A precision replacement reversing moving contact for McGraw-Edison 550B load tap changers (LTCs), machined to OEM dimensional specifications. Material certification available on request.
The McGraw-Edison 550B Reversing Moving Complete replaces the reversing moving contact in for McGraw-Edison 550B load tap changers (LTCs). Southern Switch & Contacts machines it to OEM dimensional specifications from the correct contact alloy, with material certification available on request.
Worn or burned tap-changer contacts raise resistance, run hot, and can lead to tap-changer failure. Precision replacements restore reliable switching and extend the service life of the LTC.
Common items are produced on short lead times; discontinued or hard-to-find parts are reverse-engineered from a sample, a drawing, or a model number. Based in Palm Harbor, FL, Southern Switch & Contacts manufactures and ships replacement parts to utilities nationwide, and has served the industry since 1982.
