The Beluk 1231809 (model 3TA092H2-IA18X-00) is a thyristor switch designed for switching capacitors with a stage output of 50 kvar at 400 V when the controller is in the outer conductor. This two-phase switching unit operates at a line voltage of 400 V at 50/60 Hz with a rated current of 72 A. It is controlled via an 8 - 30 V DC control signal. Featuring natural air cooling (ON), the device is built for vertical installation at an installation height of under 1000 m. The operating temperature range spans from -10 to 60 °C, with a power reduction required above 45 °C. Protection is rated at a maximum of 160 mA (slow). The compact dimensions of the 1231809 are 200 x 160 x 215 mm in height, width, and depth.
