Application
The products are suitable for making and breaking power turn-circuit of voltage 415V, frequency 50/60Hz, rated current up to 1600A, acting as power switch, isolating switch and emergency switch. Because of special system of arc-contact and main-contact, HGL operates with high efficiency, safety and reliability, complying with IEC60947-3.Rotational operation and direct mechanical connection between handle and moving contact, on-off handle makes contact break and indicating place of contact. Panel and independent type installation are fitted with HGL.
