Panel Space Savings
This proven switch technology has the fuses incorporated on the top of the switch mechanism to reduce the footprint of the product and save valuable panel space.The non-fused switch is designed to cover ratings from 30-1200 amperes in just 5 frame sizes.
Personnel Safety
Double break contacts through 400 amperes - The newest technology has designed a mechanism that disconnects both sides of the fusing using two double break contacts per pole. This insures complete isolation of the fuse in the "Off " position.
Touch safe design
All switches are designed to reduce the danger of accidental contact with live, energized parts. All fusible switches are supplied with fuse covers as standard. Fuses can be tested without removing the fuse covers. All switches are supplied with line side terminal shrouds. Optional load side terminal shrouds are available.
Clear position indication
All devices have clear indication of the "On" and "Off" ("I" & "O") positions both on the handle and on the switch.
Padlocking
All device handles can be padlocked in the "Off" position with up to three padlocks, meeting OSHA requirements for lockout/tagout procedures. On fusible devices through 400 amperes and non-fusible switches through 200 amperes, there are provisions for padlocking directly on the switch.
Door interlock defeater
Handles may be padlocked in the "Off" position. This interlocking can be defeated by authorized personnel.
Positive indication
If the contacts have welded for any reason, the operating handles cannot be moved from the "On" to the "Off" position, avoiding a false indication of contact opening.
Exceptional Short Circuit Protection
The GS1 series, when used with type CC or J fuses, provide a short circuit withstand from 50 to 200 Ka.
Test Position
An optional test position feature allows the testing of auxiliary contacts used in the control circuit. With this feature, the power circuit does not have to be energized to confirm control circuit functions.
Complete Range of Handles
The GS1 and LK3 devices use common through the door handles. Handles have both IP ratings as well as Type 1, 12 and 4/4X (indoor) ratings (as defined by UL 508). All handles are available in black or red/yellow. Optional handles are available to indicate the optional "test" position.
