Circuit breaker DPX3 630 TM 3P 630A 36kA 422004

DPX3 630 Power Circuit Breaker – reliable installation protection

The DPX3 630 TM circuit breaker is a three-pole device designed to isolate and protect electrical circuits in residential, commercial and industrial buildings. It provides effective protection against overloads and short circuits, guaranteeing safe operation and minimizing the risk of failure. The circuit breaker design allows it to work with blocks or residual current devices, expanding the functionality of the protection system.

Characteristics and application

The DPX3 630 TM circuit breaker is characterized by a high short-circuit breaking capacity of 36 kA at 400 V, making it an ideal solution for installations with high power demand. The continuous rated current of 630 A allows its use in circuits powering devices with significant current draw. The built-in undervoltage release further increases safety, protecting against the effects of voltage drops in the network. The device is mounted by screw connection, which ensures a stable and reliable connection of the wires.

• Applications:
  • Main and distribution switchboards
  • Protection of motor power circuits
  • Protection of electrical installations in public buildings
  • Uninterruptible power supply (UPS) systems
  • Industrial installations

Key features and benefits

• High short-circuit breaking capacity (36 kA): Ensures quick and effective disconnection of the circuit in the event of a short circuit, minimizing damage to equipment and the risk of fire.
  • Wide adjustment range of the overload release (504 – 630 A): Allows precise adjustment to the load characteristics, ensuring optimal protection against overloads.
  • Built-in undervoltage release: Protects devices from damage caused by too low a supply voltage.
  • Possibility of mounting auxiliary contacts: Allows expanding the functionality of the circuit breaker with status signaling or remote control. Available are normally open contacts (2 pcs) and changeover contacts (2 pcs).
  • Durable construction: Made of high-quality materials, guarantees long-lasting and trouble-free operation.
  • Compliance with IEC/EN 60947-2 standard: Confirms compliance with strict safety and quality requirements.
  • Adjustable range of delayed short-circuit release (3150 - 6300 A): Allows adaptation to specific installation conditions, especially with devices generating high inrush currents during start-up.

Construction and assembly

The DPX3 630 TM circuit breaker is a fixed device, designed for mounting in electrical switchboards. Screw connection ensures a secure and durable connection of the wires. Thanks to its compact dimensions, the circuit breaker easily integrates with the existing electrical infrastructure. The IP30 degree of protection provides protection against accidental contact and against the ingress of solid objects larger than 2.5 mm.

The circuit breaker is supplied complete with flat screw terminals and insulating terminal partitions, which facilitate assembly and ensure safe use. The possibility of sealing the settings prevents unauthorized changes to the device's operating parameters. Additionally, there is an option to mount a motor drive for remote control of the circuit breaker.
