The 70 mm depth and 140 mm width fit standard MCCB panel cutouts; the 158 mm height clears most distribution board covers. ## Interrupting Capacity Across Voltage Tiers The interrupting ratings span the common voltage levels: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. ## Auxiliary Switching and Trip Indication The trip indicator gives a visible flag when the breaker has opened on a fault. No communication function or voltage-triggered shunt trip is included — this is a straightforward thermal-magnetic breaker for hardwired distribution. Lifecycle status is current production. Standard catalog item in the SENTRON 3VA series, sourced through independent distribution.","metaTitle":"Siemens 3VA1220-5GF42-0AH0 SENTRON MCCB, 200 A, 4-Pole, 187","metaDescription":"Siemens 3VA1220-5GF42-0AH0 SENTRON molded case circuit breaker, 200 A, 4-pole, TM240 release. 187 kA at 240 V, 121 kA at 415 V.
