What this 80 A MCCB delivers
Its interrupting capacity reaches 121 kA at 240 V and 75.6 kA at 415 V, which means it can safely clear high-fault currents on the secondary side of a step-down transformer or a 400 V bus without cascading upstream — a key selectivity consideration for site electrical engineers. 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.
