Schneider Electric Acti 9 iC60H MCB, 1P, 3A Curve B, 100 → 133V AC, 72V DC, 10 kA Breaking Capacity

C60H 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

• 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

IEC 60898 - Relates to Low Voltage Circuit Breakers for use in household and similar
Installations. In the UK traditionally known as miniature circuit breakers
(MCB’s).
IEC 60947-2 Relates to Low Voltage Circuit Breakers for use in industrial and similar
Installations. In the UK traditionally known as moulded case circuit breakers
(MCCB’s) and also air circuit breakers (ACB’s).

A: 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 yourself and your equipment safe from overcurrents with this MCB from Schneider Electric. It trips when it encounters three to five times the rated current of 3A. With its type B tripping characteristics, this breaker is ideal for protecting resistive loads such as lighting or electronic circuits. A 240V AC voltage rating makes it suitable for use with the UK mains supply. As the MCB is mountable on a DIN rail, it helps you to build a tidy system. Compact dimensions of 85 (L) x 18 (W) x 78.5mm (D) take up little space in busy arrangements.

• Single-pole operation is ideal for protecting domestic and low-power commercial devices
• VisiSafe green strip lets you see at a glance whether the contacts are correctly positioned
• Padlockable to prevent tampering

• Data centres
• Commercial buildings
• Educational institutions

Both an MCB and a fuse protect equipment against damage from overcurrents and people from electric shock. The main difference is that a fuse is single-use and always has to be replaced once blown. On the other hand, you can reset a tripped MCB after you've identified and fixed the fault that caused it to cut the electrical flow.
