Overcurrent circuit breaker, 6kA, characteristic C, 3-pole, 63A MCN363E

Reliable protection of electrical installations – 3-pole circuit breaker 63A

This 3-pole circuit breaker with a rated current of 63A and characteristic C is a key element of every safe and reliable electrical installation. It provides effective protection against overloads and short circuits, protecting both devices and users. It is ideal for use in both domestic and industrial installations.

This circuit breaker is distinguished by its high quality and compliance with applicable safety standards. Its compact size (3 module width) makes it easy to install in standard distribution boards. The terminal block design allows connection of wires with a cross-section from 1 to 35 mm², providing flexibility in choosing the appropriate cables.

Functionality and safety in one

Characteristic C means that the circuit breaker reacts more slowly to short-term current surges, which is particularly important when connecting devices with motors or other elements generating high starting currents. The rated short-circuit breaking capacity Icn is 6 kA at 400V, which guarantees effective disconnection of the circuit in the event of a failure. Additionally, the high short-circuit strength Icu at 10 kA at 400V provides an additional margin of safety.

• Wide operating temperature range: from -25°C to 70°C – enables operation in difficult environmental conditions.
• Screw terminals (biconnect): provide a secure and durable connection of wires. Possibility to connect both solid wires (up to 35 mm²) and stranded wires (up to 25 mm²).
• Protection degree IP20: protects against accidental contact, ensuring safe use.
• Compliance with standards: IEC 60898-1 and PN-EN 60947-2 – confirms compliance with stringent safety and reliability requirements.
• Energy limitation class: 3 - provides adequate protection in the event of an electric arc.

Installation and application

The circuit breaker is designed for mounting on a DIN rail, which facilitates its installation and replacement. Thanks to its compact size, it fits perfectly into standard electrical distribution boards. It is an indispensable element in every electrical circuit requiring protection against overloads and short circuits – from lighting, through electrical sockets, to more demanding industrial equipment.
