Four-pole, with the neutral unprotected (no integral neutral release). The TM240 trip unit gives you thermal-magnetic overload protection adjustable from 140 A to 200 A, and short-circuit pickup adjustable 5 to 10 times In (so 1000 A to 2000 A at the 200 A setting). The suffix ZD00 flags a nut keeper kit and a DC Power OEM build origin in China — same Siemens 3VA platform, just a specific factory configuration. The 200 A frame with a TM240 trip means it's a line-protection breaker, not a motor-protective device (no electronic overload curve). The adjustable Ir (140–200 A) lets you match it to a downstream transformer or bus rating without swapping the breaker body. The Ii range of 5–10 x In gives you selectivity headroom against downstream branch breakers — set it at 10x (2000 A) if you need to coordinate with 50 A or 63 A feeders. The unprotected neutral means you need a separate neutral disconnect or a 4-pole breaker with a neutral release if the system requires neutral isolation.","metaTitle":"Siemens 3VA1220-6EF42-0AA0-ZD00 Circuit Breaker, 70 kA @ 415","metaDescription":"Siemens 3VA1220-6EF42-0AA0-ZD00 IEC frame 250, class H, 70 kA @ 415 V, 4-pole, TM240, In=200 A.
