It also carries UL1077 recognition for supplementary protection in North American panels. The F2 characteristic is a fast-acting curve with a defined short-circuit withstand, suited for protecting semiconductor loads or sensitive control circuits where a standard B or C curve would let through too much energy. The auxiliary NO contact gives a positive status signal back to the PLC or safety circuit — no separate add-on needed for that feedback path. ## Mounting and Integration — DIN Rail, 1 MW Unit, IP20 Mounts horizontally or vertically with no derating penalty at rated current. ## Compliance and Approvals — Dual Standard Footprint Rated under IEC / DIN EN 60934 as a device circuit breaker for equipment (manual reset, overcurrent and short-circuit protection) and UL1077 as a supplementary protector. Vibration tested per IEC 60068-2-6. Mechanical service life is 6,000 operating cycles typical — adequate for maintenance switching and fault clearing, not for continuous load-break duty.","metaTitle":"Siemens 5SY1704-4 SENTRON Device Protection Switch, F2 4A","metaDescription":"Siemens 5SY1704-4 SENTRON 1-pole device protection switch, F2 characteristic, 4A, 230V AC/60V DC, IEC 60934 & UL1077.
