Four poles, with 100% neutral protection designed in. The TM210 thermal-magnetic release handles overload and short-circuit trip curves. Interrupting capacity hits 220 kA at 240 V AC and 154 kA at 415 V, dropping to 17 kA at 500 V and 690 V. ## What the interrupting ratings mean for panel coordination The 220 kA at 240 V is the headline number, but the real-world selectivity decision lives at 415 V (154 kA) and 440 V (121 kA).","metaTitle":"Siemens 3VA1140-6GD42-0AA0 SENTRON MCCB, 40 A, 4-Pole, 220 k","metaDescription":"Siemens SENTRON 3VA1140-6GD42-0AA0 molded case circuit breaker, 40 A, 4-pole, TM210 release, 220 kA at 240 V.
