“Find LS Electric Metasol 50 amp reversing contactor assembly part numbers and 120 VAC coil mechanical interlock compatible with MC-50a at 460 V”
18 catalog listings from 15 independent supplier and documentation sites, covering the assembled reversing catalog number, nine 120 VAC MC-50A contactor variants, the UR-02 interlock and the UW-63 reversing wire kit. The MC-50A is rated 50 A AC-3 and 40 HP at 440–480 V three phase, so it covers 460 V; 120 VAC is only the control-coil voltage.
No numeric LS order number for the pre-assembled MC-50A/R-AC120V was found on any of the 15 hosts — confirm with the distributor whether it ships factory-assembled or as a field kit. doczz.net
The three numeric contactor order numbers are not interchangeable: 1338012900 is screw-terminal 2NO+2NC, 1380012900 is lug-terminal 2NO+2NC, and 1380001300 is lug-terminal with no stated auxiliaries. valinonline.com
UR-02 (MPN 83411634001) is a mechanical/electrical interlock with 2 NC contacts, compatible across Metasol MC-9B through MC-150A — explicitly including MC-50a — and is not voltage-specific. voomisupply.com
UW-63 (MPN 76671632003) is the separate power reversing wire kit for MC-50a/65a — do not confuse it with UR-02; a field-built reverser needs both. wolfautomation.com
D0004327 appears only in a regional South African price list as a code for UR-02; 83411634001 is the North American-style LS number seen from two sellers. electechls.co.za
