Option Option Code Letter Availability Description
Drive Input Circuit
B, G
UL Type 1
UL Type 3R
For a 3-contactor bypass that removes power from the drive, select option (B). Drive service switch that removes power from the drive, select option (G).
Output Reactor
K
UL Type 1
UL Type 3R
No form of output impedance is normally required. A 5% load reactor, option (K), is available if additional output impedance is desired (usually for long lead-lengths or noise reduction).
Soft Start Bypass
W
UL Type 1
UL Type 3R
Provides a solid-state adjustable soft starter for use when switching to bypass mode. Option (W) provides a solid-state soft-starter with adjustable ramp to reduce mechanical system stress typically associated with across-the-line bypass motor starts. Select option (W) if the application cannot tolerate the mechanical load stress caused by across-the-line bypass motor starts.
Surge Suppressor
2
UL Type 3R This option provides a degree of protection from ansient surges coming through the power line cables. Lightning strikes are the most common source of surges.
Space Heater
3
UL Type 3R This option helps reduce condensation.
