Residual current circuit breaker 25A, 30mA, 2-pole, type AC CDC225J

Residual Current Device – Safety and Protection in Your Installation

This two-pole residual current device with a rated current of 25A and a tripping current of 30mA is a key element ensuring safety in every electrical installation. The device is designed to protect people from electric shock and to limit the effects of equipment damage, including the risk of fire. Made in AC type, it effectively reacts to leakage currents, providing a quick disconnection of the circuit in case of a failure. Mounting is done on a DIN rail, which facilitates integration with the existing distribution board.

Features and Application

The CDC225J residual current device from Hager is a reliable solution for both professional installers and end-users. Its compact dimensions (70 mm deep and 35 mm wide – occupies 2 modules) allow for easy installation even in limited space. The device is characterized by high resistance to shock current (0.25 kA) and the ability to withstand short-circuit currents up to 6 kA, which guarantees its reliability in difficult operating conditions. The rated insulation voltage Ui is 500 V, and the rated voltage is 230 V.

• Protection against electric shock: Quick disconnection of the circuit when a leakage current is detected minimizes the risk of electric shock.
• Equipment protection: Protects electrical devices from damage caused by short circuits or overloads.
• DIN rail mounting: Enables easy and quick installation in standard distribution boards.
• Compact dimensions: Occupies only 2 modules, saving space in the distribution board.
• High durability: Ability to withstand short-circuit currents up to 6 kA ensures the reliability of the device.
• AC type: Effectively reacts to sinusoidal alternating leakage currents.

Additional Information and Advantages

The CDC225J circuit breaker has a lock that prevents accidental switching on or off, which increases safety. The cross-section of the connected single-wire conductor can range from 1 to 25 mm², and the multi-wire conductor from 1 to 16 mm², ensuring compatibility with different types of conductors. The device operates in a temperature range from -25°C to 40°C, allowing it to be used in various environmental conditions. The IP20 degree of protection provides protection against finger contact and access to hazardous live parts. The circuit breaker complies with EN 61008-1 standard and has an impulse withstand voltage Uimp of 4 kV.
