The 32 A rating at 30 °C derates to 24.64 A at 70 °C — that thermal curve is the real-world ampacity you need for the panel ambient, not the label number. The higher IEC figure applies when the device is used as a distribution breaker in industrial panels; the EN figure governs domestic/commercial final circuits. The super resistant K designation means the housing and internal materials are formulated for higher chemical resistance and thermal stability — relevant in aggressive environments like wastewater treatment, chemical processing, or outdoor enclosures where standard RCBOs may degrade. The IP20 rating is typical for enclosed distribution boards; the device is not intended for wet or dust-laden exposure without an outer cabinet. Snap-on mounting for DIN rail EN 60715, any position. Halogen-free and silicon-free construction — important for panels in high-reliability or corrosive environments where outgassing from a fault could damage adjacent electronics or cause contact corrosion.","metaTitle":"Siemens 5SU1354-4KK32 SENTRON RCBO, 32 A C-curve, 10 kA","metaDescription":"Siemens 5SU1354-4KK32 SENTRON RCBO, 1P+N, 32 A C-curve, 10 kA per EN 60898, 15 kA per IEC 60947-2.

The 5SU1354-4KK32 is a 2-MW (36 mm) RCBO with 32 A C-curve, while the 5SL series are standard MCBs. Check the panel cutout width and the required protection function (RCBO vs MCB) before substituting."},{"question":"Where can I buy 5SU1354-4KK32 and how is it quoted?","answer":"Sourced and quoted to order against an RFQ through independent distribution.
