Telemecanique Overload LR2 2.5-4A

Description

roduct Description The TeSys GV3P18 is a 3-pole thermal-magnetic manual motor starter. By packaging specialized motor protection elements directly into a standardized 55mm wide frame, it delivers full-spectrum defenses against common electrical faults without requiring external inline overcurrent fuses. Key Features 3-Pole (3P) Configuration: Simultaneously breaks and shields all three incoming live phase lines to preserve balanced distribution across three-phase motor windings. Tunable Thermal Dial (12A to 18A): Features a front-accessible, analog tuning dial that allows an engineer to dial in the precise full-load current (FLA) of the machinery. Rotary Handle Control: Built with a rugged, three-position rotary knob (ON / OFF / TRIPPED). The handle can be physically padlocked in the “OFF” position, serving as a secure disconnect for strict plant Lockout/Tagout (LOTO) safety protocols. EverLink BTR Terminals: Utilizes Schneider’s patented wire-clamping technology. An internal spring mechanism counteracts copper wire “creepage” (loose settling over time) caused by machinery vibrations, entirely preventing hot-spot panel fires. Extreme Breaking Capacity (100kA): Because the load current is optimized, this breaker can safely extinguish intense short-circuit spikes up to a massive 100,000A at 400/415V without failing or breaking down. Compatible Mechanisms and Components The specialized current/frame footprint of the GV3P18 integrates cleanly with standard industrial automation control gear: 1. In-Panel Equipment Compatibility TeSys Deca Contactors: Natively pairs side-by-side or stacks with magnetic contactors like the LC1D18 or LC1D25 using a specialized busbar link connector. This creates an integrated, space-saving motor starter block. GV3 Auxiliary Signal Modules: Accepts front-mounting (e.g., GVAE11) or side-clamping (GVAN11) auxiliary blocks to push real-time physical telemetry (ON/OFF status) directly to remote industrial PLCs. Undervoltage / Shunt Trips: Can be augmented with a GV3AS shunt trip internally, allowing an emergency stop circuit or safety relay to snap the breaker open automatically from across the plant floor. 2. Machinery and Mechanical Loads It Protects The 12A to 18A calibration range renders this MPCB ideal for protecting standard three-phase electric induction motors operating at 7.5 kW (10 HP) under standard 400/415V conditions, including: Industrial Machining Equipment: Protects the individual motors running industrial pillar drills, localized cutting tools, and small milling lathes. Conveyor Sorting Systems: Drives mechanical assembly loops, packaging lanes, and factory sorting belts. Fluid Transfer Pumps: Safeguards chemical dosing pumps, specialized booster pumps, and small hydraulic units. Commercial Ventilation Fans: Runs exhaust air fans, centrifugal kitchen smoke extractors, and air curtains drawing under 18 Amps.
