A9F54363, Schneider Electric Acti 9 iC60H MCB, 3P, 63A Curve C, 440V AC, 100 → 133V DC, 10 kA Breaking Capacity

Schneider Electric Acti9 iC60H MCB Range

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.

Benefits & Features

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

What does a miniature circuit breaker do?

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.

What are the differences in the Tripping Curves B, C, and D?

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

Schneider Electric MCB, Screw Terminals, 63A Current Rating - iC60H series - A9F54363

Are you working with inductive loads where switching surges are high? Install this MCB from Schneider Electric to be sure your downstream equipment is safe, even in the event of an overcurrent or short circuit. You'll be protected from the risk of electric shocks, too. The VisiSafe feature makes visual monitoring a breeze even in challenging conditions, with a green strip to indicate contacts are in the safe position and a red window showing when the MCB has tripped due to a fault.

Features & Benefits

• Type-C tripping characteristics mean it trips at 5 to 10 times the 63A rated current, making it suitable for protecting high inductive loads and fluorescent lighting
• Screw terminals with twice the standard tightening torque help you make quick and secure connections
• Double clip allows the breaker to be conveniently dismounted while the comb busbar stays in place

Applications

• Factory machinery
• Commercial premises
• Residential buildings

What's the difference between an MCB and a fuse?

The main difference between an MCB and a fuse is that while a blown fuse must be replaced, an MCB can simply be reset once the fault has been identified and fixed. An MCB can also be used to isolate part of a circuit for inspection or repair.
