BQD335 - 35Amp Circuit Breaker

BQD335 - 35Amp Circuit Breaker

The Siemens BQD335 is a 35-amp, 3-pole circuit breaker designed for use in 480/277VAC three-phase electrical systems. It's commonly found in commercial and industrial panelboards protecting equipment such as HVAC units, lighting circuits, pumps, and motor loads. When current levels exceed safe operating limits, the breaker is designed to trip and disconnect power, helping you prevent damage to wiring and connected equipment.

This model uses a thermal magnetic trip mechanism, providing protection against both overload conditions and short circuits. The panelboard-mount design and low-tab connections make it a practical option for replacement projects, maintenance work, and new installations where a BQD-series breaker is required.

You'll typically see breakers like the BQD335 installed in schools, office buildings, retail centers, warehouses, healthcare facilities, and manufacturing operations.
