Siemens 5SY62037 Circuit Breaker - Thermal Magnetic 3A 400V 2-Pole The Siemens 5SY62037 is a 2-pole miniature circuit breaker from the SENTRON 5SY6 series, designed for IEC supplementary protection against overcurrents in industrial and commercial circuits. It operates at a rated voltage of 400V AC with a 3A current rating and utilizes a thermal magnetic protection mechanism with a C-curve tripping characteristic to handle moderate inrush currents. The compact unit measures 3.622 x 1.575 x 3.307 inches, weighs 0.677 lb, and features screw-type terminals for secure feed-thru connections, housed in an IP20-rated enclosure. This breaker complies with IEC 60898 standards, offering an interrupting capacity of 6kA at 400V AC and a mechanical service life of 20,000 switching cycles. Typical applications include general-purpose circuit protection in industrial control panels, commercial distribution boards, and machinery requiring reliable overcurrent interruption.
