3VA6140-5HN41-2AA0 SIEMENS

The 3VA6140-5HN41-2AA0 is a robust and reliable molded case circuit breaker (MCCB) from Siemens' 3VA6 series, designed for UL-standard applications. This 4-pole circuit breaker provides comprehensive line protection with an Electronic Trip Unit (ETU) 350. It has a frame size of 150 and a breaking capacity class M, capable of interrupting fault currents up to 35kA at 480V. The ETU350 offers adjustable Long-time (L), Short-time (S), and Instantaneous (I) protection functions. The rated current (In) is 40A, with an adjustable overload protection range (Ir) from 16A to 40A. The short-circuit protection (Isd) can be set from 1.5 to 10 times the Ir value, while the instantaneous protection (Ii) is fixed at 12 times the In value. This MCCB also features adjustable neutral conductor protection, which can be set to OFF or 100% of the phase current, without requiring a direct connection. This allows for flexible adaptation to various system configurations and protection requirements. The 3VA6140-5HN41-2AA0 ensures reliable and efficient protection for electrical systems, minimizing downtime and enhancing safety.
