Four-pole circuit breaker DX3 16kA, 100A 409363

Four-pole circuit breaker – reliable protection for your installation

This four-pole circuit breaker is a key element of every safe and efficient electrical installation. It provides effective protection against overloads and short circuits, guaranteeing user safety and minimizing the risk of failure. It is a solution for both professional installers and end-users who value reliability and peace of mind.

The circuit breaker is characterized by a rated current of 100A and a high short-circuit breaking capacity – 16kA at 400V AC and 32kA at 230V AC. This allows it to handle even demanding loads, ensuring stable operation of the entire installation. Characteristic C provides a delayed response to short-term current surges, which is particularly important when connecting devices with motors or other elements generating high inrush currents.

Design and installation – simplicity and functionality

The circuit breaker has been designed for easy mounting on a TH35 rail. Compact dimensions (installation depth 47 mm) allow installation even in limited space. A width of 6 modules makes it easy to fit into existing distribution boards. The cross-section of the connected multi-wire cable is 6-50 mm², and the single-wire cable is 6-70 mm², which provides great flexibility when selecting cables. The IP20 degree of protection provides basic protection against touch and ingress of solid objects.

Additionally, the circuit breaker has a simultaneously disconnectable N pole, which increases safety during installation maintenance and repairs. The possibility of flush mounting provides additional design options. Made of high-quality materials, it guarantees long-lasting and trouble-free operation in a wide range of ambient temperatures (-25°C to +70°C). Compliance with IEC 60947-2 and EN 60898 standards confirms its safety and reliability.
