JinZhi Technology LPC-3532 Low Voltage Motor Comprehensive Protection and Control Device

1. Product Purpose and Features
LPC-3531/3532 are both low voltage motor comprehensive protection and control devices, providing various start and
stop control functions, protection, and measurement and control functions for low voltage motors (380V). Among them, the LPC3531 device's current acquisition is configured with standard CT (as a secondary
CT, available in 1A and 5A ratings, using terminal wiring); the LPC3532 device's current acquisition is configured with ** CT (can serve as
a primary CT, available in various ratings such as 1A, 5A, 25A, 100A, 150A, 250A, 400A, with cable through-core wiring). For the structure, features, technical data, dimensions, etc., of the LPC-3531/3532
devices and various specifications of CT, please refer to the "LPC-3500 Series Low Voltage Comprehensive Protection and Control Device Overview". This device can be optionally equipped with the LPC-3597 display operation module to achieve related display and operation functions.
