3SHT-1231.KN 3-pin external rotary switch without grounding by SERW

The SERW 3SHT-1231.KN is a 3-pin external rotary disconnector without grounding, built in a row version D1 to standard E.ON Germany specifications with a height of 1820 mm. Rated for a voltage of 123 kV and a current of 3150 A, this high-voltage switching device features a short-circuit current capacity of 40 kA/1s and a peak withstand current of 100 kA. It incorporates C10-550 insulators with a creep distance of 3100 mm and a pole distance of 2800 mm. The assembly is supported by a galvanised frame with frame painting in RAL7033 and insulator flanges painted in RAL7033, while the high-voltage parts remain unpainted. Electrical connections are handled via aluminium flanges supply clamps measuring 200x100 mm, featuring an 8x014 mm hole pattern spaced 50x50 mm in accordance with DIN 46206-A2. Technical data adheres to Se 4587n/B, and dimensional drawing Se 2499N-1-2 specifies direct drive mounting on the frame. Note that E.ON standard requirements for Ir are 1250 A, 2500 A, and 4000 A, meaning drawing Se 2499N-1-2 does not list the 3150 A value directly but corresponds to this specific device configuration.
