F10-16III-LD Rotary Auxiliary Switch For High Voltage Circuit Breaker

F10 series auxiliary switches are mainly used as opening and closing signal control and interlocking protection contacts in the control circuits of various high-voltage circuit breakers and high-voltage isolating switch operating mechanisms. They can also be used as transfer switches and combination switches. They have been widely used in the secondary circuits of vacuum circuit breakers, load switches and spring operating mechanisms such as VS1 (ZN63), ZN12, 3AF, ZN65, FZN25, CT19, CTD, etc.

Product structure and performance characteristics 

F10 auxiliary switch is a rotary auxiliary switch, and the lead-out end adopts fully insulated terminal wiring. The contact is a flat sliding contact, and the moving contact consists of two contact pieces, without a fixed gap and a contact seat, so the contact pressure of each pair of contacts can be consistent. This product is assembled from modular switch units, and the number of contact sections can be arbitrarily determined according to user requirements. The entire switch is small in size, simple in structure, flexible in operation, safe and reliable.

Use environment and installation conditions
1. Altitude not exceeding 2000 meters;
2. Ambient temperature -10℃~+40℃;
3. Relative humidity: When the maximum temperature is +40℃, the relative humidity of the air shall not exceed 50%, and higher relative humidity can be allowed at lower temperatures.
4. The installation category (overvoltage category) is Ⅱ (load level).
