ECSR35 - 35Amp Fuse

ECSR35 - 35Amp Fuse

The ECSR35 35 Amp time-delay fuse is engineered to deliver reliable, heavy-duty circuit protection for demanding industrial and commercial electrical systems. Designed to handle both prolonged overloads and sudden short circuits, this Class RK5 dual-element fuse is ideal when you need dependable performance under tough conditions. With a 600 V AC rating and a high interrupt capacity, the ECSR35 gives you peace of mind when wiring motors, HVAC systems, control panels, transformers, or automation panels. Its time-delay design tolerates inrush currents without nuisance blowing, helping you avoid unnecessary downtime and minimizing maintenance hassles.

Key Features and Benefits

• Time‑Delay Protection: Allows temporary current surges — such as a motor’s start‑up or an HVAC unit’s compressor startup — without tripping, reducing unnecessary fuse replacements.
• Dual‑Element Design: Provides layered defense — one element handles prolonged overload, the other acts immediately for short-circuit events, boosting overall system safety.
• Finger‑Safe Ferrule Ends: Ensures safer handling and easy compatibility with standard fuse holders, making installation and maintenance safer and faster.
• High Interrupt Capacity: With a 200,000‑amp interrupt rating (200 kAIC), it can safely clear large fault currents common in heavy-duty industrial and commercial systems.
• Durable Construction: Built to endure frequent cycling and harsh operating environments, offering long service life even under continuous load conditions.
