That derating curve is typical for MCCBs, but it means the same breaker cannot be applied at full fault rating across all system voltages — the 690 V figure governs if the line-neutral voltage exceeds 500 V. The 70 mm depth and 76.2 mm width fit standard MCCB panel cutouts; the 130 mm height is within the compact SENTRON 3VA frame envelope. Above that, derating is gradual: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. Maximum power dissipation is 19.2 W, which contributes to enclosure heating and should be summed across all devices in the same cabinet. The storage limit is wider because the breaker is not carrying current or under mechanical stress while stored — that range governs warehousing and shipping, not running conditions. The 76.2 mm (3-inch) width is a standard MCCB footprint for 3-pole frames in the 80 A class — fits existing panel cutouts and busbar spacing without rework.","metaTitle":"Siemens SENTRON 3VA1180-3EF36-0HA0 MCCB, 80A, 75.6kA at 240V","metaDescription":"Siemens SENTRON 3VA1180-3EF36-0HA0 molded case circuit breaker, 3-pole, 80A rated at 40°C, 75.6kA breaking capacity at 240V AC.
