It carries a TM120M thermal-magnetic trip unit, set for starter protection. The In=200A rating is the continuous current; the short-circuit protection pickup Ii is adjustable from 6 to 14 times In (1200 A to 2800 A). Note the description states 'without overload protection' — the TM120M here is configured for magnetic-only short-circuit protection, so the overload function is not active. This is typical for motor starter combination applications where a separate overload relay handles the thermal protection. ## Included accessories and wiring note The HQ switches provide early-break / late-make contact sequencing for signaling the breaker's open/closed/tripped state to a PLC or safety circuit. When wiring the auxiliaries, verify the contact ratings against your control voltage — the HQ designation follows Siemens' standard auxiliary contact block specification.","metaTitle":"Siemens 3VA1220-6MH32-0AD0 Circuit Breaker, 70kA @ 415V","metaDescription":"Siemens 3VA1220-6MH32-0AD0 IEC frame 250 circuit breaker, breaking capacity class H, Icu=70kA @ 415V. 3-pole, starter protection TM120M, In=200A.
