The 40 A fixed thermal-magnetic trip (TM210, FTFM) provides line protection with overload Ir fixed at 40 A and short-circuit pickup Ii set at 10 x In (400 A). The N conductor is protected at 100%, which matters for four-wire systems where the neutral carries phase imbalance current. This specific variant includes a nut keeper kit and is configured for DC Power OEM use in China, so the mounting hardware and terminal arrangement are set for that production line. ## Deployment context — panel integration and field fit At 4-pole width on a 160 A frame, it occupies four modular units of DIN space — plan your gland plate and wireway clearance accordingly. The nut keeper kit simplifies torque-down on the line and load lugs; it's a small detail that saves time on a repetitive assembly line. For field-service swaps, the fixed thermal-magnetic trip means no adjustment dials to verify — set it and forget it, which is exactly what you want when the spare comes out of the van and needs to match the existing installation.","metaTitle":"Siemens 3VA1140-6GD42-0AA0-ZD00 Circuit Breaker, 70kA @ 415V","metaDescription":"Siemens 3VA1140-6GD42-0AA0-ZD00 IEC frame 160, 4-pole, 70kA breaking capacity at 415V, 40A fixed thermal-magnetic, DC Power OEM variant.
