Three-pole switch DX3 16 kA 100 A 409281

Safety and reliability in your electrical installation

This three-pole overcurrent circuit breaker from the DX3 series is a key element in protecting electrical circuits. Designed to operate at 400V, it provides effective protection against overloads and short circuits, protecting both devices and the installation. A rated current of 100A makes it ideal for securing circuits with higher power consumption.

Construction and mounting

The circuit breaker is designed for flush mounting, providing an aesthetic appearance of the installation. A width of 4.5 modules allows for easy adaptation to existing switchboards. Mounting is done on a standard TH35 rail. Solid construction and high quality workmanship guarantee long-lasting and trouble-free operation. The possibility of additional equipment allows you to adapt the circuit breaker to specific installation needs.

Characteristics and parameters

The C tripping characteristic means that the circuit breaker reacts more slowly to short current surges, therefore it tolerates starting devices with a motor or other loads with a high inrush current. The rated short-circuit breaking capacity (Icu) is as high as 16 kA at 400V and 32 kA at 230V, providing a high level of safety in the event of a failure. The circuit breaker meets the standards EN 60898 and IEC 60947-2, confirming its compliance with applicable safety standards. The cross-section of solid conductors from 6 to 70 mm² and stranded conductors from 6 to 50 mm² provides great flexibility when connecting different types of conductors. The degree of protection IP20 provides protection against finger contact, but does not protect against the effects of water. The ambient temperature in operating conditions is in the range of -25°C to 70°C, allowing it to be used in various environmental conditions.
