The GV4LE03N is a 3-pole motor circuit breaker from the Schneider Electric TeSys GV4 range, rated at 3.5 A continuous current for motor protection.
The 3.5 A In sets the continuous current the breaker will carry without tripping — match this to the motor full-load current. The magnetic trip range of 21...49 A provides instantaneous short-circuit protection; the electronic overload handles the thermal curve. Motor power ratings span 0.55 kW at 400 V up to 2.2 kW at 690 V, so one breaker covers a range of motor sizes depending on line voltage. The utilisation category AC-3 confirms it is rated for switching squirrel-cage motors — starting and stopping under load. Suitability for isolation per IEC 60947-1 means this breaker can serve as a visible-disconnect point — no separate isolator needed upstream.
The GV4LE03N occupies a 81 x 155 x 116 mm footprint on the DIN rail. EverLink BTR screw terminals accept up to 95 mm² on the bottom (load side) and 70 mm² on the top (line side), with tightening torques of 9 N·m for larger cables and 5 N·m for smaller ones. IK07 impact rating handles incidental tool drops during commissioning. Maximum operating rate is 25 cycles per hour — enough for manual start/stop but not for high-speed jogging. Mechanical durability is 40,000 cycles; electrical durability is also 40,000 cycles at AC-3 rated current.
