Distribution- CSC-211 Multifunction Protection IED

Description

Product Detail

Overview
CSC-211 Multifunction Protection IED is versatile IED designed for protection, control and monitoring of feeders. The devices can be used for line protection in networks that are grounded, low-resistance grounded, ungrounded, or of a compensated neutral point structure. It is able to supervise primary apparatus such as circuit breakers and disconnectors.
