Description
Product Description The TeSys GV3P65 is a heavy-duty thermal-magnetic motor protection circuit breaker designed to handle the high electrical and mechanical demands of large industrial electric motors. Unlike push-button models, it utilizes a robust Rotary Toggle Handle that can be padlocked in the “OFF” position for strict Lockout/Tagout (LOTO) safety compliance during maintenance. Key Features 3-Pole (3P) Configuration: Engineered for the complete control, isolation, and protection of three-phase industrial electrical lines. Adjustable Thermal Setting (48A to 65A): Features a high-capacity current adjustment dial on the front face, allowing an engineer to match the exact Full Load Amperage (FLA) of a heavy motor. EverLink BTR Terminals: Patented screw-tight technology that maintains continuous structural pressure on the power cables, preventing wire creepage and alleviating the hot-spot failures common in high-amperage panels over time. High Breaking Capacity (50kA at 400/415V): Rated to withstand and safely terminate intense short-circuit currents up to 50,000A without compromising the panel box. Phase Failure Sensitivity: Instantly trips the system if any single phase drops offline, preventing the motor from drawing uneven power and melting its internal copper windings. Compatible Mechanisms and Components The GV3 frame size interfaces directly with specific high-power panel elements to construct industrial Motor Control Centers (MCC): 1. In-Panel Component Compatibility TeSys D / Deca Contactors: Pairs seamlessly with high-capacity contactors (specifically the LC1D40A up to LC1D65A models) via a specialized spacer connection block. This combined setup creates an ultra-compact Type 2 coordinated motor starter. GV3 Auxiliary Contacts: Natively accepts front-mounting (e.g., GVAE11) or side-mounting (e.g., GVAN11) auxiliary switch blocks to relay the switch state directly to modern automation controllers or digital PLCs. Shunt Trips & Under-Voltage Releases: Can be retrofitted internally with a GV7 or GV3B shunt trip module to allow automatic emergency-stop tripping from an external emergency push button. Large DIN Rails & Plates: Due to its weight (0.96 kg), it requires heavy-duty 35mm symmetrical DIN rails or direct machine-screw backing onto a flat steel mounting plate. 2. Heavy Machinery and Mechanical Loads It Protects The high 48–65A capacity optimizes this MPCB for heavy industrial three-phase induction motors operating around 30 kW (40 HP) at 400V, including: Large Industrial Air Compressors: High-horsepower air pumps utilized in automotive garages and industrial manufacturing facilities. Heavy Conveyor Systems & Crushers: High-torque motors found in mining operations, material processing plants, and sorting yards. High-Output Water & Wastewater Pumps: Large municipal drainage pumps, clean-water booster pumps, and agricultural irrigation networks. Commercial Chiller & HVAC Compressors: Primary central climate compressors powering massive multi-story office building cooling towers.
