Circuit breaker DPX3 160 3P 125A 16kA 420006

Three-pole circuit breaker DPX3 160 – reliable protection of electrical installations

The DPX3 160 circuit breaker is a compact device designed to protect electrical circuits against overload and short circuit. Designed by Legrand, it is an integral part of energy distribution systems in residential, commercial and industrial buildings. Its solid construction and high short-circuit breaking capacity (16kA at 400V) guarantee safety and continuity of power supply. The device is mounted on a TH rail, which facilitates installation and replacement.

Characteristics and application

The DPX3 160 circuit breaker with a rated current of 125A, equipped with a thermal-magnetic trip unit, provides effective protection against the effects of overloads and short circuits. This protects both the electrical installation itself and the devices connected to it. The built-in trip indicator facilitates quick identification of the circuit breaker status and location of any failure. The possibility of mounting additional auxiliary tripping contacts (1 pc) expands the functionality of the device, allowing integration with control and signaling systems. The integrated undervoltage release further increases the safety of the installation.

Circuit breakers from the DPX3 series are widely used in:

• Electrical switchboards
• Distribution boards
• Lighting installations
• Socket circuits
• Power supply for electric motors (after proper selection of the trip unit characteristics)

Advantages and design features

• High short-circuit breaking capacity: 16 kA at 400 V provides effective protection even in the event of high short-circuit currents.
• Three-pole design: Provides comprehensive protection of the entire three-phase circuit.
• TH rail mounting: Enables quick and easy installation and replacement of the circuit breaker.
• Thermal-magnetic trip unit: Protects against overloads and short circuits, ensuring selective operation. The setting range of the overload trip unit is 100-125A, and the delayed action 1250-1250A.
• Trip indicator: Facilitates identification of the circuit breaker status and location of failure.
• Protection class IP30: Provides protection against accidental contact and against the ingress of solid objects larger than 2.5 mm.
• Expandability: Additional auxiliary contacts expand the functionality of the device.
• Solid screw connections: Ensure a secure and durable connection of the wires.
• Rated voltage range: A wide range of operating voltages from 220 to 690V allows for use in various installations.

The device is made of high-quality materials, which guarantees its durability and reliability even in difficult working conditions. It meets the required safety standards, ensuring safe operation of the electrical installation.
