Power switch with thermal-magnetic trip unit DPX3 160 3P 100A 36kA 420085

Power circuit breaker – reliable protection for electrical installations

This three-pole power circuit breaker with a thermal-magnetic trip unit from the DPX3 series is a key element of every electrical installation, providing effective protection against overloads and short circuits. A rated continuous current of 100A and a high breaking capacity of up to 36kA at 400V, 50Hz guarantee stable and safe operation even in demanding conditions. The device is designed for mounting on a TH rail, which facilitates its installation and integration with the existing system.

Functionality and technical parameters

The DPX3 circuit breaker is characterized by a wide range of rated voltages from 220 to 690V, making it a universal solution for various applications. It has one normally open auxiliary contact, which can be used to signal the status of the circuit breaker or for remote control. A built-in trip indicator allows for quick identification of the device's status, and an optional motor drive enables remote switching on and off. The adjustable overload trip range (80-100A) allows for precise adaptation to the load characteristics, and the adjustable delayed short-circuit trip range (1000-1000A) ensures appropriate selectivity in the event of a short circuit.

• High breaking capacity: 36kA at 400V, 50Hz – guarantees effective circuit interruption in the event of a short circuit.
• Appropriate rated current: 100A – for most standard applications.
• Precise overload setting: range 80-100A – possibility of adaptation to the load.
• Quick mounting: on TH rail – easy integration with the switchboard.
• Protection: IP30 protection class – against access and solid objects.

Construction and application

The DPX3 circuit breaker has been designed with durability and reliability in mind. Made of high-quality materials, it ensures long-term trouble-free operation. Screw connection of the main contacts guarantees a solid and safe connection of the wires. The device is used in electrical installations of residential, commercial and industrial buildings, where effective protection against overloads and short circuits is required. It is an ideal solution for both professional installers and end-users looking for reliable and safe protection for their electrical installation. Additionally, the possibility of mounting on a DIN TH rail facilitates integration with existing distribution systems.
