No ground-fault monitoring or communication module on this order code; it's a straight line-protection breaker with undervoltage supervision. ## Thermal derating and power loss The 32 A rating holds steady up to 50 °C ambient; above that it derates to 31 A at 55–60 °C, and 30 A at 65–70 °C (–). That's a mild derating curve — you lose only 2 A over a 30 °C rise, which is better than many MCCBs that drop 10–15 %. Maximum power loss is 13.1 W, which matters for thermal budget in a sealed, uncooled enclosure. No trip indicator on the front, so you'll need the auxiliary switch feedback or a visual check of the handle position to confirm state.","metaTitle":"Siemens 3VA1032-3ED36-0BC0 SENTRON MCCB, 32A, 3-Pole, 75.6kA","metaDescription":"Siemens SENTRON 3VA1032-3ED36-0BC0 molded case circuit breaker, 32A rated, 3-pole, 75.6kA interrupting at 240V.
