RGS15 — 500V class fast‑acting fuse for 250V circuits. Available ratings: 150A, 200A, 225A (common), 250A, 300A, 350A. Key benefits Fast overcurrent response that limits damage to power supplies, controllers, motors, and related equipment. Precise current ratings let you match protection to steady load and startup surge characteristics. Broad 500V class capability engineered for reliable interruption on 250V systems. Compact, robust construction designed for industrial panels and rack mounting; fits standard RGS15 form‑factor installations for quick replacement. Simple swap‑out replacement reduces downtime and keeps maintenance predictable. What it does and why you need it Prevents thermal or electrical damage by interrupting fault currents quickly, reducing repair costs and unplanned outages. Lets you tailor protection to protect sensitive electronics while allowing controlled inrush for motors and drives. Maintains compatibility with existing RGS15 hardware so upgrades or replacements integrate without panel redesign. Key attributes Function: fast‑acting overcurrent interruption for protection of 250V circuits. Compatibility: standard RGS15 form factor and mounting; common 225A option available for inventory simplification. Size and construction: compact profile and rugged build for industrial environments and rack applications. Performance: precise current options and dependable interruption behavior for consistent protection. Typical applications Control cabinets and industrial equipment: protect 230/240V AC power supplies, PLCs, and control electronics from fault currents. Motor drives and inverters: safeguard 250V motor drive inputs and inverter supply lines from overloads and short circuits. DC power systems: protect 250V DC links used in battery chargers, solar inverters, telecom power distribution, and data‑center power equipment. Selection and installation notes Choose the fuse current rating to match nominal load and the required level of protection for startup surges. Verify mechanical mounting and electrical compatibility with your existing RGS15 fuse holders and hardware. Use the common 225A option where standardization across builds reduces spares and simplifies maintenance. RGS15 delivers fast, reliable protection in a compact, compatible package for 250V systems — select the correct rating to balance protection and operational needs.
