Compact circuit breaker MCCB KMCCB-RT-125A KANLUX IDEAL TS 37281

Compact circuit breaker for electrical installation protection

This MCCB-RT-125A compact circuit breaker from KANLUX IDEAL TS is a reliable device designed to protect electrical circuits against overloads and short circuits. It is a key element of every safe and efficient installation, both in residential and commercial buildings. The design with adjustable thermal release allows you to adapt the tripping characteristics to the specifics of the load, which increases its versatility.

Functionality and technical parameters

This circuit breaker is characterized by a rated current of 125A, making it suitable for protecting circuits with medium and high power consumption. Adjustment of the thermal release in the range of 0.8-0.9-1xIn allows for precise setting of the tripping threshold, minimizing the risk of unnecessary tripping during short-term current surges – for example, when starting motors. The rated insulation voltage Ui is 800V, and the impulse withstand voltage Uimp is as high as 8000V, which guarantees high resistance to overvoltages. The circuit breaker has a protection degree of IP20, which means protection against contact with fingers and solid objects larger than 12mm.

Installation and application

Installation is done on a mounting plate using a connection block, which ensures quick and secure connection with the wires. The utilization category A indicates the versatility of the device – it is suitable for protecting lighting circuits, socket circuits and other electrical energy consumers. The rated operating voltage Ue is 380/415V and 220/230V, which allows its use in single-phase and three-phase installations. Additionally, this circuit breaker has a short-circuit breaking capacity Icu of 36kA at 220/230V AC and 25kA at 380/415V AC - an important parameter for ensuring safety in the event of a short circuit. The device is three-pole.
