The Siemens 5SY4118-7, part of the Sentron 5SY4 frame series, is a miniature supplementary protector designed for electrical circuit protection. It operates at 400V AC with a current rating of 15A and features a 1-pole configuration.
This protector utilizes a thermal magnetic trip mechanism with a trip range of 16.95 to 21.75 A and an interrupt rating of 10 kA at 50 Hz. It is designed for DIN rail mounting, facilitating easy installation in control panels and distribution equipment. The enclosure is rated IP20, offering protection against finger contact.
Key features include a Type C characteristic, suitable for general device protection in control circuits, and excellent current limiting and selectivity characteristics. The dimensions are 90 mm H x 18 mm W x 70 mm D. It operates within a temperature range of -25 to 45 deg C.
Compliance agencies include CCC, CE, EAC, RCM, UR, and VDE. The RoHS status is reported as RoHS3 Compliant, MSL is 1 Unlimited, and REACH is Unaffected, though these are treated with low confidence due to lack of verification.
