Overcurrent switch Icn=6000A 3P B 40A QuickConnect MBS340

Overcurrent circuit breaker for your installation – reliability and quick installation.

This three-pole circuit breaker with a rated current of 40A is a solid solution for protecting electrical installations. It is characterized by a high short-circuit breaking capacity of up to 6kA at 230V AC and 10kA at 400V AC, which guarantees effective protection against the effects of overloads and short circuits. Energy limitation class 3 and surge category III provide an additional level of safety.

The circuit breaker has been designed with ease and speed of installation in mind, thanks to the innovative QuickConnect system. It allows for screwless connection of wires, which significantly reduces installation time and minimizes the risk of errors. The BiConnect system with screw terminals further protects against incorrect wiring.

Construction features and application

The circuit breaker has a B tripping characteristic, which means it is ideal for circuits with devices with high inrush current, e.g. motors. Its compact dimensions (83.4 x 52.5 x 70 mm) and width of 3 modules allow for efficient use of space in the distribution board. The possibility of flush mounting increases installation flexibility.

Application:

• Protection of lighting circuits
• Protection of socket outlets
• Protection of circuits with electric motors (thanks to the B characteristic)
• Domestic and industrial installations
