Place of Origin: Germany

S403M-CA

HS Code: 85362000 (miniature circuit-breaker, for reference only, subject to local customs verification)
Operating Temperature: -25 °C to +55 °C ambient operating temperature; storage temperature ranges from -40 °C to +70 °C
Rated Voltage: 240-415 V AC, rated insulation voltage 440 V AC, 50-60 Hz
Rated Current: Nominal rated current according to suffix A; C-curve electromagnetic tripping range 5-10 In; rated short-circuit breaking capacity Icn 10 kA at 415 V AC
Function: Implements thermal overload protection via bimetallic strip for long-time over-current conditions, and electromagnetic instantaneous tripping for short-circuit fault events. It adopts energy-limiting design to suppress fault current rise and reduce impact on downstream equipment. Front-panel red-on/green-off indicator shows actual contact status for quick on-site fault judgement. Finger-safe IP20 terminals accept copper conductors for incoming and outgoing wiring. It supports standard DIN-rail mounting inside electrical cabinets with arbitrary installation orientation. It provides circuit isolation capability for maintenance work. Suitable for three-phase load protection of industrial machinery, control cabinet power supply and auxiliary motor circuits. This device fulfils industrial low-voltage distribution safety requirements and carries CE certification.
Humidity Rating: 5-95 % non-condensing relative humidity for operation.
Installation: Standard 35 mm DIN-rail mounting; screw-type terminals for cable connection; multi-unit side-by-side assembly allowed within distribution cabinets.
