• Integrated 35A rating: Tailored for feeder and branch circuits that require reliable yet precise current protection.
• 480 V electrical systems: Ready for common industrial power rails and distribution panels, simplifying replacement and upgrades.
• Built-in potential transformer: Provides voltage sensing for protection relays and metering without extra transformers or complex wiring—streamlining installation and improving fault detection accuracy.
• Part number 994335: A direct replacement and compatible fit with Square D panels and associated protection schemes.

What problems it solves

The combination of a circuit breaker with an integrated potential transformer minimizes cabling, reduces installation time, and supports accurate voltage monitoring. It helps ensure protection coordination across all phases and makes it easier to feed protection relays and metering devices from a single device.

Ideal use cases

• Industrial manufacturing lines and heavy machinery powered by 480 V three-phase systems.
• Commercial equipment rooms and data centers requiring reliable feeder protection with integral sensing capability.
• Panel upgrades or retrofits where space, wiring, and integration complexity matter.

Installation and compatibility tips

Before installation, verify that your distribution panel accepts Square D devices in this form factor and that the 3-Pole 480 V rating aligns with your system. Confirm that the 35 A current rating matches the feeder or circuit you intend to protect, and plan for wiring that accommodates the integrated potential transformer for signal outputs to your protection relays or metering equipment. Follow all safety guidelines and consult a licensed electrician if in doubt.

Upgrade your protection strategy with the Square D 994335—where robust three-phase protection meets streamlined voltage sensing, all in a single, dependable device.
