Schneider Electric Resi9 RCCB 4P 40A 30mA tyyppi A R9R22440

The Schneider Electric Resi9 RCCB 4P 40A 30mA Type A is a residual current circuit breaker engineered for reliable protection against earth leakage currents in residential and commercial installations. Its Type A tripping characteristic ensures detection of alternating and pulsating direct residual currents, making it ideal for circuits with modern electronic loads.

Advantages

This RCCB offers robust protection with a rated residual current of 30 mA, providing personal safety against electric shock. The four-pole design supports three-phase systems with neutral, ensuring comprehensive coverage. Its compact 8-module width saves space on the DIN rail, while tunnel terminals accommodate conductors up to 35 mm² for secure connections. The device meets EN/IEC 61008-1 standards, guaranteeing quality and performance.
