At 55 °C it derates to 194 A, at 60 °C to 188 A, at 65 °C to 182 A, and at the 70 °C operating maximum to 176 A. ## Interrupting capacity across voltage bands 187 kA at 240 V is the headline number; at 415 V it's 121 kA, at 440 V it drops to 36 kA, and at 690 V it's 17 kA. ## Mechanical endurance and N-conductor protection Rated for 15,000 mechanical operations — not a high-cycle switching device, but adequate for backup protection in a distribution panel. N-conductor protection is set at 100%, meaning the neutral pole is fully rated rather than reduced-section.","metaTitle":"Siemens 3VA1220-5GF42-0CA0 SENTRON MCCB, 200 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA1220-5GF42-0CA0 molded case circuit breaker, 200 A rated at 40 °C, 4-pole, 187 kA at 240 V.
