It's a 4-pole unit with a TM240 thermal-magnetic trip set at In=40A. Overload protection is adjustable Ir=28A...40A, and the short-circuit pickup Ii is fixed at 5...10 x In. The N-conductor protection is 100% rated, so the neutral pole carries the same trip curve as the phases — that matters for 4-wire systems where unbalanced loads or harmonics can push neutral current to phase levels. The suffix ZD00 indicates a nut keeper kit and DC Power OEM configuration for the China market. The nut keeper secures the breaker to the busbar assembly during high-vibration transport or operation; the DC Power variant tailors the trip curve for battery-bank or rectifier-fed circuits where the DC component affects magnetic pickup timing. Because it's a current-production item with a custom OEM variant code (ZD00 suffix), availability runs through the standard Siemens distribution channel. Frame 160 means it mounts on a standard 160A-rated busbar system with 4-pole spacing. The nut keeper kit (included) locks the breaker onto the busbar studs — no separate lock-washer or torque-marking step needed for the OEM line. The TM240 trip unit is non-interchangeable (fixed thermal-magnetic), so the overload and short-circuit settings are the only adjustable parameters. If you need a higher continuous current or a different trip curve later, you swap the whole breaker — not just the trip unit. N-conductor protection at 100% means the neutral pole's thermal element sees the same Ir range as the phases. In a 3-phase + N distribution board, that avoids nuisance tripping on neutral-heavy loads like VFD input filters or LED lighting banks.","metaTitle":"Siemens 3VA1140-6GF42-0AA0-ZD00 IEC Frame 160 MCCB, 70kA @ 4","metaDescription":"Siemens 3VA1140-6GF42-0AA0-ZD00 circuit breaker, IEC frame 160, 70kA breaking capacity @ 415V, 4-pole, TM240 thermal-magnetic trip 40A.
