LYC121 High Voltage Epoxy Resin Sensor for ABB Switchgear – Pillar Insulator Type Charged Display Sensor
The LYC121 is a high-precision charged display sensor specifically engineered for ABB switchgear and compatible high-voltage power distribution systems. Manufactured through a premium vacuum-cast epoxy resin process, this component functions as both a high-strength pillar insulator and a voltage detection unit. Its unique stepped-shed design provides superior creepage distance, while the triple-threaded metal inserts at the top ensure a secure and stable connection to the busbar. The LYC121 extracts real-time voltage signals to drive charged indicators and mandatory safety locking networks, making it an essential safety feature for preventing accidental entry into live compartments.
LYC121 High Voltage Sensor (Epoxy Resin Charged Display Sensor for ABB)
Product Overview
The LYC121 is a high-performance, pillar-type high-voltage sensor designed specifically for ABB switchgear and compatible power distribution systems. This sensor utilizes an internal capacitor core rod to extract voltage from live circuits, providing the necessary signal for charged state realization and safety locking networks. Beyond its sensing capabilities, its robust construction allows it to serve as a high-strength pillar insulator for supporting busbars and other electrical components.
