The ETH17 series fuse-type isolating switches are suitable for high short-circuit current circuits with a frequency of 50 Hz, a rated voltage up to 690 V and a conventional heating current up to 630 A. They are equipped with an arc extinguishing device and are capable of on-load operation. They are used as power switches, isolating switches and emergency switches, as well as for the protection of AC circuits.
The switches feature an attractive, innovative and streamlined design, and comply with the IEC60947-3 and GB 14048.3 standards.
