Circuit Breaker Accessories
Shop breaker trip units, rating plugs, shunt trips, auxiliary switches, undervoltage releases, closing coils, lugs, handles, mounting hardware, and related circuit-breaker accessories.
Accessories are frame- and series-specific. Send the breaker catalog number, frame, trip-unit label, control voltage, accessory function, and clear photos so Ampstate can verify compatibility before quoting.
Email sales@ampstate.com for technical matching and availability.
