The Hager ADM420QC FI-Leitungsschutzschalter is a four-pole residual-current circuit breaker with overcurrent protection, designed for safe and dependable protection in modern electrical installations. It combines reliable earth-leakage protection with neutral conductor overload protection, making it a solid choice for demanding setups.

Key Features & Design

• 4-pole design (4P) for comprehensive circuit protection.
• Short-circuit rating: 6 kA breaking capacity.
• Nominal current: 20 A (B20A) with integrated residual current protection.
• Residual current rating: 30 mA for sensitive earth-leakage protection.
• Tripping characteristic: Type A (detects AC and pulsating DC residual currents).
• Standard compliance: DIN EN61009-1 (VDE 0664-20) ensuring safety and performance.
• Neutral conductor overcurrent protection adds safety in multi-wire circuits.

Performance & Benefits

This device protects people and electrical equipment by quickly disconnecting on earth faults while guarding circuits against overloads. The 30 mA residual current threshold helps detect even small leakage, and the 6 kA breaking capacity handles fault currents safely. With DIN EN61009-1 compliance, it meets modern safety standards, providing reliability and peace of mind in residential, commercial, and light industrial applications. The dedicated neutral conductor protection further enhances safety in complex wiring scenarios.

Choose the ADM420QC for a trustworthy, high-performance FI-Leitungsschutzschalter that combines robust protection with straightforward integration into standard electrical installations.
