Compact circuit breaker MCCB KMCCB-RT-400A-4P KANLUX IDEAL TS 38257

Robust protection for electrical installations – MCCB 400A circuit breaker

This MCCB circuit breaker, with a rated current of 400A, provides reliable protection for your installation. Designed for use in 3+N systems, it effectively protects against the effects of overloads and short circuits. Adjustment of the thermal element allows you to adapt the circuit breaker's characteristics to the specific load, which is particularly important when starting devices with motors or other elements generating high inrush currents.

Construction and application

The circuit breaker is designed for mounting on a mounting plate and is characterized by an IP20 degree of protection, which ensures safety under normal operating conditions. Its construction based on connection blocks facilitates quick and secure cable connection. The rated insulation voltage Ui is 1000V, and the rated impulse withstand voltage Uimp is 8000V – these parameters guarantee high resistance to overvoltage and ensure long-term, trouble-free operation. The circuit breaker meets the requirements of category A, which means it is intended for protecting circuits with general-purpose loads.

Key features and benefits

• High short-circuit breaking capacity: The rated ultimate short-circuit breaking capacity Icu is as high as 65kA, and the rated service short-circuit breaking capacity Ics is 50kA – this ensures effective protection even in the event of serious disturbances in the network.
• Characteristic adjustment: The ability to adjust the thermal element (range 0.8-0.9-1xIn) allows for precise adaptation of the circuit breaker to the load characteristics.
• Versatility: Designed for operation in networks with a rated voltage of 380/400/415V and a frequency of 50Hz.
• Safety: Rated insulation voltage Ui 1000V and rated impulse withstand voltage Uimp 8000V guarantee a high level of safety.
• Solid construction: Made of high-quality materials ensures durability and reliable operation for a long time.
• Mechanical control type: Simple and proven control mechanism ensures easy operation and reliable performance.
• Warranty: Product covered by a two-year manufacturer's warranty from KANLUX IDEAL TS.

Thanks to these features, this circuit breaker is an ideal solution for both professional installers and end-users looking for reliable protection for their electrical installations.
