LS Overload Relay 1.6-2.5A

Description

Product Description The TeSys Deca GV3P501 is a 3-pole thermal-magnetic motor circuit breaker engineered to protect large industrial motors. While it retains the 37A to 50A tuning range, rotary handle interface, and internal protection curves of the standard GV3P50, it features a specialized terminal layout intended for ultra-clean, wireless panel builds. Key Features Direct-Assembly Framework (No Downstream Block): Built with open EverLink BTR connectors on the top (incoming power line) side but features specialized raw contact pins underneath. It plugs straight into a companion contactor, saving space and eliminating structural jumper cables. Tunable Thermal Overload Dial (37A to 50A): Equipped with an analog tuning dial on the front face to perfectly align trip sensitivities with the Full Load Amperage (FLA) of large machinery. Rotary Lockable Handle: Features a heavy-duty rotary toggle knob indicating circuit state (ON / OFF / TRIPPED) that supports padlocking to fulfill plant Lockout/Tagout (LOTO) requirements. 50kA Fault Breaking Capacity: Rated to safely intercept, isolate, and snuff out explosive short-circuit current surges up to 50,000A under standard 400/415V lines. Compatible Mechanisms and Components The unique direct-plug layout of the GV3P501 dictates a highly specific component configuration: 1. Seamless Contactor Integration TeSys Deca Contactors (LC1D40A to LC1D80A): This circuit breaker is specifically designed to slide directly into high-power contactors like the LC1D40A, LC1D50A, or LC1D65A. Because it anchors directly into the contactor’s input ports, it reduces installation labor times and saves significant vertical panel space. 2. Standard Logic Modules GVAE11 / GVAN11 Auxiliaries: Natively accepts top-mount or side-mount auxiliary contact blocks to feed operational position telemetry (ON/OFF status) back to a centralized automation PLC. GVAD1010 Fault Blocks: Snaps onto the side to signal the control center only when the breaker has tripped due to an active overload or short circuit. Machinery and Mechanical Loads It Protects When mounted directly to its companion contactor, the 37–50A thermal band optimizes this unit for controlling and safeguarding standard three-phase electric induction motors operating at 22 kW (30 HP) under 400/415V utility lines: Heavy Industrial Ventilation Fans: Found in chemical treatment plants, mining ventilation grids, and commercial building HVAC shafts. High-Torque Conveyor Loops & Mixers: Powers heavy assembly-line gearboxes, raw material packaging plants, and sorting yards. Fluid Circulation & Wastewater Pumps: Protects municipal drainage setups, commercial clean-water booster pumps, and industrial cooling towers.
