RITZ DIN-Design Current Transformers
RITZ indoor medium-voltage current transformers to the DIN 42600 standard dimensions, interchangeable in switchgear: 3.6 to 40.5 kV, primary currents up to 4,000 A.
Product Overview
DIN-design current transformers follow the DIN 42600 dimensions and fixing points, so they are interchangeable in medium-voltage switchgear. RITZ offers small (part 4), large (part 5) and narrow (part 8) designs from 3.6 to 40.5 kV.
The representative GSWS 12/24 is a narrow block-type CT to DIN 42600 part 8: fully cast in brown epoxy resin, with 1 or 2 cores (more on request) and metering and protection classes. The data below are for the GSWS 12/24.
