Energy monitors uk stock a large range of current transformers to suit all switchboard instrumentation, kilowatt-hour meters and power-monitoring units. We have a whole host of great brands for CT's at the most competitive around the UK. The CT current transformers deliver at the secondary a current (0-5 A) proportional to the current measured at the primary. This means that they can be used in combination with measurement devices (switchboard instrumentation, kilowatt-hour meters, power-monitoring units, etc.). Some of our current transformers we stock include both moulded case and split core types with 1A or 5A secondaries, single phase CT's or three phase CT's, or if there is any specific CT's you require please do not hesitate on giving our sales team a call on 01244 288138 who will be more then happy to assist with any additional information or advice needed.
