The proven screw-connection technology ensures that electrical conductors are connected safely. All four terminal points become quickly accessible with just a 90° rotation of the housing cover. The cover, that can be rotated and that is secured in the housing, brings you two advantages: on the one hand, it cannot be lost, and secondly, by turning it back to its original position you immediately receive visual confirmation that it is safe to touch.
PACT current transformers come with various mounting options, depending on your requirements:
PACT current transformers enable you to measure larger current peaks safely without the risk of damage. This is because the current transformers are designed for a continuous nominal current that is 120% of the primary rated current strength. This means that for a rated current that is 1.2 times greater, a PACT current transformer with a specified rated power of 10 VA actually delivers 14.4 VA – and on a continual basis.
The housing walls of PACT MCR current transformers have a 14 mm overlap, thus offering better electrical safety than required by the standard. These overlaps significantly increase the air clearances and creepage distances and thereby prevent electrical sparkovers from the primary to the secondary side.
The rated insulation voltage of conventional 720 V transformers is just 416 V (L-N). PACT MCR current transformers enable a maximum rated insulation voltage of up to 1000 V (L-N).
