Circuit breaker DPX3 630 TM 3P 250A 36kA 422000

Three-pole switch – reliable installation protection

The DPX3 630 TM switch is an advanced device designed to protect electrical circuits from overloads and short circuits. Intended for both residential and industrial applications, it ensures safety and continuity of power supply. A rated continuous current of 250A and a high short-circuit breaking capacity of 36kA guarantee effective protection even in demanding conditions.

Construction and functionality

The DPX3 630 TM switch is characterized by a solid construction and ease of installation. The device is permanently mounted and has screw connections for the main conductors, ensuring a secure and durable connection. It has a built-in undervoltage release, which further increases the safety of the installation. The availability of an optional motor drive allows remote control of the switch, which is particularly useful in automatic energy management systems. The trip indicator allows for quick identification of the device status and the causes of any failure.

Application and benefits

This three-pole switch will find application in:

• Main distribution boards: as a protective element for the entire electrical installation of the building.
• Motor supply circuits: the C characteristic allows it to react more slowly to short current surges, so it tolerates starting devices with a motor well.
• Industrial installations: where high reliability and the ability to switch off large short-circuit currents are required.
• Residential buildings: providing protection against overloads and short circuits in circuits with high loads.

Using the DPX3 630 TM switch translates to:

• High safety: protection against electric shock and fire caused by short circuit or overload.
• Long-term operation: solid construction and high-quality materials ensure reliable operation for a long time.
• Easy installation: simple construction facilitates installation and maintenance of the device.
• Flexibility: the possibility of using an optional motor drive expands the functionality of the switch.
• Compliance with standards: the device meets applicable safety standards, which guarantees its proper operation and compliance with regulations.

Additional information

• Overload release setting range: 200-250A – allows precise adjustment to the load characteristics.
• Rated short-circuit breaking capacity Icu at 400V, 50Hz: 36kA – provides effective protection against the effects of short circuits with high energy.
• Degree of protection IP30 – protects against accidental contact and the ingress of solid objects larger than 2.5 mm.
• Auxiliary normally open (2 pcs) and changeover (2 pcs) contacts are available, which allow integration with control and signaling systems.
