Circuit breaker with thermal-magnetic trip unit DPX3 160 4P 25A 50KA 420131

### DPX3 Power Circuit Breaker – Reliable Protection for Your Installation

The DPX3 160 thermal-magnetic circuit breaker is an electrical protection device designed to protect circuits against overloads and short circuits. It provides effective protection for electrical installations in residential, commercial, and industrial buildings. The construction based on proven Legrand technology guarantees reliable operation and long service life.

Characteristics and Application

The DPX3 160, four-pole (4P) circuit breaker, with a rated current of 25A and a short-circuit breaking capacity of 50kA at 400V, is used in installations with a rated voltage of up to 690V. Its design allows for mounting on a TH rail, which simplifies and speeds up installation. The built-in undervoltage release further increases safety by protecting against the effects of voltage drops. The possibility of using a motor drive allows for remote control of the circuit breaker.

Application in main distribution boards, protection of power supply lines for high-power devices, protection against the effects of short circuits and overloads – these are just some of the areas where this circuit breaker will prove useful. Thanks to its high short-circuit breaking capacity (50kA), it is ideal for applications requiring a high level of safety.

Advantages and Construction Features

• High short-circuit breaking capacity: 50kA at 400V ensures effective protection even in the event of large short-circuit currents.
• Wide range of rated voltages: from 220V to 690V – versatility of application in various installations.
• Thermal-magnetic trip unit: provides precise and fast response to overloads and short circuits, protecting devices and the installation. The adjustment range of the overload trip unit is 20-25A, allowing it to be adapted to the specifics of the circuit.
• Possibility of mounting accessories: optional motor drive and auxiliary contacts expand the functionality of the circuit breaker.
• Solid construction: ensures durability and reliable operation even in harsh working conditions (IP30 protection).
• Safety: Equipped with a trip indication, it facilitates identification of the device status after protection activation.
• Screw connection: ensures a secure and durable connection of wires to the circuit breaker.
• Integrated undervoltage protection: additional layer of protection for sensitive electronic devices.

DPX3 circuit breakers are characterized by compact dimensions, which facilitates installation even in tight distribution boards. This makes them an ideal solution for both professional installers and end-users looking for reliable electrical protection.
