About the Moloney MA1/MB1 Load Tap Changer
The Moloney MA1 and MB1 are updated variants of the MA/MB load tap changer with a revised collector ring and contact geometry. Like the MA/MB, they use a transfer switch, selector switch, and reversing switch arrangement. The transfer switch stationary contacts, collector ring assembly, and selector switch moving contact are the scheduled maintenance items. Southern Switch machines replacement contacts and complete kits for the MA1 and MB1.
Why replace worn LTC contacts
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.
