It is a line-protection device — meaning it guards cables and distribution feeders against overload and short-circuit, not motor or generator protection. ## Breaking capacity — the real-world fault rating This MCCB's interrupting capacity varies sharply with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. ## Thermal derating — the number that matters in a hot panel At 55 °C it drops to 38.4 A, at 60 °C to 37.6 A, at 65 °C to 36.8 A, and at 70 °C to 36 A. The 76.2 mm width is a standard 3-pole MCCB footprint — it fits the same panel cutout as most 3VA 3-pole breakers. The shunt trip accessory (order code 3VA9688-0BL30) is a separate add-on; it does not ship with the breaker. No auxiliary contacts are included, so if you need status feedback to a PLC, you'll need to order those separately. The breaker has no trip indicator, no phase-failure detection, and no communication function — it's a straightforward thermal-magnetic protector with remote trip capability via the shunt release.","metaTitle":"Siemens 3VA1040-3ED36-0HA0 SENTRON MCCB, 40 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1040-3ED36-0HA0 molded case circuit breaker, 40 A rated, 3-pole, breaking capacity 75.6 kA at 240 V.
