ZJR7-B Built-in Contactor Soft Starter

Description

Overview

The ZJR7-B is a soft starter for three-phase 220-480V, 50/60Hz squirrel-cage motors with an integrated bypass contactor. Its enclosure and higher-power dimensions are distinct from the ZJR7-E external-bypass series.

Control and protection

  • Independent control supply, LCD interface and selectable Chinese or English display.
  • Three switchable motor-parameter sets, PTC temperature-sensor input and RS485 communication.
  • Ten fault records and screw-fixed main terminals.
  • Starting and stopping settings must be adjusted for the actual load; the application table provides reference values.
