What happens when the transfer switch shows up on site — and it's the wrong voltage? The job stops. Crews wait. Costs climb by tens of thousands a day, and the relationship with your customer takes the hit.
The new ASCO 300 SERIES MAulti-Voltage Power Transfer Switch is built to make that problem disappear. One field-configurable switch covers 208V through 480V, so a simple on-site adjustment — no energizing, no specialized service call — sets the unit to whatever the application demands. Last-minute change order from 208V to 480V? Reconfigure in place and keep the project on schedule.
For distributors and contractors, it also collapses ordering complexity: stock one model instead of ten-plus voltage-specific variants, reducing SKU complexity by up to 90% while improving availability. Built on the proven Series 300 platform — over 2 million switches deployed and 100+ years of power-switching expertise — it pairs flexibility with reliability you already trust.
Join us to see how one switch eliminates voltage-mismatch delays, simplifies stocking, and gets the right power where it's needed — fast.
- Recognize the real cost of voltage mismatch — how voltage-specific ordering creates delays, downtime, and customer friction on active projects.
- Understand how field-configurable voltage works — the simple on-site process for setting any voltage from 208V to 480V without energizing the unit or calling for service.
- Apply the switch to real-world scenarios — including last-minute change orders and reconfiguration of already-installed units to keep projects on schedule.
- Quantify the ordering and inventory advantage — how a single multi-voltage model replaces ten-plus variants, simplifies forecasting, and improves availability.
