Protection against damage to the current transformer

All terminal points are made accessible immediately by rotating the captive terminal cover through 90°. At the same time, the current transformer is short circuited to protect it against damage if conductors are disconnected from the secondary side during active operation. The proven screw-connection technology ensures that electrical conductors are connected safely.
The rotatable cover secured in the housing brings you even more 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.

Variable mounting options

PACT current transformers come with various mounting options, depending on your requirements:

Typical installation of the current transformer directly onto the busbar with the included accessories
Current transformer screw connection on a mounting panel via the plug-on feet included
Mounting on DIN rails with snap-in adapters available as an option

Safe detection of current peaks

PACT current transformers enable you to measure larger current peaks safely without the risk of damage. This is because the PACT current transformers have been designed for a continuous nominal current of 120% of the primary nominal 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.

Increased electrical safety

The housing walls of PACT 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 current transformers enable a maximum rated insulation voltage of up to 1,000 V (L-N).
