Overcurrent circuit breaker Icn=6000A 3P C 25A QuickConnect MCS325

Three-pole circuit breaker with C characteristic is a reliable protection for electrical installations, designed for both professional and home use. Model MCS325 with a rated current of 25A and a short-circuit breaking capacity of 6kA provides effective protection against overloads and short circuits in circuits with a voltage of up to 400V.

Product features and application

This circuit breaker is part of the QuickConnect series, which means that installation is exceptionally quick and easy thanks to the tool-less connection system. This saves time for installers and makes it easier to replace or upgrade the installation. The use of characteristic C makes the circuit breaker cope well with impulse loads, such as motors or transformers – it allows for short-term exceeding of the rated current without unnecessary tripping. Therefore, it is ideal for protecting lighting circuits, socket circuits and electrical appliances requiring higher starting current.

Advantages and benefits

• Quick installation: The QuickConnect system eliminates the need to screw wires, which significantly speeds up installation and reduces the risk of errors.
• High reliability: The rated short-circuit breaking capacity of 6kA (at 230V AC) and 10kA (at 400V) guarantees effective protection of the installation in the event of a failure.
• Versatility: Suitable for protecting various types of circuits – lighting, socket, electrical appliances.
• Safety: Energy limitation class 3 and surge category III provide a high level of protection against the effects of overvoltage.
• Compact dimensions: A width of only 3 modules allows for efficient use of space in the distribution board (83.4 x 52.5 x 70 mm).
• Wide operating temperature range: The ability to operate at temperatures from -25°C to +70°C ensures reliability in various environmental conditions.
• Wire cross-sections: Support for solid wires with a cross-section of 1-35 mm² and stranded wires 1-25 mm² provides great flexibility in choosing wires.

Construction and installation

The circuit breaker is designed for flush mounting, which provides an aesthetic look of the installation. It has a protection degree of IP20, which means protection against touching with fingers and solid objects larger than 12.5 mm. The rear BiConnect terminal with screw connection provides additional safety of the wire connection, and the front BiConnect terminal with QuickConnect system allows for quick and easy connection to the phase busbar. Additionally, the QuickSnap latch facilitates the removal of the circuit breaker without the need to disconnect other installation elements. A transparent flap on the labeling fields protects the markings from damage.
