It carries a 35 kA SCCR at 240 V AC UL and 50 kA Icu at 220/240 V AC IEC, giving it strong fault-clearing capability for industrial distribution. The thermal-magnetic trip unit offers overload and short-circuit protection, with magnetic tripping set at 850 A. Phase failure sensitivity (per IEC 60947-4-1) and suitability for isolation (IEC 60947-1) are included as standard. The breaker is rated for AC-3 switching duty, covering direct-on-line motor starts. Electrical durability is 20,000 cycles at rated current under AC-3, and 10,000 cycles at twice rated current. Mechanical life is 40,000 cycles. Maximum operating rate is 25 cycles per hour, which suits typical motor control panels without excessive switching. Dimensions: 6.7 in (171 mm) high, 3.2 in (81 mm) wide, 4.6 in (116 mm) deep. Color: gray RAL 7016. Enclosure rating IP40 with IK07 impact resistance. Pollution degree 3. Operating altitude up to 5000 m. The EverLink screw terminals accept conductors up to 95 mm² (rigid) on the load side and 70 mm² (flexible) on the line side. Tightening torque is 79.7 lbf·in (9 N·m) for the main terminals.","metaTitle":"Schneider GV4PB50B TeSys GV4 Motor Circuit Breaker, 50A, 3P","metaDescription":"Active 50A motor circuit breaker from TeSys GV4 line. 35 kA SCCR at 240V UL, thermal-magnetic trip, IP40.
