ECSR8 - 8Amp Fuse

ECSR8 - 8Amp Fuse

The Eaton ECSR8 is a high‑performance, 8 amp time‑delay current‑limiting fuse built for the demands of industrial and commercial electrical systems. Engineered with a dual‑element design, this Class RK5 fuse provides dependable protection against both overloads and short circuits, while offering a built-in delay to tolerate temporary surges — such as those from motor startups — without unnecessary disruptions. With a 600 V AC voltage rating and an interrupt rating of 200,000 amps, the ECSR8 delivers consistent, dependable operation even in heavy-duty environments. Whether you’re safeguarding control panels, motor drives, or power distribution boards, this fuse blends safety and performance so your equipment stays protected and productive.

Key Features and Benefits

• Time‑Delay Protection: The ECSR8 can sustain short-term surges (up to 500% of rated current) for about ten seconds, making it perfect for inductive loads like motors or compressors that draw high inrush current during startup.
• Dual‑Element Construction: Combining overload and short-circuit protection in one unit, it sharply reduces the risk of damage to wiring and connected devices.
• Finger‑Safe, Ferrule‑End Design: Ensures safe handling and seamless compatibility with standard fuse holders in commercial panels.
• Reliable Performance Under Continuous Use: Built to endure frequent start/stop cycles and heavy-duty operation, making it a trustworthy choice for “always-on” equipment.
