The In is fixed at 40 A with overload protection Ir also fixed at 40 A, and short-circuit protection set to Ii = 10 x In (400 A). This unit includes N-conductor protection at 100% and a nut keeper kit, and is designated for a DC Power OEM in China. The FTFM (Fixed Thermal, Fixed Magnetic) trip means no field adjustment of the overload or short-circuit thresholds — what you order is what protects the circuit. ## Deployment context The 4-pole configuration suits three-phase plus neutral distribution in a 400 V industrial panel, typical for feeding a sub-distribution board or a dedicated machine supply. The fixed trip settings mean it's a designated branch circuit protector, not a general-purpose adjustable breaker — specify it where the load is known and stable. The fixed Ir and Ii settings make this a drop-in replacement for any 40 A TM210-specified 3VA1 slot; no recalculation of trip coordination is needed if the existing circuit was designed for those values.","metaTitle":"Siemens 3VA1140-4GD42-0AA0-ZD00 Circuit Breaker, 40A, 36kA @","metaDescription":"Siemens 3VA1140-4GD42-0AA0-ZD00 IEC frame 160 circuit breaker, 40A, 36kA breaking capacity at 415V.
