HAGER CDA263J RCCB Residual Current Circuit Breaker 1P+N 63A 30mA Type A 6kA 230V 2-Module DIN Rail

The HAGER CDA263J stands out among residual current devices by combining a robust 63 A rated current with a sensitive 30 mA trip threshold in a compact 2-module design, delivering dependable protection against earth leakage faults in demanding residential and light commercial installations. Unlike basic RCCBs that may sacrifice performance for size, this unit maintains a 6 kA breaking capacity and Type A tripping capability, ensuring it handles both sinusoidal AC and pulsating DC residual currents with confidence.

Highlights

• 1P+N configuration with 63 A rated current and 30 mA residual operating current for effective personnel and fire protection.
• Type A residual current detection covers alternating and pulsating direct currents, ideal for circuits with electronic loads.
• 6 kA rated short-circuit breaking capacity provides reliable interruption under fault conditions.
• Compact 2-module width saves space on standard 35 mm DIN rails without compromising performance.
• Wide connection range accepts rigid conductors from 1 to 25 mm² and flexible conductors from 1 to 16 mm².
• Designed for 230 V AC networks at 50/60 Hz, with an operating temperature range of -25 °C to +40 °C.

In daily use

Installation is straightforward thanks to the DIN rail mounting and clearly marked terminals, while the instantaneous tripping characteristic ensures rapid disconnection when a residual current of 30 mA or more is detected. The device's IP20 terminal protection and IP40 rating when installed in an enclosure make it suitable for distribution boards in homes, offices, and small commercial premises. With an electrical endurance of 10,000 cycles and mechanical endurance of 20,000 cycles, the CDA263J is built for long-term reliability, reducing maintenance concerns over its service life.
