What the 115 A rating means for your motor branch
The GV4L115S is a 3-pole motor circuit breaker from the TeSys Deca range, rated 115 A continuous and built for motor protection under IEC 60947-4-1 and IEC 60947-2. That 115 A is the thermal-magnetic continuous current — it carries the full motor load without nuisance tripping, while the magnetic trip unit operates between 690 and 1610 A to handle short-circuit events. For a 400 V supply, this breaker covers motor power from 37 kW up to 55 kW depending on the exact voltage and configuration; at 690 V it can handle up to 110 kW. The breaking capacity is substantial: 120 kA Icu at 240 V, 100 kA at 415 V, and still 10 kA at 690 V.
The breaker measures 81 mm wide, 155 mm high, 165 mm deep — a standard panel footprint for this class. It accepts EverLink BTR screw terminals: top side takes 1.5–70 mm² solid or 1.5–50 mm² flexible; bottom side takes 2.5–95 mm² solid or 2.5–70 mm² flexible. Tightening torque is 9 N·m for the larger cable range, 5 N·m for the smaller. IP40 enclosure protection means it's suited for clean indoor panels — not washdown environments.
What the standards tell you
Compliance with IEC 60947-4-1 (motor starters) and IEC 60947-2 (circuit breakers) means this single device combines motor protection and short-circuit protection in one package — no separate contactor needed for the protection function, though a contactor is still required for normal switching duty. Electrical durability is 10,000 cycles at AC-3 at 440 V at half rated current, and 5,000 cycles at full rated current — enough for most fixed-speed motor applications.
