Schneider GV3P73 TeSys Deca Motor Circuit Breaker 62-73A EverLink 50kA

The GV3P73 is a 3-pole thermomagnetic motor circuit breaker from Schneider Electric's TeSys Deca range, providing motor protection across AC networks up to 690 V. Rated at 73 A with an adjustable thermal range of 62-73 A, it handles motors up to 37 kW at 400/415 V and up to 55 kW at 690 V AC. A breaking capacity of 50 kA at 400/415 V and EverLink screw terminals make it well suited to demanding industrial switchboard applications.
