Indoor AC Hv Load Switch

Model NO.: Fn3-12 Series Type: load switch Installation: Fixed Structure: Moulded Case Circuit Breaker Function: Overcurrent Protection, Circuit-Breaker Failure P Trademark: VILLE Origin: Ningbo China Breaking Capacity: High Voltage Circuit Breakers Operation: Electric Type Speed: Normal Type Circuit Breaker Arc-extinguishing Medium: Air Certification: CE, ISO9001-2000, CCC, VDE, UL, CB Specification: IEC standard General:
FN3-12 series indoor AC HV load switch is suitable for AC 50Hz, 10kV three-phase power system for breaking and closing load current, also for breaking and closing long no-load line and Capacitor bank capacitance current. Load switch with fuse(FN3-12R\FN3-12R/S)can break short-circuit current and protect switches.
The load switch can be fitted with CS3 and CS2 type manual operating mechanisms.

Characteristics:

FN3-12 series indoor AC HV load switch has a similar appearance as common indoor AC HV load switches with frame containing drive mechanism under the switch. There are six insulators on top of the frame, the upper three of them work as support and cylinder. The piston is installed inside the cylinder and driven by main shaft. The lower three of them work as support. Both the upper and lower insulators have contact holder that is the three-phase circuit input and output terminal. Conducting parts are made up of switch blade and contact holder. The switch blade and lower contact holder are fixed by six butterfly springs. At the end of switch blade there is arc contact. The upper contact holder is main static contact.
