The GV4L25N6 is a 3-pole motor circuit breaker from the TeSys GV4 range, rated at 25 A continuous current (In) and designed for motor protection under AC-3 utilisation category per IEC 60947-4-1. The 25 A rating means it directly protects a motor drawing up to that full-load current — for a 400 V supply that translates to roughly 5.5 kW, while at 690 V it covers up to 7.5 kW. The magnetic-electronic trip unit provides adjustable magnetic tripping between 150 and 350 A, so you set the instantaneous pickup to ride through motor inrush without nuisance trips. The part is rated for isolation (IEC 60947-1), so it doubles as a disconnect under load.
Connection pitch is 27 mm without spreaders and 35 mm with them, which matters when laying out busbars or cable ducts in a crowded enclosure. Terminals accept lugs or ring terminals for cable sizes from 1.5 to 95 mm², with tightening torques of 5 N·m for smaller cables and 9 N·m for the larger ones. The IP40 front face and IK07 impact rating mean it is suited for general industrial panel environments where occasional tool drops or dust ingress are concerns. Pollution degree 3 confirms it for conductive environments typical of factory floors.
Climatic withstand conforms to IACS for marine environments. Fire resistance is tested to 960 °C per IEC 60695-2-11. Storage temperature range is -50 to 85 °C.
