It protects motor branch circuits against short-circuit and overload, with a magnetic trip unit that operates between 12 and 28 A. The breaking capacity reaches 120 kA Icu at 220...240 V AC, dropping to 10 kA at 660...690 V AC — enough to clear a high-fault utility feed without upstream fuses. It carries motor power ratings from 0.25 kW up to 1.5 kW depending on line voltage (400...690 V, 50/60 Hz). The toggle control and EverLink BTR screw terminals accept cables up to 95 mm² on the bottom and 70 mm² on top. Tightening torque is 9 N·m for the larger cables, 5 N·m for smaller ones. The unit fits any operating position and is rated for altitudes up to 5000 m.
The GV4LE02S mounts directly to a DIN rail or panel plate. Its 81 mm width and 155 mm height fit standard TeSys Deca backplate cutouts. The IP40 front face and IK07 impact resistance are fine for enclosed industrial panels — not for washdown zones. Power dissipation per pole is 6.1 W at rated current, so three poles total about 18.3 W. The unit is rated for continuous duty per IEC 60947-4-1.
Compliance documentation includes IEC 60947-2 and IEC 60947-4-1 certification. The part carries a suitability-for-isolation marking per IEC 60947-1. Climatic withstand conforms to IACS, and fire resistance is tested to 960 °C per IEC 60695-2-11. Storage temperature range is -50 to 85 °C, operating -25 to 70 °C.
The magnetic trip range of 12...28 A means the instantaneous short-circuit trip is adjustable within that band — set it to match the motor's locked-rotor current. For a 0.25 kW motor at 400 V, that is typically around 4-5 A locked-rotor, so the lower end of the trip range provides adequate protection. Electrical durability is 40,000 cycles at AC-3 duty (motor switching) at 440 V, both at rated current and at half-rated current. Mechanical durability matches at 40,000 cycles. Maximum operating rate is 25 cycles per hour — fine for a pump or fan start, not for a high-speed indexing application. Vibration resistance per IEC 60068-2-6: ±1 mm at 2...13.2 Hz, 0.7 gn at 13.2...100 Hz. Shock resistance: 15 gn for 11 ms. This is typical for industrial cabinet mounting on a machine frame or near a conveyor drive.
