The F2 tripping characteristic means it's designed for short-circuit and overload protection of control circuits, solenoids, and contactor coils where inrush isn't extreme but a fast trip on a hard fault is wanted. It's built to IEC / DIN EN 60934 and UL1077, so it qualifies as a supplementary protector in UL panels. Width is 18 mm — one modular unit — so it takes a single slot on the DIN rail. That's a standard compact footprint; it leaves room for gland plates and wire bending space in a shallow enclosure. Mounting position can be horizontal or vertical, and the supply cord can enter from any side, which helps when you're routing bundles in a crowded panel. The 1 A rating is at reference temperature. At 35 °C it's 0.97 A, at 40 °C it's 0.92 A, at 45 °C it's 0.89 A, at 50 °C it's 0.86 A, at 55 °C it's 0.84 A, and at 60 °C it's 0.81 A. Certified to IEC / DIN EN 60934 (equipment circuit breaker standard) and UL1077 (supplementary protector). That dual footprint means it's accepted in both IEC and North American panels as a branch-circuit supplementary protector. Halogen-free and silicon-free construction, IP20 finger-safe terminals. Vibration resistance per IEC 60068-2-6 is confirmed.","metaTitle":"Siemens 5SY1701-4 SENTRON Device Protection Switch, 1A F2, 1","metaDescription":"Siemens 5SY1701-4 SENTRON device protection switch, 1-pole with auxiliary switch (1P+AS), rated 1 A AC / 60 V DC, F2 characteristic.

It's not a motor-protective curve; use it for control-circuit and equipment protection."},{"question":"What compliance documentation does Siemens provide for 5SY1701-4?","answer":"The switch carries IEC / DIN EN 60934 and UL1077 certifications. It's halogen-free and silicon-free. Full RoHS and REACH declarations are available from Siemens documentation."},{"question":"Where can I buy 5SY1701-4 and get current pricing?","answer":"Sourced and quoted to order against an RFQ through independent distribution.

The 5SY1701-4 is rated 1 A with an F2 characteristic and integrated auxiliary switch (1P+AS); the 5SY4101-7CV is a different rating and characteristic.
