MOTOR CIRCUIT-BREAKER TESYS 63-73A, 37kW 400V, 50kA/400V

The TeSys GV3 motor protection circuit breaker is easily mounted on a DIN rail and saves space with a compact width of only 55 mm, suitable for various types of motor starters. The range includes circuit breakers with differential protection in addition to short-circuit and overload protection, or short-circuit protection only, up to 80 A / 45 kW / 400 V. The main circuit of the breaker features EverLink™ terminals that ensure a long-lasting and secure cable connection without the need for retightening or problems caused by loose connections. EverLink terminals reduce failures of conductors and components due to overheating at connections, as well as unwanted tripping of breakers, fire risks, and short-circuit hazards. The breaker has a three-position rotary handle (on/off/trip), a lock for the off position, and an optional door-mounted shaft. The GV3 series uses common auxiliary and alarm contacts, trip indicators, and other accessories compatible with GV2 circuit breakers.
