That dual rating lets you use the same 5SY6111-7 across a light commercial board and a heavy industrial panel without swapping parts. At 18 mm wide (1 MW), it occupies one slot on a standard DIN rail. Mounting position is any orientation, so you can lay it sideways in a shallow enclosure if needed. ## Environmental and construction notes Rated for -40 °C to 75 °C ambient, with humidity derating above 55 °C (95% RH at 55 °C, dropping to 35% at 75 °C). Halogen-free and silicon-free construction — relevant if you're putting this in a clean room or a sealed enclosure where outgassing matters. Sealable terminals let you lock the cover after commissioning to prevent tampering.","metaTitle":"Siemens 5SY6111-7 SENTRON MCB, 1P C-Curve, 6kA/30kA","metaDescription":"Siemens 5SY6111-7 SENTRON miniature circuit breaker, 1-pole C-curve, 6kA (EN 60898) / 30kA (IEC 60947-2). 18mm wide, IP20.

The 30 kA rating also applies at 60 V DC per IEC 60947-2."},{"question":"Will the 5SY6111-7 drop into a panel specified around the 5SY4140-7?","answer":"Both are 1-pole SENTRON MCBs on an 18 mm footprint, so the mechanical fit is identical. The difference is the breaking capacity: the 5SY6111-7 carries the higher 30 kA (IEC 60947-2) rating versus the 5SY4140-7's lower interrupting rating. If the panel's fault-current study calls for 30 kA, the 5SY6111-7 is the correct drop-in; if the spec was written around a lower-rated breaker, verify the fault level before substituting."},{"question":"Where can I buy the 5SY6111-7 and how is it quoted?","answer":"Sourced through independent distribution channels.
