Residual current circuit breaker 3P+N 40A 100mA 10kA Type A CEA640J

Safety and reliability in your installation

A 3P+N residual current circuit breaker (RCCB) is a key element in protecting electrical installations, providing protection against electric shock and fire. This model, with a rated current of 40A and a sensitivity of 100mA, effectively detects earth leakage currents, disconnecting the circuit in the event of a fault. Its short-circuit withstand capacity of 10kA guarantees reliable operation even in difficult conditions.

Installation and application

The circuit breaker is designed for mounting on a DIN rail, making it easy to install and replace. A width of 4 modules allows for efficient use of space in the distribution board. Suitable for use in circuits with a voltage of 400V and a frequency of 50/60Hz, it will work in both domestic and industrial installations. It accepts solid core wires up to 25 mm² and stranded wires up to 16 mm², providing flexibility in wire selection.

Construction features and benefits

• High selectivity: Lack of short-time tripping function and lack of selective protection allows for coordinated operation with other protection devices in the installation.
• Locking: Integrated locking prevents accidental switching on of the circuit breaker after it has been switched off by the residual current device – this increases safety during maintenance work.
• Wide temperature range: The ability to operate at an ambient temperature from -25°C to 70°C ensures reliability even in extreme conditions.
• Compliance with standards: Meets the required safety standards, confirming its high quality and reliability. IP20 protection rating provides protection against finger contact.
• Additional equipment: The ability to expand with additional accessories allows you to adapt the circuit breaker to specific installation needs.
• Characteristic A: Type A sensitivity means that the circuit breaker reacts to both DC and AC currents – ideal for protecting circuits powering electronic devices.
• Impulse withstand: Withstands an impulse withstand voltage of 3kA, which increases its durability and resistance to damage.
