Schneider Electric Acti 9 iC60H MCB, 3P, 32A Curve D, 440V AC, 100 → 133V DC, 10 kA Breaking Capacity

Introducing Schneider Electrics iC60H series of multi-standard circuit breakers which combine circuit protection against short circuit currents and circuit protection against overload currents alongside protecting users 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 the user's installation is safe and compliant with all relevant safety standards. 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 downtime.

• Downstream circuit is always safe
• Class-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
• Double clip for dismounting with comb busbar in place

It protects wires from overloads and short-circuits. For overload protection the temperature of a bimetal, through which the current passes is decisive. If the nominal current—the current the circuit breaker is designed for—rises slightly, the bimetal heats up to a greater extent and, after a certain period of time, this causes the switching mechanism to trip. Today MCBs are installed in all our homes, offices and other buildings, protecting the electrical wires from damage. They have the advantage that they can be manually reset without having to replace wire as in the case of the traditional fuse. The MCBs have either a button or lever that can be flicked to reset it. They are used instead of fuses due to their convenience and improved safety features.

Curve B: Tripping: 3 to 5 times the rated current.
Applications: protection of generators, persons, very long cables
Curve C: Tripping: 5 to 10 times the rated current
Applications: protection of circuits and general applications
Curve D: Tripping: 10 to 14 times the rated current
Applications: protection of high surge circuits, welders, transformers and motors

Keep your equipment and workers safe with this MCB from Schneider Electric. It has type-D tripping characteristics, meaning it trips at 10 to 14 times its rated current of 32A. This makes it an ideal choice for protecting high inductive loads such as those you'd expect in welders, transformers and motors. As a three-pole device, the breaker is compatible with the three-phase electrical systems that are standard in industrial settings. A rocker reset actuator means you can reset it with a simple flick of a switch.

• VisiSafe feature for easy visual monitoring even in challenging conditions, with a green strip to show contacts are in a safe position and a red pane to indicate a fault
• Class-2 insulation keeps users safe from shocks
• Double clip allows you to dismount the MCB while keeping the comb busbar in place

• Factory machinery
• Metalworking facilities
• Electrical distribution

This MCB has screw terminals with twice the standard tightening torque, helping you make your connections quickly and safely in the knowledge that they won't shake loose.
