Commonly deployed in manufacturing plants and energy infrastructure, this breaker handles 21A loads while maintaining IP20 protection rating. Its C-curve tripping mechanism provides balanced protection for motor circuits prone to temporary inrush currents. The 1 NO contact facilitates status monitoring in PLC-controlled systems. Users report fewer nuisance trips compared to standard breakers when protecting HVAC units or conveyor belt motors.
Engineered for demanding environments, the GV2-S21C combines 20,000 mechanical operations lifespan with vibration-resistant construction. The thermal-magnetic trip unit maintains accuracy across temperature ranges from -25°C to +70°C. Compatible with Schneider’s TeSys contactors and Modicon PLCs, it forms part of integrated safety systems. Redundant mounting points allow panel installation flexibility while preserving DIN rail compatibility.
Key advantages include:
- Optimized trip characteristics for industrial motor loads
- Space-saving design fits crowded control cabinets
- Visual indicator shows trip cause at a glance
- Quick-connect terminals reduce installation time
- Meets IEC 60947-2 standards for industrial circuit breakers
