Premium Nickel-Plated Outer Shell & Copper Terminals Whole housing adopts anti-corrosion nickel plating treatment to resist moisture, dust and oxidation in harsh outdoor & engine bay environments; thick solid copper threaded terminals optimize electric conductivity, lower heat buildup during long-hour continuous operation and effectively reduce energy loss. Matching lock nuts & insulating gaskets come pre-equipped for seamless installation.
High-Current Load Bearing Structure Optimized internal electromagnetic coil structure supports large amp power switching (available in 200A/300A options), capable of instant power-on to drive winch, hydraulic pump, lift motor and other heavy-load equipment without frequent tripping or overheating issues.
Stable Insulation & Shockproof Design High-density insulating pads separate terminal posts from metal housing to avoid accidental short circuit; stamped steel fixed mounting bracket features pre-cut positioning notches for flexible bolt-on installation on flat or curved mounting surfaces, resisting vibration during vehicle bumpy travels.
Perfect fit for multiple DC-powered equipment: Golf carts, utility carts & small electric vehicles Off-road vehicle electric winch systems, truck/trailer hydraulic tailgate pumps Marine boat onboard pump, anchor winch & auxiliary power control Forklift, stacker, pallet truck starting & motor control circuits Agricultural machinery, RV camper auxiliary power switching systems
Installation Tips 1.Confirm your device working voltage (12V or 24V DC) and rated current before installation to match the relay specification 2.Secure the mounting bracket firmly on clean, grounded metal surface with standard fasteners 3.Tighten terminal nuts properly to avoid loose wiring causing abnormal heat generation 4.Keep wiring away from sharp metal edges and high-temperature engine parts to extend service life
