It carries a continuous 63 A at 40 °C without derating — the rating holds flat through 50 °C, then drops 1 A per 5 °C step to 58 A at 70 °C, so a panel running warm at 55 °C still gets 62 A of headroom. Breaking capacity hits 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V, which covers most industrial service-entrance and panelboard fault levels in North American and IEC installations. Four poles give you the option to switch the neutral or use the fourth pole for a second load circuit — common in three-phase-plus-neutral distribution or dual-feed configurations. The 70 mm depth and 101.6 mm width fit standard MCCB panel cutouts; the 130 mm height leaves room for busbar connections above and below.
Front-face protection is IP40 — tools and fingers are kept out, but the breaker is not sealed against hose-down or dust ingress. Mount it inside a panel with a door; it is not a standalone outdoor enclosure.
Integration and fit notes
The 70 mm depth and 101.6 mm width match the standard footprint for 4-pole SENTRON 3VA1 breakers. No special adapter plate needed for most DIN-rail or panel-mount enclosures — the breaker bolts directly to the mounting base with the supplied hardware. If you need undervoltage protection or remote tripping, look at the 3VA1 with the appropriate accessory slot.
