SASK 41.4, SASK – Protective current transformer, product image

Description:

Protection current transformers with circular primary conductor conduit for primary nominal currents from 100 A to 300 A, secondary nominal current 5 A, 2 A or 1 A, in protection classes 5P5 and 10P5.

Protection current transformers are used to control protective relays that have the role of disconnecting downstream circuits in the event of a current surge. Proportional transmission behaviour of the transformer up to a multiple of the nominal current is required for the reliable function of this relay. The dimensioning of this transformer design safeguards proportional current transmission up to a multiple of the nominal current.

Optionally, the supply of primary conductor bars (electrolytic copper, nickel-plated) corresponding to the bar window, including screws DIN 933, complete with nuts, washers and lock washers for mounting in busbars or similar is possible. determined by the protection class.
