Power switch with thermal-magnetic trip unit DPX3 160 3P 63A 16kA 420003

DPX3 Power Circuit Breaker – Reliable Protection for Electrical Installations

The DPX3 160 power circuit breaker is a three-pole device designed to protect electrical circuits against overloads and short circuits. A rated continuous current of 63A and a high short-circuit breaking capacity of 16kA guarantee effective protection in demanding applications. The device's construction, based on a thermal-magnetic trip unit, provides both a quick response to sudden current surges and protection against prolonged overloads. Mounting on a TH rail simplifies installation and integration with existing systems.

Functionality and Application

The DPX3 160 circuit breaker finds application in a wide range of electrical installations – from commercial buildings, through industrial facilities, to home installations with higher power requirements. Thanks to the possibility of mounting on a DIN TH rail, it is ideal for building switchboards and distribution boards. The built-in trip indicator allows for quick identification of the device's status and location of any problems in the installation. Additionally, the presence of one normally open auxiliary contact enables connection of a circuit breaker status indicator.

Characteristics and Benefits

• High short-circuit breaking capacity (16kA): Ensures effective protection of the installation even in the event of large short-circuit currents.
• Overload trip unit setting range (50.4 – 63A): Allows precise adjustment to the load characteristics, minimizing the risk of unnecessary tripping of the device.
• Thermal-magnetic trip unit: Protects against both overloads and short circuits, providing comprehensive protection of the installation. Characteristic C allows it to react more slowly to short current surges, therefore it tolerates starting motors well.
• TH rail mounting: Simplifies and speeds up installation and ensures stable mounting of the device in the switchboard.
• Protection degree IP30: Provides basic protection against accidental contact and against the ingress of solid objects larger than 2.5 mm.
• Possibility of mounting a motor drive: Expands the functionality of the circuit breaker, enabling remote control and automation of processes.
• Integrated undervoltage release: Additional layer of protection for sensitive devices.

The DPX3 160 circuit breaker is a solid and reliable solution for professionals and users looking for effective protection of their electrical installations. Its advanced features and high quality of workmanship guarantee long-lasting and safe operation. The device is manufactured by Legrand Polska Sp. z o.o., which confirms its compliance with applicable safety standards (has the CE marking).
