The Siemens 3VA2220-5MN32-0JL0 is a SENTRON molded case circuit breaker (MCCB) in a motor protection configuration, carrying a 200 A rated continuous current (Iu) across a 3-pole frame. That 200 A holds steady from 40 °C up to 50 °C, then derates to 192 A at 55 °C, 188 A at 60 °C, 184 A at 65 °C, and 180 A at 70 °C — so in a warm enclosure you still have headroom for a 180 A motor full-load amp draw without nuisance tripping. Breaking capacity is the other headline: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. That 187 kA at 240 V covers high-fault utility feeds; the 121 kA at 415 V handles most European industrial distribution. The 17 kA at 690 V is lower but still adequate for most 690 V motor circuits — just verify your available fault current at that voltage against the curve. The ETU350M electronic trip unit gives you phase-failure detection and a voltage-trigger function. The auxiliary contact block is loaded: 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch. A shunt trip release (STL) is built in for remote opening. The base switch is 3VA2220-5MN32-0AA0, and the integrated auxiliary trip module is 3VA9688-0BL32.
The 3VA2220-5MN32-0JL0 measures 105 mm wide, 181 mm high, and 86 mm deep. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.
