Current transformers deliver to the secondary a standard current proportional to the primary current and adapted to the rating of the associated device.They are equipped as standard with removable terminal covers and double terminals allowing the secondary to be short-circuited without any risk.
They are mounted using two screw-on metal brackets or, in certain cases, by a clip-on DINrail fastener. The connections are made by screws or by fast-on terminals.
