Motor circuit breaker for 3.5 A protection
The GV4PE03N is a 3-pole motor circuit breaker from the TeSys Deca range, rated 3.5 A continuous. It sits between the supply and a motor up to 0.75 kW at 400 V AC (or 1.5 kW at 500 V). The electronic thermal-magnetic trip unit gives both overload and short-circuit protection; magnetic trip kicks in at 59 A. Phase failure sensitivity is built in per IEC 60947-4-1, so it catches a lost phase before the motor cooks. That covers most industrial panels with high fault current; you can use it in a line-up without worrying about series rating. For 480Y/277 V UL systems it still holds 35 kA.
Climatic withstand meets IACS; operating altitude up to 5000 m. The EverLink BTR screw terminals accept solid copper up to 95 mm² bottom / 70 mm² top, or flexible up to 70 mm² bottom / 50 mm² top. Tightening torque is 9 N·m for the power terminals. IP40 front face keeps dust out; IK07 impact resistance. Toggle control with 25 cycles/hour max operating rate. 40000 mechanical cycles, same for electrical at AC-3. Fits any mounting position.
