ECSR9 - 9Amp Fuse

ECSR9 - 9Amp Fuse

If you’re looking to protect sensitive equipment from overloads and surges without unnecessary downtime, the ECSR9 fuse delivers dependable current limiting with precision. Engineered for demanding industrial and commercial electrical systems, this 9‑amp, 600 V AC fuse tolerates brief inrush currents — like those from motors, transformers, or HVAC compressors — while still reacting fast to dangerous sustained overloads or short‑circuits. Its compact, finger‑safe body slides neatly into standard fuse holders, allowing quick installation or replacement. With the ECSR9 in place, you’re equipping circuits with reliable, maintenance‑friendly protection that keeps installations safe and running smoothly.

Key Features and Benefits

• Time‑Delay Performance: The fuse tolerates short-term current surges (up to 500% of nominal current for 10 seconds), preventing nuisance trips when systems start or change load — ideal for motor-driven equipment or transformer inrushes.
• Dual‑Element Construction: This design combines overload and short-circuit protection, offering superior defense against both gradual and sudden electrical faults.
• Finger‑Safe, Compact Form Factor: The small, user-friendly size enables easy installation and replacement, while minimizing the risk of accidental contact.
• High Interrupting Capacity (200 kA): Built to handle substantial fault currents, assuring reliable interruption in heavy-duty industrial environments.
• Minimal Maintenance & Long Service Life: With sturdy internal components and the dual-element design, the fuse endures repeated cycling and reduces the likelihood of early replacement.
