The AMCT-RJ-36-3 is an easy-wire, three phase current transformer with 3 split core CTs, giving the unit wide range of primary current input and saving labour of installation. The S1 and S2 of each phase are integrated together in same wire leading to RJ12 port.
The AMCT-RJ range of split core current transformers have been specifically designed by Autometers Systems Ltd to be small and easy to open and yet maintain the accuracy required for kwh meters, the quick release CLIP makes this current transformer the easiest and quickest to fit around cables.
The benefit of a split core current transformer is that it can be placed into position easily and without disturbing or disconnecting the main cables it is monitoring.
The AMCT-RJ range of Split core current transformers is supplied with a 1.0 metre length of cable from each c.t, colour coded to indicate L1, L2 and L3 and a further 5 meters from the connection of the three individual ct cables to the meter ( see diagram).
The current transformers are manufactured with the correct cable size and a 5 metre length to ensure an accuracy level suitable for a class 1.0 meter.
Before fitting any current transformers the circuit must be totally isolated. Under no circumstances should you try and install current transformers to a live circuit.
