It also includes 100% neutral conductor protection and a nut keeper kit, built for a DC Power OEM application in China. The TM240 trip unit gives you thermal-magnetic protection: the thermal element handles overloads (Ir adjustable 280–400 A), and the magnetic element handles short-circuits (Ii adjustable 5–10× In). For a 400 A feeder, that Ii range is 2,000 to 4,000 A — typical for protecting cable runs or downstream distribution, not a motor starter directly. This breaker belongs in a main or branch feeder position in an IEC-rated switchboard or panel. The 4-pole configuration with 100% neutral protection makes it suitable for TN-S or TN-C-S systems where the neutral is treated as a live conductor and needs overcurrent protection. The nut keeper kit and OEM designation suggest it was ordered as part of a larger assembly for a DC Power equipment builder in China — likely a rectifier or UPS input feeder.","metaTitle":"Siemens 3VA1340-6GF42-0AA0-ZD00 Circuit Breaker, 70kA @ 415V","metaDescription":"Siemens 3VA1340-6GF42-0AA0-ZD00 IEC frame 400 breaker, 70kA Icu @ 415V, 4-pole, TM240 ATAM, In=400A.
