Overcurrent circuit breaker 6kA PL6-D6/1 286542

Overcurrent circuit breaker – reliable protection for electrical installations

This single-pole overcurrent circuit breaker from Eaton's xPole Home series, with a rated current of 6A and a short-circuit breaking capacity of 6kA, is a key element in protecting electrical circuits in residential and commercial buildings. Designed for effective protection against overloads and short circuits, it ensures safe operation and long-term reliability. Characteristic D makes it particularly useful where devices generating high inrush currents during start-up are present – for example, motors or transformers.

Functionality and application

The PL6-D6/1 circuit breaker is designed to protect wires and electrical devices with resistive or inductive load characteristics. Its compact design (1 module width) makes it easy to install in electrical distribution boards, and the universal connection terminals allow connection of solid and stranded conductors with a cross-section from 1 to 25 mm². The use of characteristic D means that the circuit breaker reacts with a delay to short-term current surges, which prevents unnecessary tripping of the circuit when starting devices with a motor. This is an ideal solution for installations powering devices requiring a high starting current.

Construction features and parameters

The circuit breaker is made of high-quality materials, which guarantees its durability and resistance to environmental conditions. It has a protection degree of IP20, which means protection against touching with a finger and against the ingress of solid objects larger than 12.5 mm. It is designed to operate at temperatures from -25°C to +75°C and at a frequency of 50-60 Hz. The rated insulation voltage Ui is 440V and the rated impulse withstand voltage Uimp is 4kV. Additional possibility of expansion with accessories (e.g. auxiliary contacts) increases its functionality and allows it to be adapted to individual installation needs. The energy limitation class is 3 and the surge category is III.
