Product Introduction

Product Overview

The PCS-924 is primarily used as T-zone protection and line overcurrent protection in 3/2 breaker configuration. When the line disconnector is closed, T-zone protection adopts three-side current ratio differential mode. When the line disconnector is open, two-side current differential protection plus two-stage overcurrent protection on the line side are activated. Among them, the PCS-924B is mainly used for small-zone short-lead protection and consists of four-side current differential protection.
