Hager ADM470QC interruttore differenziale magnetotermico 4P 6kA C20 30mA tipo A Quick Connect

Electricians and panel builders needing compact, reliable protection for three-phase circuits will appreciate the Hager ADM470QC. This 4-pole RCBO combines overload and residual current protection in one DIN rail module, with Quick Connect terminals for fast, tool-free wiring.

Key specifications

• Rated current: 20 A
• Residual operating current: 30 mA
• Tripping characteristic: C
• Breaking capacity: 6 kA
• Residual current type: A
• Rated voltage: 400 V AC
• Number of poles: 4
• Connection: Quick Connect (QC/QB)
• Neutral conductor protection: Yes
• Standard: DIN EN 61009-1 (VDE 0664-20)

Why choose it

The integrated neutral conductor protection ensures full disconnection in the event of an overload, while the Type A residual current detection handles AC and pulsating DC faults. Its compact 4-module width saves space in distribution boards.

Ideal use cases

• Protection of three-phase circuits in commercial and industrial installations
• Retrofit projects where space is limited
• Applications requiring both overcurrent and earth leakage protection

Good to know

The Quick Connect terminals accept solid or stranded conductors without ferrules, reducing installation time. The device is suitable for 50/60 Hz systems.
