Schneider Electric QDM32110TN 110A 3-Pole 240 V Circuit Breaker Potential Transformer

Meet the Schneider Electric QDM32110TN, a purpose-built circuit breaker with an integrated potential transformer designed to deliver reliable protection and precise metering in 3‑phase power systems. With a 110 A current rating, a 3-pole configuration, and a 240 V nominal voltage, this device is tailored for demanding industrial and commercial environments where accurate monitoring and dependable fault isolation matter.

Why this combination matters

By pairing a high-quality circuit breaker with an integrated potential transformer, the QDM32110TN provides a clean, single‑point solution for both protection and measurement. The included potential transformer supplies a scaled voltage signal to metering equipment and protective relays, simplifying wiring, reducing installation time, and improving the reliability of monitoring and fault‑detection systems.

Key advantages

• 110 A current rating— suitable for protecting moderate to substantial feeders without excessive nuisance tripping.
• 3-pole design— ideal for three-phase distributions, ensuring balanced protection across phases.
• 240 V voltage rating— compatible with common commercial and industrial power networks.
• Integrated potential transformer— delivers a measurement-ready signal for meters and relays, reducing additional components and cabling.
• Part Number QDM32110TN— straightforward ordering and replacement within Schneider Electric’s ecosystem.

Ideal use cases

• Feeder protection in industrial control panels and distribution boards where space or wiring complexity is a constraint.
• Power monitoring and relay coordination in data centers, manufacturing lines, and large office complexes.
• Retrofits or upgrades of legacy switchgear that benefit from integrated metering signals to modern protection schemes.

What sets it apart

Unlike standalone protection devices, the QDM32110TN streamlines installation by combining circuit protection with a calibrated voltage output for metering and protection relays. This integration reduces wiring, lowers installation costs, and enhances reliability by minimizing connections that can drift or corrode over time. It’s a practical solution for engineers seeking precise measurement without sacrificing robust circuit protection.
