A high speed whip type air switch attachment used to interrupt transformer magnetizing and line charging current. It can be applied on vertical break and side break switches in both standard and slant style configurations.
- Easy and fast installation
- High tip speed
- Maximum versatility. It can be mounted on virtually any vertical or side break disconnect switch
- Maintenance free other than periodic inspection
- Maximum reliability. Interruption is independent of switch opening speed
- Spring loaded
- Heat-treated tapered stainless steel whip
- Universal mounting
- Long operating life
