Residual current circuit breaker type A 4-pole FRCmM-40/4/003-A 170333

Safety and reliability in your electrical installation

This four-pole Type A residual current circuit breaker (RCCB) with a rated current of 40A and a tripping current of 0.03A is a key element ensuring the protection of people and equipment against electric shock and the effects of short circuits and overloads. Manufactured by the renowned company Eaton, model FRCmM-40/4/003-A combines advanced technology and a solid construction, guaranteeing long-lasting and trouble-free operation.

Functionality and application

This circuit breaker is designed to protect electrical circuits in residential, commercial and industrial buildings. Its main task is to quickly detect and disconnect circuits in the event of leakage currents to earth, minimizing the risk of user injury. The use of Type A means that it effectively reacts to sinusoidal alternating currents and pulsating DC currents – an ideal choice for modern installations powering electronic devices. Mounting is done on a standard DIN rail, which simplifies integration with existing distribution boards.

Key features and benefits

• High short-circuit strength (10 kA): Ensures reliable operation even in the event of high overvoltages caused by a short circuit. This translates to greater installation safety and reduced repair costs.
• Locking mechanism: The locking mechanism prevents accidental disconnection of the circuit breaker, increasing work safety and preventing unauthorized access.
• Wide range of connectable conductors (1.5 - 35 mm²): Allows connection of conductors of different thicknesses, providing flexibility during installation and allowing adaptation to specific needs.
• Rated impulse withstand voltage (4 kV): The circuit breaker is resistant to sudden voltage surges, ensuring its stable operation in difficult conditions.
• Width of 4 modules: Compact dimensions allow for efficient use of space in the distribution board.
• Ambient temperature in operating conditions (-25 ... 40 °C): The ability to operate within a wide temperature range makes it suitable for applications both indoors and in outdoor environments (with appropriate housing).
• Degree of protection IP20: Protection against finger contact provides additional safety.
• Possibility of additional equipment: Allows expanding the functionality of the circuit breaker by adding accessories, such as status indicators or remote triggers.

Remember – correct selection and installation of a residual current circuit breaker is the basis of a safe and reliable electrical installation!
