The DC maximum operating voltage is 72 V — relevant if the circuit includes a rectified supply or battery-backed control voltage. For purely resistive loads or long cable runs, a B-curve would trip faster; for high-inrush transformers, a D-curve would be the usual choice. ## Panel fit and environmental tolerance Installation depth is 70 mm. Mounting position is any. The operating temperature range spans -40 °C to 75 °C, with humidity derating: up to 95% relative humidity at 55 °C, tapering to 35% at 75 °C. Vibration resistance per IEC 60068-2-6 is ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz, adequate for general industrial machinery but not for direct mounting on a high-vibration pump skid without isolation. Compliance documentation per IEC/EN 60947-2 is the governing standard. The part is sealable — a feature for utility-metering or warranty-seal applications where tamper evidence is required.","metaTitle":"Siemens 5SY4202-7CV MCB, 2P C2, 15kA IEC/EN 60947-2","metaDescription":"Siemens 5SY4202-7CV miniature circuit breaker, 2-pole, C-curve, 2A, 15kA breaking capacity at 400V AC per IEC/EN 60947-2.
