Breaking capacity is the headline number here: 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V. Those are high-interrupt ratings — this breaker can clear a serious fault without welding its contacts shut or venting plasma into the enclosure. At 690 V it still manages 17 kA. The 3VA1180-5EF32-0BA0 measures 70 mm deep by 76.2 mm wide by 130 mm tall.","metaTitle":"Siemens SENTRON 3VA1180-5EF32-0BA0 MCCB, 80 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1180-5EF32-0BA0 molded case circuit breaker, 80 A rated continuous current, 187 kA breaking at 240 V. 3-pole line protection with undervoltage release.
