The Siemens 3VA2220-7MQ32-0CK0 is a 3VA2 IEC Frame 250 circuit breaker with switching capacity class C, delivering an Icu of 110 kA at 415 V. It's a 3-pole unit built for motor protection, fitted with the ETU860M trip unit offering LSIG protection (long-time, short-time, instantaneous, ground fault). The continuous current rating In is 200 A, with an adjustable overload protection range Ir = 80 A to 200 A, and short-circuit protection settings Isd = 1.2 to 15 times In and Ii = 3 to 15 times In. Ground fault protection can be switched off, with adjustable Ig = 0.2 to 1 times In and time delay tg = 0.05 to 0.8 seconds. The breaker includes a lug terminal connection, an undervoltage release rated for 120-127 V AC 50/60 Hz, one auxiliary switch HQ, one tripped signaling contact HQ, and one protective tripping signaling switch.
The ETU860M electronic trip unit gives you LSIG protection — that's adjustable long-time (overload), short-time (short-circuit with delay), instantaneous, and ground fault — so you can coordinate selectivity downstream and still protect the motor branch.
