Overcurrent circuit breaker 6kA PL6-D40/3N 165044

Overcurrent switch 3P+N – reliable installation protection

This three-pole switch with an additional neutral pole (3P+N) is a key element of every safe electrical installation. Designed to protect circuits against overload and short circuit, it ensures stable operation of devices and minimizes the risk of failure. It is characterized by a high short-circuit breaking capacity – as much as 6kA, which guarantees an effective response in emergency situations. Manufactured by the renowned company Eaton, it is synonymous with quality and durability.

Functionality and technical parameters

The PL6-D40/3N switch with a rated current of 40A and characteristic D is ideal for installations requiring protection against sudden current surges, e.g. when connecting devices with electric motors. Characteristic D allows for momentary overloads without unnecessary tripping of the circuit, which is particularly important for devices with high starting current. Rated voltage of 230V and compliance with EN 60898 and IEC 60947-2 standards ensure safety and reliability. In addition, the possibility of mounting additional equipment allows the switch to be adapted to specific installation needs.

Installation and application

The PL6-D40/3N switch is designed for mounting on a TH35 rail. Its compact dimensions (4 module width) allow for efficient use of space in the distribution board. The cross-section of the connected solid or stranded wire up to 25 mm² provides flexibility in connecting different types of wires. Protection class IP20 protects against finger contact, which increases safety. This switch finds application in residential, commercial and industrial buildings where reliable protection of the electrical installation against overloads and short circuits is required. At the same time, the disconnectable N pole increases safety during maintenance and repair of the installation.
