The 10 mA rating makes it suitable for circuits where higher sensitivity to leakage is required — wet areas, medical locations, or equipment needing enhanced shock protection. Installation depth 70 mm. Touch protection is built in. ## Derating and ambient conditions Rated current derates with ambient temperature: 16 A at 30 °C, 15.04 A at 40 °C, 14.56 A at 45 °C, 13.92 A at 50 °C, 12.96 A at 55 °C. The 10 mA residual trip is fixed — no adjustable delay. Designed to EN 60898 and IEC 60947-2. The product designation per IEC 81346-2 is F. Energy limitation class 3. The brand provides standard compliance documentation (CE, RoHS, REACH) with the product; UL/CSA listing is not stated in the evidence for this specific variant.","metaTitle":"Siemens 5SU9156-7KK16 SENTRON RCBO, 16A 10mA Type A Curve C","metaDescription":"Siemens SENTRON 5SU9156-7KK16 RCBO, 16A rated, 10mA residual, Type A, curve C. 6kA/10kA breaking capacity. 2-pole, 2MW.
