This MCCB's interrupting rating varies sharply with system voltage: 187 kA at 240 V AC, 121 kA at 415 V, 30 kA at 440 V, and 17 kA at 690 V. At 690 V the 17 kA rating is adequate for typical 690 V motor control centers but not for high-fault utility tie points. ## Thermal derating — don't lose capacity to heat Above that it derates: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. ## Auxiliary contacts and protection class The breaker ships with 3 auxiliary switches (HQ type) — these are factory-installed, not field-added. They provide status feedback (open/closed/tripped) to a PLC or indication lamp without external interposing relays.","metaTitle":"Siemens 3VA1216-5MH32-0AD0 SENTRON MCCB, 160 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA1216-5MH32-0AD0 molded case circuit breaker, 160 A rated continuous current, 3-pole, TM120M thermal-magnetic release, 187 kA at 240 V.
