At 0.5 A, that magnetic threshold sits around 2.5 to 5 A, so it clears fast on a hard short but rides through the brief start-up surge of a small motor or solenoid. ## Breaking capacity — which standard governs your panel This breaker carries four breaking-capacity ratings, and the right one depends on the standard your panel is built to. Per EN 60898 it is rated 6 kA — the common domestic and light-commercial benchmark. For DC circuits, it is rated 15 kA at 72 V DC per IEC 60947-2. And for UL 1077 / CSA C22.2 No. 235 it is rated 5 kA at AC — the North American supplementary-protector standard. The 30 kA IEC figure gives real headroom in an industrial distribution board with a large upstream transformer. ## Panel integration — DIN rail, 4 width units, any position Touch protection is built in. The breaker is sealable — useful for installations where tamper-proofing the setting is required. ## Environmental range and material compliance Rated for ambient temperatures from -40 °C to +75 °C, with humidity derating: max 95% RH up to 55 °C, tapering to 35% RH at 75 °C. Overvoltage category III suits fixed-installation distribution boards.","metaTitle":"Siemens 5SY6605-7 SENTRON MCB, 4P C 0.5 A, 6 kA","metaDescription":"Siemens 5SY6605-7 SENTRON miniature circuit breaker, 4-pole 3P+N, C-curve, 0.5 A, 400 V AC, 6 kA (EN 60898) / 30 kA (IEC 60947-2).

It is quoted to order against an RFQ — availability and current pricing are confirmed at quote time, including for volume or blanket-order requirements."},{"question":"When sourcing 5SY6605-7, what is the closest functional second-source — 5SY6602-8?","answer":"The 5SY6602-8 is a peer in the same SENTRON 5SY6 family, but it is a 2-pole breaker with a different current rating and tripping characteristic. The 5SY6605-7 is 4-pole (3P+N), C-curve, 0.5 A. The 5SY6602-8 will not drop into a panel wired for 3P+N without rewiring the neutral and phase conductors."},{"question":"What is 5SY6605-7's listed depth (76 mm) on this component line?","answer":"The depth is 76 mm, with an installation depth of 70 mm behind the panel surface."},{"question":"What is 5SY6605-7's listed width (72 mm) on this component line?","answer":"The width is 72 mm, which corresponds to 4 width units (4 x 18 mm) on a standard DIN rail."},{"question":"Will 5SY6605-7 drop into a panel that was specified around 5SY6602-8 without rewiring?","answer":"No. The 5SY6605-7 is a 4-pole (3P+N) breaker, while the 5SY6602-8 is 2-pole. The panel wiring and busbar arrangement would need to be changed to accommodate the additional poles and the neutral conductor switching function."},{"question":"What compliance documentation does this brand provide for 5SY6605-7 (RoHS, REACH, UL, IEC)?","answer":"The breaker carries ratings per EN 60898 (6 kA), IEC 60947-2 (30 kA AC, 15 kA DC), and UL 1077 / CSA C22.2 No. 235 (5 kA). It is halogen-free and silicon-free, which supports RoHS/REACH compliance.
