What the GV4P25B brings to your motor branch
Breaking capacity and fault withstand
At 480Y/277 V UL conditions it still delivers 18 kA — enough for most industrial panels. The 25 A magnetic trip threshold (425 A) ensures fast clearing on short circuits, and the continuous duty rating (IEC 60947-4-1) means it runs at full load without derating.
Built for wet, corrosive mill environments
IP40 front and IK07 impact resistance hold up to a paper mill's steam and splash. Pollution degree 3 allows operation in condensing atmospheres. Climatic withstand per IACS covers salt-mist corrosion common in board plants. These specs reduce unplanned downtime from environmental stress.
Mounting and connection details
EverLink screw terminals accept solid wire up to 95 mm² at the bottom and 70 mm² at the top. Tightening torque is 9 N·m for the larger conductor range, 5 N·m for smaller. Any operating position allowed. The rotary handle gives visible break indication for lockout/tagout — required for isolation per IEC 60947-1.
