Acti9: Modular Residual Current Circuit Breaker (RCCB) with Reclosing Device
Introducing the Acti9, a REDs modular residual current circuit breaker (RCCB) with recloser. This is a high-quality 2P circuit breaker with a rated current In of 25A and a sensitivity of 30 mA. It is distinguished by its protection class of type A.
Effective and Reliable Protection
The Acti9 modular circuit breaker provides robust protection against electric shock from direct or indirect contact. This product also offers effective protection against fire risks. The Acti9 is capable of disconnecting loaded electrical circuits that are already protected from overloads and short circuits.
Auto Restart and Specific Use
One of the outstanding features of Acti9 is that it automatically restarts after monitoring the insulation of the downstream circuit. It should be noted that the Acti9 RED version is specifically designed for residential applications and is used exclusively on TT and TN-S earthing systems.
Standard Compliant and High Capacity
The Acti9 fully complies with the EN 60557 standard. The product has a rated breaking and short-circuit capacity (Im/IΔm) of 630 A and a conditional short-circuit current (Inc/IΔc) of 6 kA. It boasts a mechanical resistance that can extend up to 4000 cycles.
