A9F55225, Schneider Electric Acti 9 iC60H MCB, 2P, 25A Curve D, 440V AC, 100 → 133V DC, 10 kA Breaking Capacity

Schneider Electric Acti9 iC60H MCBs - 2 Pole

iC60H 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 downtime

Q: What exactly 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.

Q: What is 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 Terminal Contacts, 85mm Length - iC60H Series - A9F55225

Stop the flow of dangerous currents in the nick of time with this MCB from Schneider Electric. It provides protection for your machinery against short circuits and overloads, helping to prevent damage and downtime. The unit's operational status is easy to read at a glance thanks to the red/green VisiTrip indicator window at the front. As this strip indicates when the unit's contacts are open, users carrying out routine maintenance can rest assured the power is safely isolated while they work.

• DIN-rail mounting for easy installation
• Type-D unit trips at between 10 and 14 times the 25A rated current to protect heavy-duty equipment
• IP20 rating indicates it's touch-proof and protected against dust and solid objects over 12mm
• Rocker actuator for easy resets

Applications

• Agricultural machinery
• Industrial automation
• Mechanical engineering

How big is this breaker?

It has compact dimensions of 36 (W) x 85 (L) x 78.5mm (D), so is suitable for use when space is at a premium.

What's the breaking capacity of this MCB?

It has a breaking capacity of 10kA. This means that even after a substantial surge, it will continue to function normally following a reset.
