Replaces / Drop-In Replacement For
The Z93S2456MO1A3 is a discontinued model; Aerovox ceased operations in 2018 following bankruptcy. While replacement stock remains available through specialty distributors, form-fit-function alternatives are recommended for new installations. Verify compatibility with your system integrator before ordering, as voltage and capacitance ratings must match original equipment specifications exactly.
Works With
- Standard 50/60 Hz AC power systems
- Screw and lug terminal connection blocks
- Ballast controller circuits rated for oval film capacitor mounting
- Industrial relay and contactor-based motor starters
- Power quality monitoring and correction systems requiring capacitive compensation
