Overcurrent circuit breaker Icn=6000A 3P C 40A QuickConnect MCS340

Three-pole overcurrent circuit breaker with a rated current of 40A and characteristic C is a reliable protection for electrical installations. Designed to protect against overloads and short circuits, it meets safety standards and provides effective protection for both installers and end-users. The rated short-circuit breaking capacity (Icn) is 6kA at 400V, and even 10kA under IEC 60947-2 conditions, guaranteeing safety in the event of a failure.

Features and application

This circuit breaker is ideal for use in electrical installations in residential, commercial and industrial buildings. Thanks to its compact dimensions (83.4 x 52.5 x 70 mm) and width of 3 modules, it is easy to mount in a distribution board. Characteristic C provides delayed tripping for short-term overloads, which is particularly important for devices with motors or other elements generating high starting current – this avoids unnecessary tripping of the circuit. Made of high-quality materials, it ensures long-lasting and trouble-free operation.

QuickConnect technology – saving time and ensuring safety

The MCS340 circuit breaker utilizes QuickConnect technology, which significantly speeds up installation and removal. The plug-in system eliminates the need to screw wires, which translates into time savings and minimizes the risk of errors during installation. In addition, spring clamps ensure constant contact with the wire, increasing safety and connection reliability. The BiConnect system allows connection of wires both with screws and using QuickConnect technology – giving flexibility in choosing the installation method. A transparent flap on the labeling fields protects the markings from damage.

• Fast installation: QuickConnect technology reduces installation time by up to 50%.
• Secure connections: Spring clamps ensure a firm contact with the wire.
• Flexibility: Possibility to connect wires with screws or using the QuickConnect system.
• Durable construction: Made of high-quality materials resistant to mechanical damage and weather conditions (operating temperature: -25°C to +70°C).
• Compliance with standards: Meets the requirements of PN-EN 60898-1 and IEC 60947-2 standards.
• Versatile application: Ideal for protecting lighting circuits, socket circuits and electrical devices with various power consumption.
• Easy identification: Transparent flap on the labeling fields facilitates circuit marking.

Using this circuit breaker is not only protection against failures – it is also comfort of use and confidence in the reliable operation of the electrical installation for many years.
