The RI-CT250 Series forms part of a family of solid core three-phase moulded case current transformers from Rayleigh Instruments.
These transformers are suitable for monitoring current flow in commercial, industrial or utility applications. They are designed to connect any standard metering or relay product requiring a 5A output and are available with Primary current input ranges from 630A to 1600A.
The RI-CT250 Series have been designed to fit a standard moulded case breaker size and are supplied with DIN rail clip, busbar mounting clamp and fixing feet. They also have clear markings moulded into the case to indicate the correct direction of primary current flow to minimise installation errors.
