The Siemens 3VA1220-6EF32-0JA0 is a 3-pole IEC molded-case circuit breaker in the 3VA1 platform, rated In=200A with a TM240 thermal-magnetic trip unit. The ATAM designation means the overload setting is adjustable (Ir=140A...200A), and the short-circuit pickup Ii is adjustable from 5 to 10 times In — giving you 1000A to 2000A magnetic trip. That adjustability lets you fine-tune coordination with downstream feeders without swapping the breaker body. Breaking capacity class H delivers Icu=70kA at 415V AC. This is the ultimate short-circuit capacity the breaker can interrupt without damage. For a 200A frame, 70kA at 415V is high — it suits strong utility feeds or transformer secondaries where fault current can exceed 50kA. The H class means it's rated for the higher end of industrial distribution, not light commercial. The built-in shunt trip (STL) operates on 110-127V DC or AC 50/60Hz. That's a standard control voltage for many industrial panels — you can trigger remote trip from an E-stop or a PLC output without an interposing relay.
We source the 3VA1220-6EF32-0JA0 to order against an RFQ. For volume requirements or scheduled releases, we can provide a multi-unit quote with lead time.
