Q4L3400

The Q4L3400, part of Schneider Electric's Q4 Series, is a high-capacity circuit breaker designed to handle significant electrical loads. Operating at 240 VAC and configured for 3-phase systems, it provides a robust solution for applications requiring a rated current of 400 A. With an interrupt rating of 25 kA, this breaker ensures protection against overcurrents, contributing to the safety and reliability of electrical systems.

This circuit breaker employs a thermal magnetic mechanism, allowing it to respond to both long-term loads and instantaneous surges. The configuration features three poles and supports feed-thru connections, enhancing its adaptability in a variety of setups. Weighing 7.43 pounds, the device is manageable for installation in diverse settings.

Environmental resilience is a notable aspect of the Q4L3400. It operates efficiently within a temperature range from 0°C to 40°C, making it suitable for moderate climates. Additionally, it can tolerate relative humidity levels of up to 80% (non-condensing). Furthermore, this unit is rated for operation at altitudes reaching 1000 meters above sea level. Its design effectively accommodates the typical conditions found in many industrial and commercial environments.
