DPX3 125 HP Circuit Breaker – Reliable Protection for Electrical Circuits
The DPX3 125 HP is a three-pole thermal-magnetic circuit breaker designed to protect electrical installations against overloads and short circuits. With a rated continuous current of 50A and a high short-circuit breaking capacity of 70kA at 400V, it ensures reliable and safe operation under demanding conditions. This robust solution is ideal for both professionals and end-users seeking dependable protection.
Functionality and Applications
This circuit breaker is widely used in commercial and industrial buildings, as well as in residential installations with high power demands. Thanks to the adjustable settings for the thermal overload trip (40–50A) and magnetic short-circuit trip (400–600A), it can be precisely tuned to match the load characteristics. It features two reversible auxiliary contacts, enabling seamless integration with control and signaling systems. Installation is performed via screw terminals, ensuring secure and durable conductor connections.
Key Features and Benefits
- High short-circuit breaking capacity (70kA): Ensures rapid and effective response during short-circuit events, minimizing the risk of damage to the installation and connected equipment.
- Adjustable overload current setting (40–50A): Allows customization to specific circuit requirements, preventing nuisance tripping.
- Three-pole design: Ideal for protecting three-phase electrical circuits.
- Trip indicator: Facilitates quick identification of the breaker’s status and efficient fault diagnosis during outages.
- Robust construction: Fixed mounting ensures stability and long-term durability.
- Wide rated voltage range (220–690V): Enables use across diverse electrical installations.
- IP30 protection rating: Protects against accidental contact and ingress of solid objects larger than 2.5 mm – suitable for most indoor environments.
- Two reversible auxiliary contacts: Enhances functionality by enabling integration with other automation systems.
The DPX3 125 HP circuit breaker is an investment in the safety and reliability of your electrical installation. Its advanced features and solid construction guarantee long-term, trouble-free operation.
