Schneider Electric Acti9 iC60H Miniature Circuit Breaker, 2-Pole, 4 A, Type C, 133 V DC, 10 kA Breaking Capacity

Safeguard against power faults with this MCB from Schneider Electric. It stops current overloads and power surges in their tracks thanks to a thermal-magnetic tripping mechanism. As a type-C unit, it trips when it receives five to ten times its 4A rated current, so you can depend on a prompt response. The VisiSafe feature makes it easy to stay informed – just look for the green strip to make sure the contacts are positioned correctly. Thanks to clip-on DIN rail mounting, installation's a breeze. You can padlock the breaker for extra security if needed.

• Handles high loads with a breaking capacity of 10kA at 415V AC

• Commercial lighting systems

This unit fits easily into smaller spaces with its compact dimensions of 36 (W) x 85 (L) x 78.5mm (D).

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.

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.
