The magnetic trip is adjustable between 300 and 700 A, providing short-circuit protection that coordinates with the motor's starting inrush. The trip unit technology is magnetic electronic — a hybrid approach that uses a magnetic coil for instantaneous fault detection and an electronic module for overload curve shaping. This avoids the thermal drift of bimetal designs and allows tighter protection bands. Dimensions are 155 mm high, 81 mm wide, and 116 mm deep. The grey (RAL 7016) enclosure carries IP40 protection (finger-safe) and IK07 impact resistance. EverLink BTR screw terminals accept cable from 1.5 to 95 mm², with separate torque values for power and control connections. ## Durability and environmental ratings Mechanical durability is 40,000 cycles; electrical durability under AC-3 duty at 440 V is 10,000 cycles at rated current, doubling to 20,000 cycles at half load. Maximum operating rate is 25 cycles per hour — a constraint for frequent start-stop applications. Climatic withstand conforms to IACS (marine environmental testing). Vibration resistance covers 2 to 100 Hz at 0.7 gn, and shock withstand is 15 gn for 11 ms. Certified to EN/IEC 60947-4-1 (motor starters) and EN/IEC 60947-2 (circuit breakers). Fire resistance tested at 960 °C per IEC 60695-2-11. The utilisation category is AC-3 for motor switching and Category A for distribution-level short-circuit protection.","metaTitle":"Schneider Electric GV4LE50B TeSys Deca Motor Circuit Breaker","metaDescription":"Schneider Electric GV4LE50B TeSys Deca motor circuit breaker, 50 A rated current, 3-pole, magnetic electronic trip, 50 kA breaking capacity at 240 V.
