The Beluk compensation relay, part number 1231809 3TA092H2-IA18X-00, is a thyristor switch designed for switching capacitors in power factor correction systems. Operating at a mains voltage of 400 V and 50/60 Hz, this unit handles a rated current of 72 A and delivers a step power of 50 kvar at 400 V with the switch in the outer conductor. It features two-phase switching and accepts a control signal of 8 to 30 V DC. Built for vertical installation with natural air cooling (AN), it operates within a temperature range of -10 to 60 °C, requiring power reduction above 45 °C, and is rated for installation altitudes under 1000 m. The device measures 200 x 160 x 215 mm (H x W x D) and requires a maximum 160 mA slow-blow fuse. Please observe the circuit arrangements in the data sheet.
