Split-Core Current Transformers


The Electromagnetic Industries Model 500T and 501T split-core current transformers provide a low-amperage current output proportional to line current and are for use in energy management control and metering applications. These transformers are ideal for use as inputs to power monitors such as the endicator™ and current transducers such as Models 4CTV and 4CMA.These transformers are designed to be assembled around an existing insulated conductor without the need for dismantling the primary bus or cables. The portion of the transformers marked "This End Removable" can be disassembled and then reassembled around the conductors that require current monitoring.
