Description
TNAL air insulated switch disconnectors (load break switches) and TNALF fuse switch disconnectors (load break switches) are designed as key breaking elements for applications in air insulated switchgears and transformer compact substations. Their unique electric arc extinguishing and high switching capacity designs enable them an attractive solution.
TNALF series combine advantages of switch disconnectors and fuses. They ensure control over the full range of overload and short circuit currents. They can be applied for switching and protecting distribution transformers, motors and capacitor banks.
The TNAL/TNALF switch disconnector is based on a modular principle. The basic unit consists of a frame with insulators and current carrying parts. There are two different types of operating mechanisms: snap action mechanism type K or stored spring energy mechanism type A. The operating mechanisms can be mounted on the frame. Fuse bases type F, with or without fuse tripping mechanism, and an earthing switch type E/EB, suitable for both direct mounting and free standing components, complete the basic equipment of a switch disconnector. These modules can be easily configured upon customer request. Accessories, such as shunt trip, under-voltage release, auxiliary switches, motor operation and various systems for manual operation can easily be added.
