What the GV4PB115N Is and Does
The GV4PB115N is a 115 A, 3-pole motor circuit breaker in the TeSys GV4 range. It provides combined overload and short-circuit protection via an electronic thermal-magnetic trip unit with fixed magnetic tripping at 1955 A. The utilization category AC-3 matches motor switching duty. Breaking capacity reaches 65 kA SCCR at 240 V AC (UL 489) and 100 kA Icu at 220/240 V AC (IEC), allowing direct installation on high-fault-capacity industrial panels without upstream fusing in many cases.
The 115 A line-rated current sets the continuous load limit. The magnetic trip is fixed at 1955 A. EverLink screw terminals accept up to 95 mm² rigid bottom connection and 70 mm² top. Torque settings are 44.3 lbf·in for smaller conductors and 79.7 lbf·in for the main power circuit. With IP40 enclosure and IK07 impact resistance, the unit is suitable for clean industrial cabinet environments. Pollution degree 3 confirms operation in typical factory atmospheres.
Dual-certified under UL 489 and CSA C22.2 No 5 for North America, plus IEC 60947-1/-2/-4-1 for global panels. Fire resistance tested at 960 °C (IEC 60695-2-11).
