Overcurrent switch Icn=6000A 3P B 10A QuickConnect MBS310

Three-pole circuit breaker with a rated current of 10A and B characteristic, providing reliable protection for electrical installations. Designed for efficient and safe operation, it meets the requirements of both professional installers and end-users. The rated short-circuit breaking capacity (Icn) is 6 kA at 400V, and even 10 kA (Icu) according to IEC 60947-2, guaranteeing effective protection against overloads and short circuits.

Features and application

This circuit breaker from the MBS310 series is designed to protect electrical circuits in residential and commercial buildings. Its compact dimensions (83.4 x 52.5 x 70 mm) and 3-module width allow for easy installation in standard distribution boards. The B characteristic ensures fast tripping in the event of short circuits, while allowing tolerance for short-term overloads, typical of devices with motors. Made of high-quality materials, it ensures long-lasting and trouble-free operation. The rated insulation voltage Ui is 500V, and the rated impulse withstand voltage Uimp is 4kV.

Advantages of the QuickConnect system

The circuit breaker is equipped with an innovative QuickConnect connection system, which significantly speeds up and simplifies installation. Instead of traditional screw connections, simply snap the wires into the terminals – saving time and space. This system also ensures constant spring pressure on the wire, increasing safety and connection reliability. Additionally, the rear BiConnect terminal with screw fixing eliminates the risk of incorrect wiring. The front BiConnect terminal of the QuickConnect plug-in system enables quick and safe connection to the phase busbar. Thanks to the flap protecting the labeling fields, the markings remain legible for a long time.

• Quick installation: The QuickConnect system eliminates the need to screw wires, shortening installation time.
• Safety: Constant spring pressure on the wire ensures a secure connection and minimizes the risk of accidents.
• Convenience: Easy replacement of the circuit breaker during service work without the need to disassemble other components of the distribution board.
• Space: Compact design and the QuickConnect system allow for efficient use of space in the distribution board.
• Versatility: Surface mounting and compatibility with various wire cross-sections (1-35 mm² solid, 1-25 mm² stranded).
