Rated current holds flat at 32 A from 40 °C through 50 °C, then derates to 30 A at 70 °C. That thermal stability means the breaker doesn't lose headroom in a warm panel unless ambient pushes past 55 °C. The 75.6 kA interrupting rating at 240 V gives ample SCCR headroom for most North American distribution transformers; at 415 V it still clears 52.5 kA, and at 690 V it holds 11.9 kA. ## Approvals and compliance documentation Rated insulation voltage is 800 V, and the breaker carries a -25 °C to 70 °C operating range with -40 °C to 80 °C storage limits. The SENTRON series holds UL, CSA, and IEC certifications standard for panelboard and distribution applications. Compliance documentation (RoHS, REACH, UL file, IEC test reports) is available through the manufacturer's documentation portal — the breaker itself carries the CE and UKCA marks for European and UK markets.","metaTitle":"Siemens 3VA1132-3EF36-0CH0 SENTRON MCCB, 32 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1132-3EF36-0CH0 molded case circuit breaker, 32 A rated at 40 °C, 3-pole, 75.6 kA breaking at 240 V.
