It's a 3-pole unit with a toggle control, designed for motor protection in industrial control panels. The headline breaking capacity is 100 kA Icu at 220...240 V AC, dropping to 50 kA at 380...415 V AC and 15 kA at 525 V AC. That's enough SCCR headroom for most industrial service-entrance or sub-distribution boards fed by a transformer of moderate impedance. The magnetic trip is set at 480...1120 A, meaning it clears bolted faults fast while riding through normal motor inrush.
Motor power and application fit
The GV4LE115N6 covers a wide motor power band depending on the supply voltage: 37 kW at 400 V, 55 kW at 500 V, and up to 110 kW at 690 V. The trip unit is magnetic-electronic, so it provides both short-circuit and overload protection in a single device. For a 115 A motor circuit breaker, this is the range you'd expect for a 37–55 kW motor at common European voltages. Utilisation category is AC-3 per IEC 60947-4-1, which is the standard for squirrel-cage motors — starting, stopping, and occasional plugging. The electrical durability is 10,000 cycles at AC-3 at 440 V with half-rated current, and 5,000 cycles at full-rated current. Mechanical durability is 40,000 cycles. That's a solid service life for a motor branch circuit in a conveyor, pump, or fan application.
The breaker measures 155 mm high by 81 mm wide by 116 mm deep. The connection pitch is 27 mm without spreaders, expanding to 35 mm with spreaders — important to note when laying out the gland plate and busbar runs in a dense panel. IP40 protection means it's fine inside a clean enclosure but not for washdown areas. The IK07 impact rating handles accidental tool drops. Operating altitude goes to 5000 m, which covers most high-altitude installations without derating. Terminals accept lugs or ring terminals for cable from 1.5 to 95 mm², with tightening torques of 5 N.m for the smaller range and 9 N.m for the larger. That's a robust connection range — enough for the 115 A rating with standard copper cable.
