It is intended for line protection — not motor circuit protection — so the thermal-magnetic trip curve is calibrated for feeder and branch-circuit overcurrent, not the inrush profile of a motor start. ## Current ratings across the ambient range Above that the breaker derates: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. The maximum operating ambient is 70 °C; the minimum is -25 °C. Storage limits are -40 °C to 80 °C. ## Interrupting ratings by voltage The interrupting capacity is voltage-dependent: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. For a 480 V panel the relevant figure is the 440 V rating — 75.6 kA — which is the nearest published point above 480 V. The 3-pole width of 76.2 mm (3 inches) matches the standard 3-inch per-pole spacing for panelboard and switchgear cutouts. The basic switch assembly is order code 3VA11805EF360AA0, which is the internal switching mechanism; the complete breaker as listed here includes that assembly plus the shunt trip and auxiliary switches.","metaTitle":"Siemens 3VA1180-5EF36-0JC0 SENTRON MCCB, 80 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1180-5EF36-0JC0 molded case circuit breaker, 80 A rated at 40 °C, 3-pole, 187 kA interrupting at 240 V.
