The Siemens 3VA1220-5EF42-0AH0 is a SENTRON molded case circuit breaker (MCCB) rated for 200 A continuous current at 40 °C, holding that full rating through 50 °C before the thermal curve starts to bite — at 55 °C it's 194 A, at 70 °C it's 176 A. That flat-top derating profile means you don't lose headroom in a warm panel until the ambient actually pushes past 50 °C. The 4-pole design and TM240 thermal-magnetic release make this a line-protection breaker, not a motor-protection device — the TM240 release is sized for cable and busbar protection, not for an overload relay curve. If your safety circuit or PLC needs a separate signal that the breaker tripped on fault (not just that it's open), that alarm contact is the one to wire. No washdown rating here; this lives inside the enclosure.
The breaker footprint is 140 mm wide by 158 mm tall by 70 mm deep — that's a 4-pole MCCB in the SENTRON 3VA frame size. Verify the busbar system (pin or fork type) matches the line-side connection pattern for your distribution board.
