Combined residual current circuit breaker RKP – safety and protection of the installation

The RKP 1P+N 10A residual current circuit breaker with C characteristic and 30mA differential current is a reliable device used to protect electrical circuits against the effects of overloads, short circuits and electric shock. It is a key element of every modern electrical installation, both in residential and commercial buildings. The device combines the functions of an overcurrent circuit breaker and a residual current circuit breaker, providing comprehensive protection.

Construction and principle of operation

The RKP 1P+N circuit breaker is characterized by a compact design, allowing for mounting on a DIN rail. Its construction is based on the combination of an overcurrent tripping mechanism (C characteristic) with a ground fault current sensor. Characteristic C means that the circuit breaker reacts with a certain delay to short-term current surges, which is particularly important for inductive loads (e.g. motors, transformers). A differential current of 30mA ensures a quick response in the event of a ground fault, minimizing the risk of electric shock.

Application and benefits

This model of circuit breaker is widely used in protecting lighting circuits, socket outlets and electrical appliances in residential and public buildings. Its versatility makes it ideal for both electrical installers during the implementation of new projects and for end users looking for reliable protection of their installation.

• Comprehensive protection: Protects against overloads, short circuits and electric shock.
• C characteristic: Suitable for inductive loads, minimizes the risk of unnecessary tripping.
• 30mA differential current: Provides a quick response in the event of a ground fault, protecting against electric shock.
• Compact dimensions: Allows for easy mounting in a distribution board.
• DIN rail mounting: Standard mounting simplifies installation and device replacement.
• Compliance with standards: The device meets the required safety standards (IEC 61009-1).

Additional information

The RKP 1P+N circuit breaker with a rated current of 10A is designed to operate in networks with a voltage of 230V AC. It has a short-circuit breaking capacity of up to 4.5kA (depending on the manufacturer), which ensures effective protection in the event of a serious failure. It is important to properly select the rated current of the circuit breaker to the protected circuit – a value that is too low will cause frequent unnecessary tripping, and a value that is too high – may lead to damage to the installation or devices connected to it.
