Overview

The Socomec CT automatic short-circuiter (SKU: 49900521) is a dedicated device for protecting people and equipment from hazards arising from the opening of a Current Transformer (CT) secondary circuit. This unit operates across a frequency range of 45-400 Hz and is rated for 5A protection. It adheres to IEC 60947-4-1 standards and functions as a short-circuit protection device for contactors, explicitly excluding motor protection via thermal overload relays. The device supports a rated operational voltage (Ue) up to 500 V AC and utilizes gG type fuses. It offers a rated short-time withstand current (Icw) of 1300 A at 1 second and a maximum breaking capacity of 2000 A at 440 V with a cos φ of 0.45. Power dissipation per pole is 12 W (AC-1), and the maximum electrical switching frequency is 300 cycles/h (AC-1, AC-3). Manufactured in Italy.
