Overcurrent switch Icn=6000A 1P B 40A QuickConnect MBS140

Overcurrent switch for modern installations

This single-pole overcurrent switch with B characteristic, rated current of 40A and short-circuit breaking capacity up to 6kA (at 230V AC), is a reliable protection for your electrical installation. Designed for speed and convenience of installation, it is ideal for both new and modernized facilities. Its compact dimensions (83.40 x 17.50 x 70 mm) allow for efficient use of space in the distribution board.

QuickConnect technology – saving time and ensuring safety

The switch is equipped with a QuickConnect system that revolutionizes the way wires are connected. Instead of traditional screwing, simply snap in the wire – this reduces installation time and minimizes the risk of errors. Additionally, a spring constantly presses the wire against the clamp, ensuring a secure connection and increased protection against touch. The BiConnect system offers both screw terminals (rear) and QuickConnect plug-in terminals (front), providing flexibility in choosing the connection method. A transparent flap protects the labeling fields from damage.

Functionality and compliance with standards

The switch meets the requirements of PN-EN 60898-1 and IEC 60947-2 standards, providing effective protection against overload and short circuit. Energy limitation class 3 and surge category III guarantee its reliability in various operating conditions. A width of 1 module makes it easy to install in standard distribution boards. The possibility of flush mounting increases its versatility. Suitable for operation at temperatures from -25°C to 70°C. The rated impulse withstand voltage Uimp is as high as 4kV. The cross-section of the connectable single-wire conductor is 1-35mm², and the multi-wire conductor is 1-25mm².
