Overcurrent circuit breaker, 6kA, C characteristic, 3-pole, 6A MCN306E

Electrical installation protection with Hager MCN306E circuit breaker

The Hager MCN306E circuit breaker is a reliable protection for electrical installations against overloads and short circuits. Designed for use in AC circuits, it offers effective protection for both installers and end-users. The rated short-circuit breaking capacity of 6kA guarantees safety in the event of a failure.

This three-pole circuit breaker with a rated current of 6A and C characteristic is ideal for protecting circuits with a mixed load character – both resistive and inductive. The C characteristic allows it to react more slowly to short current surges, so it tolerates the starting of devices with a motor well. This ensures stable operation of the installation without unnecessary tripping.

Construction and mounting

The MCN306E circuit breaker has been designed with easy installation and convenience in mind. A width of 3 modules allows for efficient use of space in the distribution board. The possibility of flush mounting increases the flexibility of the installation. Screw terminals allow connection of wires with a cross-section from 1 to 35 mm² (solid) or from 1 to 25 mm² (stranded). This makes the circuit breaker compatible with various types of wires used in electrical installations.

Compliance with standards and safety

The circuit breaker meets the requirements of IEC 60898-1 and IEC 60947-2 standards, confirming its high quality and safety of use. It has a rated insulation voltage Ui of 500V and a rated impulse withstand voltage Uimp of 4kV. The energy limitation class is 3, and the surge category is III, providing protection against the effects of overvoltages in the installation. The IP20 degree of protection protects against accidental contact.

Additional features:

• Wide operating temperature range: from -25°C to 70°C, allowing the circuit breaker to be used in various environmental conditions.
• Expandability: Compatibility with additional equipment (e.g. auxiliary contacts) allows you to adapt the functionality of the circuit breaker to individual needs.
• High quality workmanship: Ensures long-lasting and reliable operation of the device.
• Rated short-circuit breaking capacity Icu: 10 kA at 400V (according to IEC 60947-2), providing additional safety in the event of short circuits with high current intensity.
• Vertical comb busbars: Innovative solution facilitating connections between devices in the distribution board, increasing the speed and safety of installation (function available in Hager comb busbars).
