Those are the maximum fault currents it can safely clear at each voltage level. For a 480 V panel with a 65 kA available fault current, the 76 kA at 440 V rating gives you comfortable headroom — no need to cascade upstream. The 30 kA at 500 V covers the high-end industrial bus. The 690 V insulation voltage (Ui) means the internal creepage and clearance are built for 600 V class systems. The 3VM1220-5GD42-0AA0 measures 70 mm deep, 140 mm wide, and 158 mm tall. Front protection is IP40, so it's sealed against tools and fingers but not washdown. No motor drive option, no communication module; it's a straightforward thermal-magnetic breaker for hardwired distribution.","metaTitle":"Siemens 3VM1220-5GD42-0AA0 SENTRON MCCB, 200 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VM1220-5GD42-0AA0 molded case circuit breaker, 200 A continuous, 4-pole, TM210 release.
