Compact, robust, and innovative TeSys GV4 motor protection circuit breaker for motor power up to 115 A / 55 kW. The electronically implemented protection of TeSys GV4 circuit breakers provides excellent precision, wide setting ranges, choice of starting time class (lk 10/20), and low heat losses. The GV4PEM also includes extended protection features and predictive alarm information. TeSys GV4 circuit breakers are available with three different protection features: • GV4L: Short-circuit protection only, when motor overload protection is implemented via a thermal relay, intelligent motor controller, frequency converter, or soft starter • GV4P: Short-circuit and overload protection • GV4PEM: Short-circuit and overload protection with extended protections (stall protection, earth fault, phase asymmetry, prolonged starting) and the option to use the SDx fault separation module Features: • One frame size for motors from 0.25 – 55 kW (0.8 – 115 A) 415 V AC • Available with three different short-circuit withstand ratings: 25, 50, and 100 kA / 415 V • Patented EverLink connection: - Spring mechanism compensates for changes in the conductor - Prevents tripping due to loose connections - Reduces short-circuit risk • Ergonomic knob for easy connection and control with clear trip indication.
