Three-pole circuit breaker DPX3 250 – Reliable protection for electrical installations
This automatic circuit breaker from the DPX3 250 series is a robust solution for protecting electrical circuits. Designed for operation in systems with a rated voltage range of 230 to 690 V, it provides effective protection against overloads and short circuits. A rated continuous current of 100A and a high short-circuit breaking capacity of 100 kA at 400 V ensure safety even under demanding conditions.
The DPX3 breaker features versatility: it includes two reversible auxiliary contacts that enable integration with control and signaling systems. The adjustable thermal trip setting range of 80 to 100 A allows precise tuning to match the load characteristics, ensuring the device responds appropriately and minimizes unnecessary tripping.
Construction and Installation
The breaker is designed for fixed mounting and features bolted connections for main conductors, ensuring secure and durable connections. The IP30 protection rating guards against accidental contact and ingress of solid objects, making it suitable for most industrial and commercial environments. An on/off indicator facilitates quick identification of the device’s status. Additionally, an optional motorized drive enables remote operation, which is especially useful in automated systems.
The device provides a rated continuous current of 100A and a short-circuit breaking capacity of 100 kA at 400 V and 50 Hz. It features three poles and allows adjustment of the thermal trip setting from 80 to 100 A and the magnetic trip setting from 500 to 1000 A. The IP30 protection rating ensures protection against contact and ingress of solid objects, while two reversible auxiliary contacts expand integration possibilities with other systems.
The device is supplied with built-in protection, eliminating the need for additional components. Its robust construction ensures reliable long-term operation, and high manufacturing quality guarantees safe operation.
