Description
Product Description The TeSys GV3P73 is a heavy-duty thermal-magnetic motor circuit breaker engineered to serve as a complete local control and isolation station for demanding three-phase electric motors. By integrating magnetic protection (against short circuits) and adjustable thermal protection (against prolonged heat overloads) into a unified 55mm wide frame, it eliminates the need for standalone fuse sets. Key Features 3-Pole (3P) Configuration: Provides simultaneous line interruption and multi-phase electrical fault protection across all three live phase inputs. Adjustable Thermal Rating (62A to 73A): Features a front-accessible tuning dial, calibrated to let engineers lock down the overload threshold to the precise Full Load Amperages (FLA) of large machinery. Rotary Handle Interface: Equipped with a thick industrial rotary toggle switch supporting an ergonomic visual readout (ON/OFF/TRIPPED). It can be padlocked directly in the “OFF” position for strict plant Lockout/Tagout (LOTO) requirements. EverLink Connection System: Built with Schneider’s specialized wire-clamping tech that continuously counteracts electrical cable creepage, ensuring terminal tightness over years of use and eliminating hazardous hot-spot arcs. Compatible Mechanisms and Components The high-amperage GV3 mechanical footprint acts as a core anchor inside modular industrial motor control center (MCC) panels: 1. In-Panel Equipment Compatibility TeSys Deca High-Power Contactors: Natively pairs and stacks side-by-side with high-capacity magnetic contactors, specifically matching models LC1D65A up to LC1D80. Using a modular busbar connector hookup creates an ultra-compact, high-power motor starter unit. GV3 Auxiliary Switch Modules: Accepts front-inserting (e.g., GVAE11) or side-clamping (GVAN11) auxiliary logic blocks to feed physical operational telemetry (ON/OFF status) back to automated PLC system processors. Remote Shunt Trips: Can be augmented internally with a GV3AS shunt trip or an under-voltage release block to drop the main breaker automatically from an emergency E-Stop push button across the shop floor. Heavy DIN Mounting Backing: Due to its continuous high vibration tolerance and weight, it mounts safely to specialized heavy-duty 35mm steel DIN rails or screws down via a three-point M4 screw array onto flat panel mounting plates. 2. Heavy Machinery and Mechanical Loads It Protects The high 62A to 73A calibration range renders this MPCB appropriate for protecting massive three-phase induction motor mechanisms operating at 37 kW (50 HP) under standard 400/415V utility feeds, such as: Industrial Raw Material Shredders & Crushers: High-torque mechanical processing drums used in mining, milling, and waste processing centers. High-Horsepower Hydraulic Power Packs: Drives heavy-duty hydraulic pumps used for industrial presses, stamping machines, and large car-assembly lifts. Municipal Water & Sewage Pumps: Heavy fluid transfer stations, high-capacity agricultural irrigation systems, and lift station pumps. Commercial District HVAC Equipment: Massive central cooling fans, heavy industrial air compressors, and centralized building chiller loops.
