Its interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V, tapering to 30 kA at 500 V and 4.5 kA at 690 V — giving it strong selectivity headroom in low-voltage switchgear, especially at the 415 V common in industrial distribution. Derating begins at 55 °C (194 A), dropping to 176 A at 70 °C. This matters when the breaker is enclosed in a crowded panel with limited airflow — the 70 °C curve applies in a typical NEMA 12 enclosure with multiple devices. Physical footprint: 105 mm wide, 158 mm high, 70 mm deep. ## Auxiliary switch configuration and trip indication The trip alarm signals a fault condition separate from manual open/close — useful for remote annunciation in a PLC-driven system.","metaTitle":"Siemens SENTRON 3VA1220-5MH32-0AJ0 MCCB, 200 A, 3-Pole, TM12","metaDescription":"Siemens SENTRON 3VA1220-5MH32-0AJ0 molded case circuit breaker, 200 A, 3-pole, TM120M release, 187 kA at 240 V.
