Switches
The Kyle® Types VR, VLR, or VRV motor-operated oil switches provide convenient three-phase general purpose (Types VR and VRV) and inductive load (Type VLR) remote control switching. The motor-operated actuator enables the switch to be remotely controlled with a manually operated SPDT switch or by other control means.
These economical, general purpose switches have a proven history of excellent performance servicing the utility industry for over thirty years. Reliable and dependable for various switching applications, these general purpose switches are the obvious choice.
Type VR and VLR switches are applicable to 14.4 kV applications. The Type VRV switch is applicable to 34.5 kV applications.
Type VR and VLR switches are differentiated from each other by their contact structures. Type VR switches have two sets of arcing and load-carrying contacts per phase. The Type VLR switch utilizes two bayonet-type moving contacts per phase operating within self-blast interrupters. This same type of contact structure is also used in the Type VRV switch with increased arc gaps for 34.5 kV applications.
A six-pin plug and receptacle are furnished for connecting the control circuits to the switch. Other standard equipment includes a contact-position indicator, an operations counter, a manual trip ring, and provision for manual closing. Accessories include a quick close feature, a manual trip and block switch, a four stage auxiliary switch, an operator cabinet heater, and low-voltage surge arresters for the externally connected control circuits.
