For a panel running at 55 °C, expect 313 A continuous capability — useful when sizing for elevated enclosure temperatures. The breaker measures 248 mm high, 184 mm wide, and 110 mm deep. The 184 mm width across four poles is the key panel-space constraint — verify the mounting footprint against your existing busbar or DIN-rail layout before committing the BOM line. Front face carries an IP40 protection class, suitable for general indoor panel environments where tools or fingers are the main contact risk. No IP rating is stated for the rear or sides — the breaker relies on the enclosure for overall ingress protection.","metaTitle":"Siemens 3VA1332-4GE42-0AA0 SENTRON MCCB, 320 A, 4-Pole, TM22","metaDescription":"Siemens 3VA1332-4GE42-0AA0 SENTRON molded case circuit breaker, 320 A, 4-pole, TM220 release, 121 kA at 240 V.
