The Schneider Electric LV431756 is a fixed circuit breaker designed for superior performance in electrical applications. This model is engineered for front connection and fixed mounting, allowing for straightforward installation in various setups. Its instantaneous setting range can be adjusted between 9 and 14 times the nominal current, offering flexibility tailored to specific operational demands.
This circuit breaker withstands high insulation voltage rated to 800 V AC while also handling impulse withstand peaks up to 8 kV. The unit supports an ultimate breaking capacity of 70 kA for voltages between 380 and 415 V AC, making it suitable for environments with significant fault currents.
Constructed with three poles for three-phase configurations, the LV431756 operates efficiently at a rated current of 220 A when running at temperatures of 65 °C. The maximum operating voltage is up to 690 V AC at either 50 or 60 Hz. Its electrical characteristics place it in Utilization Category A, which indicates it does not provide short-time or ground fault protection.
With a lifespan of 20,000 mechanical operating cycles and 5,000 electrical cycles at its rated load, the circuit breaker demonstrates excellent durability. Furthermore, the connection pitch measures 35 mm, and it features an IP40 rating for dust protection, indicating reliability in environments where dust exposure is minimal yet functionality remains critical.
