ECSR70 - 70Amp Fuse

ECSR70 - 70Amp Fuse

Give your industrial or commercial electrical system the dependable protection it needs with the Eaton Edison ECSR70 fuse. Engineered for high-load environments and circuits subject to motor starts, transformer energizing, or other heavy inrush conditions, this dual‑element, time‑delay fuse delivers steady, reliable performance — guarding against both sustained overloads and sudden short circuits. Its blade‑end configuration ensures a secure, vibration‑resistant fit in heavy-duty fuse holders, while the high interrupt rating provides the peace of mind you want in demanding fault scenarios.

Key Features and Benefits

• Time‑Delay Performance: Designed to tolerate brief current surges — such as motor or transformer inrush — without tripping prematurely, while still protecting against prolonged overloads.
• Dual‑Element Design: Offers accurate and consistent response across a wide range of fault conditions, achieving reliable protection from overloads to short-circuits.
• Blade‑End Construction: Delivers a secure, stable connection that resists loosening due to vibration — essential for industrial panels and machinery installations.
• High Interrupting Capacity: With a 200,000‑ampere interrupt rating (200 kAIC), this fuse handles serious fault currents — making it suitable for electrical systems where safety can’t be compromised.
• Compact and Lightweight: At just 7.88″ long and 0.38 lb, the ECSR70 fits into tighter enclosures and is easier to handle and install than many comparable fuses.

Where It Works Best

• The ECSR70 is ideal for applications such as motor control centers, HVAC systems, transformer circuits, lighting panels, and industrial machinery — especially where high inrush currents or variable loads are expected. It performs extremely well in motor-driven equipment, commercial heating or cooling systems, and large lighting arrays. If you’re managing power distribution in factories, warehouses, or commercial buildings where reliability and safety are non‑negotiable, this fuse stands out as a smart, long-lasting choice.
