DPX3 630 S2+P 3P 630 A 50 kA circuit breaker 422110

DPX3 630 S2+P Circuit Breaker – Reliable Protection for Electrical Installations

This three-pole DPX3 630 S2+P power breaker, rated at 630A and with a short-circuit breaking capacity of 50 kA, is a robust solution for electrical installations requiring high reliability and safety. Designed for low-voltage line protection, it performs excellently in industrial and commercial applications. Equipped with an adjustable electronic trip unit, it provides precise protection against overloads and short circuits.

Functionality and Applications

The DPX3 630 S2+P breaker is a fixed-mount device designed to work with residual current devices (RCDs) or auxiliary modules. Its screw-terminal connections ensure secure and durable wiring. With a rated continuous current of 630A, it safely handles high-load installations, while the wide adjustable overload trip range (252–630A) allows fine-tuning to specific application requirements. This breaker is ideal for protecting circuits with high-inrush motors, thanks to its characteristic C, which permits temporary current surges above rated values without unnecessary tripping.

Advantages and Key Features

• High short-circuit breaking capacity: 50 kA at 400V/50Hz ensures effective protection against fault currents.
• Adjustable electronic trip unit (S2): Enables precise setting of protection parameters (Ir, tr, Isd, tsd) to match load characteristics.
• Wide rated voltage range: From 220V to 690V ensures universal compatibility across diverse installations.
• Built-in undervoltage release: Additional protection against voltage dips in the network.
• Optional motorized operating mechanism: Facilitates remote control of the breaker.
• Trip indicator: Quick identification of breaker status – whether it tripped and why.
• Compliance with IEC/EN 60947-2 standard: Safety and reliability certified.
• Two changeover auxiliary contacts: Enable connection of status signaling or control of other devices.
• Protection rating IP30: Protects against finger contact and ingress of solid objects larger than 2.5 mm.

The DPX3 630 S2+P breaker is an investment in the safety and reliability of your electrical installation – trusted by professionals and end-users alike.
