Overcurrent switch Icn=6000A 1P B 20A QuickConnect MBS120

Single-pole circuit breaker with a rated current of 20A and B characteristic, providing reliable protection for electrical installations. Designed for quick installation and convenient operation, it is suitable for both domestic and commercial installations. The rated short-circuit breaking capacity (Icn) is 6kA at 230V AC, guaranteeing effective protection against overloads and short circuits.

Features and application

This circuit breaker is part of the QuickConnect system, which significantly speeds up the installation process. Instead of traditional screw connections, wires can simply be plugged into the terminals, saving time and increasing safety. The system includes apparatus, enclosures and busbars, allowing for comprehensive space management in the distribution board. The circuit breaker has an IP20 protection rating, which means protection against finger contact and solid objects larger than 12.5 mm. Flush mounting facilitates aesthetic integration into the surroundings.

Advantages for the installer and user

• Quick installation: The QuickConnect system eliminates the need to screw wires, reducing installation time by up to several dozen percent.
• Safety: Constant spring action on the wire ensures a secure connection and increased protection against contact.
• Convenient servicing: Easy replacement of the circuit breaker without the need to disassemble other elements of the distribution board facilitates service work.
• Compact dimensions: 1 module width allows for efficient use of space in the distribution board.
• Versatility: Possibility to connect single-wire conductors (1-35 mm²) and multi-wire conductors (1-25 mm²) ensures compatibility with various types of installations.
• Increased protection: Energy limitation class 3 and surge category 3 provide high resistance to interference in the electrical network.
• Clarity: Transparent flap protects the label fields from damage, allowing for clear marking of the circuit breaker function.

Construction and parameters

The circuit breaker is made of high-quality materials, guaranteeing its durability and reliability. It has a rated insulation voltage Ui of 500V and a rated impulse withstand voltage Uimp of 4kV. It operates in the frequency range of 50-60 Hz and is designed to operate in an ambient temperature from -25°C to 70°C. The use of a rear BiConnect terminal with screw connection provides additional protection against incorrect wire connection. The front BiConnect QuickConnect plug-in system terminal ensures a quick and safe connection to the phase busbar.
