Functionality and safety in one

The DPX3 250 HP breaker features precise operation of its thermal-magnetic trip units. The overload trip is adjustable between 80-100A, allowing customization to specific installation requirements. The short-circuit trip, with a setting range of 500-1000A, ensures rapid response in the event of a short circuit. The built-in trip indicator simplifies identification of the device’s status and helps locate potential faults.

This breaker has an IP30 protection rating, providing protection against contact and ingress of solid objects larger than 2.5 mm. Main terminal connections are made via bolted connections, ensuring secure and durable wiring. The 70kA short-circuit breaking capacity at 400V ensures effective protection even under high fault current conditions.

Installation and compatibility

The DPX3 250 HP breaker is designed for mounting on TH35 rail or mounting plates inside electrical panels. Optional motorized operation enhances user convenience, especially in hard-to-reach locations. The device is supplied with flat screw terminals accepting conductors up to 120mm² (stranded) or 150mm² (solid). It is compatible with DPX3 auxiliary accessories, enabling expansion of the protection system’s functionality.
