Eaton C320AS1 – Frequently Asked Questions

1) What does the Eaton C320AS1 transient suppressor do in a motor starter circuit?
The C320AS1 is a transient suppressor for Eaton NEMA Freedom starters and contactors. It wires across the contactor coil, so it deals with the voltage transient generated when the coil de-energizes, right at the source. That matters when the same control circuit feeds PLC inputs or other solid-state devices that are sensitive to coil kickback.
2) How does the C320AS1 suppressor mount on an Eaton Freedom starter?
It mounts on top of any side-mounted auxiliary contact on the starter or contactor, then lands across the coil. No separate bracket or panel space is needed, which is the point of the design: you give up the top of an aux contact position rather than DIN rail real estate.
3) Do I need a side-mounted auxiliary contact already installed to use this suppressor?
Yes. The C320AS1 mounts on top of a side-mounted auxiliary contact, so that auxiliary contact has to be on the starter or contactor first. If the unit has no side aux contact fitted, order one along with the suppressor.
4) Will this Eaton suppressor work on another brand of contactor?
No. The C320AS1 is a NEMA Freedom accessory, dimensioned and keyed for Eaton Freedom starters and contactors and their side-mounted auxiliary contacts. For a different manufacturer's contactor, use that manufacturer's own coil surge suppressor module.
5) Will the Eaton C320AS1 fit in my existing enclosure without adding depth?
Footprint is 1.2 in wide by 1.9 in long/deep by 2.3 in high. Because it stacks on top of an aux contact rather than beside the contactor, the number to watch is the 2.3 in height above the aux contact position, not the panel width.
6) Is the Eaton NEMA Freedom transient suppressor UL Listed?
Yes, the C320AS1 is UL Listed, which is what a plan reviewer or facility inspector will look for on an accessory added inside a motor control panel.
7) Can I add the C320AS1 to starters that are already installed and running?
Yes, it is built for retrofit as well as new builds. Since it clips onto an existing side-mounted auxiliary contact and ties across the coil, adding coil suppression to an in-service Eaton Freedom starter does not mean rebuilding the assembly. Work de-energized.
8) How many suppressors do I need for a panel full of starters?
One per coil. The C320AS1 connects across a single contactor coil, so a panel with six Freedom starters that all need suppression takes six units, each on its own side-mounted aux contact.
