Rated for 230 V AC at 50/60 Hz and 60 V DC, with a maximum DC operating voltage of 72 V and single-phase AC up to 250 V. The breaking capacity is 3 kA AC per IEC 60934, and it also carries a UL1077 listing for supplementary protection in North American panels. Mounting can be horizontal or vertical. The F2 characteristic is a fast-acting curve designed for protecting semiconductor loads, sensitive electronics, or circuits where the inrush current is low but a short-circuit must be cleared rapidly. It sits between the standard F characteristic and the ultra-fast gG/gL fuse curve. For a 6 A rating, expect magnetic trip at roughly 8–12 times rated current (48–72 A), which keeps downstream silicon from seeing a prolonged fault. Thermal influence matters: the device is calibrated at 30 °C and 85% relative humidity, but derates at higher ambient temperatures — at 60 °C and 20% rF the effective trip current shifts. If the panel runs hot, account for the derating curve in the datasheet. ## Integration and compliance notes IP20 rated — suitable for dry indoor enclosures only; no washdown rating. Pollution degree 2 (normal factory environment, non-conductive contamination). Sealable per, allowing the actuator to be locked in the OFF position with a padlock for lockout/tagout procedures. The top and bottom terminals are not combined, so each conductor lands on its own clamp — no shared busbar hole. Neutral conductor is not switched.","metaTitle":"Siemens 5SY1706-4 SENTRON Device Protection Switch, 6A F2, 1","metaDescription":"Siemens 5SY1706-4 SENTRON device protection switch, 1-pole with auxiliary NO contact, 6A, F2 characteristic, 230V AC / 60V DC, 3 kA Icn.

It is halogen-free and silicon-free. Full RoHS and REACH declarations are available from Siemens upon request as part of the standard documentation package."},{"question":"What is 5SY1706-4's listed depth (76 mm) on this component line?","answer":"The overall depth is 76 mm, with an installation depth of 70 mm behind the panel face. The width is 18 mm (one modular unit) and the height is 90 mm."},{"question":"Will 5SY1706-4 drop into a panel that was specified around 5SL6006-7 without rewiring?","answer":"Both are 1-pole, 18 mm wide DIN-rail devices, so the physical footprint is the same. However, the 5SY1706-4 has an F2 characteristic with an integrated auxiliary NO contact (1P+AS), while the 5SL6006-7 is a standard B-curve MCB without an auxiliary. If the panel wiring expects the auxiliary contact for status feedback, the 5SY1706-4 is a functional upgrade; if no auxiliary is needed, the 5SL6006-7 may be a simpler drop-in. Verify the trip curve and auxiliary wiring before substitution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SY1706-4","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SY1706-4 when reusing this data.
