The 10 mA trip threshold catches leakage paths that a standard 30 mA RCD would miss, which makes it the right choice for circuits supplying wet-area equipment or medical IT rooms where lower leakage tolerance is specified. Type A detection covers pulsating DC residual currents from half-wave rectified loads (typical in switching power supplies and variable-speed drives), so it handles the modern load mix better than a Type AC device. The 10 A rating at 30 °C drops to 9.4 A at 40 °C, 9.1 A at 45 °C, 8.7 A at 50 °C, and 8.1 A at 55 °C. ## Panel integration — footprint and clearance Width is 36 mm (2 MW), depth 77 mm, height 90 mm, with an installation depth of 70 mm. The IP20 rating applies only when the distribution board is installed and conductors are connected — so during panel assembly before the cover is on, treat it as a touch-protected device, not sealed. Power supply cord can enter from either top or bottom, and the touch-protection feature is built in (no separate finger duct needed). Halogen-free and silicon-free construction keeps it compliant for clean-room or sensitive-environment panels where outgassing matters.","metaTitle":"Siemens 5SU9156-7VK10 SENTRON RCBO, 10A, 10mA, Type A, 6kA","metaDescription":"Siemens SENTRON 5SU9156-7VK10 RCBO, 2-pole, 10 A rated, 10 mA residual, Type A, 6 kA breaking capacity per EN 60898.

The difference is the residual current rating: the 5SU9156-7VK06 trips at 6 mA, while the 5SU9156-7VK10 trips at 10 mA. If the panel wiring and load leakage profile allow a 10 mA threshold, it's a direct mechanical swap — same width, same depth, same connection scheme."},{"question":"What is the depth of the 5SU9156-7VK10?","answer":"Listed depth is 77 mm, with an installation depth of 70 mm (the portion that sits behind the panel face)."},{"question":"What compliance documentation does Siemens provide for the 5SU9156-7VK10?","answer":"The part carries EN 60898 certification for breaking capacity (6 kA) and is designed to IEC 61346-2 and IEC 81346-2 reference designation systems (function code F).
