Power switch with thermal-magnetic trip unit with built-in residual current device DPX3 160+BL.R 4P 100A 16kA 420035

Power switch with residual current device – comprehensive installation protection

This four-pole DPX3 160 power switch, with a rated current of 100A and a short-circuit breaking capacity of 16kA, is a reliable solution for demanding electrical installations. The integrated residual current device provides an additional level of safety, protecting against electric shock and equipment damage. This switch is designed for mounting on a TH rail, making installation and replacement easy.

Functionality and application

The DPX3 160 switch is a stationary device designed to protect circuits against overloads and short circuits. The built-in thermal-magnetic trip unit with adjustable setting range (80-100A) allows for precise adjustment to the load characteristics. In addition, the built-in residual current device with adjustable residual current (0.03 - 3A) and disconnection delay time (0 - 3s) increases the functionality of the device and allows for optimal protection depending on the specifics of the installation. This makes the switch suitable for use in residential, commercial and industrial buildings.

Construction and characteristic features

The switch is characterized by a solid construction and high quality workmanship. It has screw connections for the main conductors, allowing the connection of conductors with a cross-section of up to 70 mm². It is equipped with one normally open auxiliary contact and one changeover contact, allowing integration with control and signaling systems. The trip indicator informs about the operation of the protection, facilitating diagnosis of problems in the installation. The device meets the requirements of IEC 60947-2 standard and has a degree of protection IP30, ensuring its safe operation in various environmental conditions. The possibility of mounting on a DIN TH rail further increases installation flexibility. The integrated undervoltage release adds another layer of protection for sensitive devices.
