Hager CDA684C RCCB 3P+N 100A 30mA Type A HI

The Hager CDA684C is a high-quality residual current circuit breaker (RCCB) designed for reliable protection against earth faults. With 3P+N poles, a rated current of 100A, and a sensitivity of 30mA, it is suitable for main distribution boards in residential and commercial buildings. The Type A characteristic ensures detection of pulsating DC residual currents, while the HI (high immunity) version minimizes nuisance tripping caused by transient surges or lightning strikes.

• 3P+N poles for three-phase systems with neutral
• Rated current 100A – ideal for high-load applications
• 30mA sensitivity for personal protection
• Type A – detects sinusoidal AC and pulsating DC residual currents
• HI (High Immunity) – resists unwanted tripping from voltage spikes
• Instantaneous tripping for rapid disconnection

Install this RCCB on a standard 35mm DIN rail to enhance electrical safety. Suitable for use in TT, TN, and IT systems. Always follow local wiring regulations.
