The 70 mm depth and 101.6 mm width fit standard MCCB panel cutouts; the IP40 front rating means it is protected against solid objects larger than 1 mm but not sealed against moisture — suitable for indoor switchboards, not washdown environments. No official successor has been announced for this order code. For a BOM line that requires this exact 80 A, 4-pole TM220 configuration, the 3VA1116-4FE42-0AA0 remains the direct fit. ## Installation constraints Verify your control scheme does not rely on shunt-trip or remote signaling before specifying. Maximum power loss is 38 W; ensure adequate ventilation in the panel to keep internal ambient below 70 °C operating limit.","metaTitle":"Siemens 3VA1116-4FE42-0AA0 SENTRON MCCB, 80 A, 4-Pole, 121 k","metaDescription":"Siemens 3VA1116-4FE42-0AA0 SENTRON molded case circuit breaker, 80 A rated, 4-pole, interrupting 121 kA at 240 V.
