Overcurrent circuit breaker, 6kA, characteristic C, 3-pole, 10A MCN310E

Overcurrent circuit breaker – reliable protection for electrical installations

This three-pole overcurrent circuit breaker from Hager, with a rated current of 10A and C characteristic, is a key element ensuring safety in every electrical installation. The rated short-circuit breaking capacity of 6kA guarantees effective protection against the effects of overloads and short circuits. The design adapted for flush mounting, combined with compact dimensions (3 modules wide), allows for discreet integration with existing infrastructure.

Functionality and application

The MCN310E circuit breaker is designed for a wide range of applications – from protecting lighting circuits, through sockets, to electrical appliances requiring protection against overloads. The C characteristic provides a delayed tripping response to short-term current surges, which is particularly important when servicing devices with motors or other elements generating inrush currents during start-up. This minimizes the risk of unnecessary circuit tripping.

Key features and benefits

• High short-circuit breaking capacity (6kA): ensures effective protection of the installation in the event of a short circuit.
• C characteristic: ideal for protecting circuits with devices generating inrush currents, such as motors or transformers. Allows you to avoid unnecessary disconnections.
• Flush mounting: enables aesthetic and discreet integration with the surroundings.
• 3 module width: saves space in the distribution board.
• Touch protection (IP20): increases safety, especially in places accessible to unauthorized persons.
• Wide range of wire cross-sections: possibility of connecting solid wires with a cross-section of 1-35 mm² and stranded wires 1-25 mm², which provides flexibility during installation.
• Operating temperature range -25…70°C: enables operation in difficult environmental conditions.
• Compliance with standards: the product meets strict safety standards, which guarantees its reliability and durability.

Construction and technical parameters

The circuit breaker is made of high-quality materials, which ensures its long-term and trouble-free operation. It has a degree of protection IP20, protecting against touching with fingers and solid bodies larger than 12.5 mm. The rated insulation voltage is 500V, and the rated impulse withstand voltage is 4kV – these parameters guarantee safe operation even in installations exposed to overvoltages. The circuit breaker is adapted to work in AC networks with a frequency of 50-60 Hz. The energy limitation class is 3, and the surge voltage category is III – which indicates a high level of protection against the effects of transient and impulse overvoltages.
