HH15/QAS/QPS/QSS Changeover Switch
Note
• Mainly used in the distributing and motor circuit which has high short-circuit current, and acted as main switch or master switch infrequently operated by hand, it is particularly suitable in the relative high class with drawable low voltage complete equipment. • They provide safety isolation and protection against overcurrent for any low voltage electrical circuit.
• Standard: IEC/EN 60947-3. • Rated current: 125~3150A.
HH15/QAS/QPS/QSS
NH40S Changeover Switch
