforms to the international safety standard IEC 61008-1, which ensures that it has been designed and tested to meet strict safety standards. This ensures that the RCCB is safe to use and can provide reliable protection against electric shock and fire.

The RCCB is a safety device that trips off the power supply when it detects a current imbalance between the live and neutral wires. This imbalance indicates that current is leaking to earth, which can be potentially dangerous. The tripping time of this RCCB is less than 0.1 seconds, which ensures quick protection in case of an electrical fault. The RCCB can handle a short circuit capacity of up to 10kA, which makes it suitable for use in industrial and commercial installations. The device conforms to the international safety standard IEC 61008-1, ensuring reliability and safety.
