Electric Acti Schneider 9 Acti9 iDT40T MCB, 3P, 20A Curve C, 400V AC, 6 kA Breaking Capacity – A9P22720

Schneider Electric Acti 9 DT40 MCB 1 PoleActi 9 DT40 series multi-standard circuit breakers combine circuit protection against short circuit currents and circuit protection against overload currents it also protects people against indirect contact with TN and IT neutral systems. Fully compliant with standards IEC/EN 60898 and IEC/EN 60947-2. ACTi 9 is fully tested, approved and certified by national and international third parties. It guarantees that your installation is safe and compliant with all relevant safety standards which demonstrates to your customers that you use industry-approved materials and best practices. These MCBs are normally used for high inductive loads where switching surges are high. Providing essential protection in industrial and commercial buildings, these miniature circuit breakers work especially well in polluted environments and networks.VisiSafe guarantees the downstream circuit is always safe regardless of overvoltage conditions, even in the most demanding environments; the green strip indicates the safe position of contacts.VisiTrip red window on the front face indicates fault tripping allowing fast diagnosis, resolution, and reclosing loads for easier building management and reduced downtimeBenefits and FeaturesDownstream circuit is always safeClass-2
insulation: ensures continuous protection for both operators and unqualified persons. Insulated terminals (IP20) Highly durable with robust connections that provide twice the standard tightening torque. Provide greater continuity of service thanks to VisiTrip.
