Overcurrent circuit breaker Icn=6000A 1P C 40A QuickConnect MCS140

Overcurrent switch for safe and efficient installation

This single-pole overcurrent switch with C characteristic, rated current of 40A and short-circuit breaking capacity up to 6kA, is a reliable protection for your electrical installation. Designed for both professional installers and end-users, it combines safety, ease of installation and durability.

Design and functionality

The MCS140 switch from Hager Polo is part of the QuickConnect series, which means significant faster installation thanks to the connection system without the need for screws. This solution saves time and minimizes the risk of errors when connecting wires. BiConnect terminals – both front (QuickConnect system) and rear (screw) – provide flexibility and connection security. In addition, a transparent flap on the description fields protects the markings from damage.

This switch is designed to operate in circuits with AC 230-400V voltage and 50-60Hz frequency. Characteristic C provides delayed tripping with short-term overloads, which is especially important for devices with motors or other elements generating high starting current. Energy limitation class 3 and overvoltage category III guarantee adequate protection in various operating conditions.

Advantages for the installer and user

• Fast installation: The QuickConnect system reduces installation time by up to several dozen percent.
• Connection safety: Constant spring tension on the wire ensures a secure and durable connection, minimizing the risk of loosening the connection.
• Versatility: Possibility to connect solid wires (1-35mm²) and stranded wires (1-25mm²).
• Compact dimensions: 1 module width allows for efficient use of space in the switchgear (83.4 x 17.5 x 70 mm).
• Durability: Made of high-quality materials, resistant to environmental conditions (operating temperature -25°C to +70°C).
• Easy identification: Transparent flap on the description fields makes it easy to mark the circuit.
• Compliance with standards: Meets the requirements of PN-EN 60898-1 and IEC 60947-2 standards, ensuring safety of use.
• Design support: Possibility to use the Hager Ready application for designing switchgear with the QuickConnect system.

This switch is not only a protective element – it is an investment in user comfort and peace of mind resulting from the certainty of the electrical installation. It provides effective protection against overload and short circuit, and its modern design makes it easy to work with both professionals and people who take care of their home themselves.
