Schneider Electric RKN2P Residual Current Circuit Breaker 2P 25A 300mA Type A

The Schneider Electric RKN2P is a high-quality 2-pole residual current circuit breaker (RCCB) engineered to ensure reliable electrical safety in various environments. This device is designed to detect leakage currents and automatically disconnect the circuit, thereby preventing potential electric shocks and protecting electrical installations from damage. With a rated current of 25A and a sensitivity threshold of 300mA, it serves as a critical safety component for modern electrical distribution systems.

Advantages

The primary advantage of this RCCB is its Type A classification, which allows it to detect both standard alternating current (AC) and pulsating direct current (DC) residual currents. This makes it significantly more versatile and safer than standard Type AC devices, especially in modern homes and offices equipped with electronic devices that may produce pulsating DC components. The robust construction by Schneider Electric ensures long-term durability and consistent performance under standard operating conditions.

Suitable for

• Residential electrical distribution boards
• Commercial building power systems
• Protection of circuits with electronic equipment
• General electrical safety in indoor installations

When it may not be suitable

This device is not intended for use in circuits where the load current exceeds 25A, as this would lead to overheating and potential failure of the breaker. Additionally, it is not designed for high-sensitivity applications requiring 10mA or 30mA protection, such as direct protection for bathroom or wet area outlets, where a lower sensitivity threshold is required to prevent injury.

Key specifications

• Number of poles: 2
• Rated current: 25A
• Residual current sensitivity: 300mA
• Type: A (AC and pulsating DC protection)

How to use

The installation of the Schneider Electric RKN2P must be performed by a qualified electrician in accordance with local electrical regulations. The device is typically mounted on a standard DIN rail within a distribution board. Ensure that the supply cables are securely connected to the input terminals and the load cables to the output terminals, following the wiring diagram provided on the device casing. After installation, the device should be tested using the integrated test button to verify its mechanical and electrical functionality.

What to consider before purchase

• Verify that the 25A rating is sufficient for your specific circuit load.
• Ensure the 300mA sensitivity is appropriate for your application, as this is typically used for fire protection rather than direct human contact protection.
• Confirm that your electrical system requires a 2-pole device.

Usage recommendations

Regularly test the residual current circuit breaker using the test button at least every six months to ensure the internal mechanism remains operational and the device can trip correctly in the event of a fault.
