Hammond STDA1 GE Spectra-Flex Cable Operator, 150 to 600 A

STDA1 is the General Electric reference listed for Spectra-Flex circuit breaker cable operators rated 150 to 600 A, as it appears in the selection table for Hammond's Flange Disconnect Operator Adaptor Kits. The table lists it under Operator Make & Type "General Electric - operating handle" as the manufacturer part number for the Spectra-Flex circuit breaker cable operator entry (150 to 600 A). It is aimed at panel builders and electricians matching a flange mounted operating mechanism to a Hammond disconnect enclosure.

Hammond's Flange Disconnect Operator Adaptor Kits are used to adapt flange mounted operating mechanisms to all Hammond enclosures with universal cutouts. The kits include an adaptor plate and all of the required parts, with instructions, to interlock the main door with the operator mechanism.

Related references in the same part of the table are STDA3 (Spectra-Flex, SK1200 A). The General Electric section of the table covers operating handles and Spectra-Flex cable operators. The same General Electric section of the table also lists STDA1 (or STDA2) against both the disconnect switch and the circuit breaker operating handle entries. Use the STDA1 reference to confirm which operator make and type an enclosure is being set up for before selecting the matching adaptor kit.

The manufacturer data does not publish a shipping weight, UPC, material or finish for STDA1; the facts on this page come from the series selection table. For Hammond universal type disconnect enclosures that will not carry an operator, the series also offers blank plates to cover the flange cutouts.
