Product Description

The KT28-63R contactor integrates a 63A thermal relay, designed for robust industrial applications such as manufacturing, energy systems, and heavy machinery. Featuring 3 input and 2 output channels, it directly interfaces with up to 5 expansion modules, supporting communication via RS-485 or Modbus protocols. Operating within a wide voltage range of 24-440V AC/DC and a temperature tolerance of -20°C to +60°C, it ensures reliability in harsh environments. As a KT28 relay replacement, it offers enhanced durability and simplified installation. Notable advantages include high overload protection accuracy and compatibility with legacy systems, while its larger footprint may require panel adjustments. The device lacks a screen or battery, focusing on core functionalities like motor control with a rapid response detection range of <10ms for fault conditions.
