Circuit breaker DPX3 250 HP EL S1 4P 100 A 70 kA 423246

Robust power protection for demanding installations

The DPX3 250 HP EL S1 circuit breaker is a four-pole device designed to protect circuits with a rated current of 100A. The short-circuit breaking capacity of 70kA at 400V ensures effective protection against the effects of sudden overvoltages and short circuits, minimizing the risk of damage to the electrical installation. This solution is suitable for both commercial buildings and more extensive industrial installations.

Functionality and installation

The circuit breaker is based on a fixed mounting design, which guarantees stability and reliable operation. The location of the main circuit connections on the front side facilitates connection of the wires, and the bolt connection ensures a secure and durable connection. Two switchable auxiliary contacts increase the possibilities of integration with control and signaling systems. The circuit breaker is adapted to cooperate with an optional motor drive, which may be useful in applications requiring remote control.

Safety and operating parameters

The DPX3 250 HP EL S1 circuit breaker has an overload release setting range from 40 to 100A, allowing for precise adjustment to the load characteristics. The short-circuit release with a setting range from 150 to 1000A ensures a quick response in the event of a short circuit. The built-in trip indicator informs about the operation of the protection, making it easier to locate the problem. The IP30 degree of protection protects against touch and the ingress of solid objects, ensuring safe operation. Please note that the device does not have a built-in short-circuit to ground protection or the possibility of mounting on a TH rail.
