ECSR50 - 50Amp Fuse

ECSR50 - 50Amp Fuse

Meet the Eaton Edison ECSR50 — a dependable, high-capacity time-delay fuse built to keep your heavy-duty power systems safe and running smoothly. Designed for commercial and industrial environments, the ECSR50 handles 50 amps at 600 volts AC and delivers reliable protection where it matters most. Thanks to its dual‑element, time-delay construction, it tolerates the high inrush currents typical when motors or transformers power up — without nuisance tripping. With an interrupting capacity of 200,000 amps, it stands ready in high-fault scenarios. Whether you’re safeguarding large motors, industrial transformers, or power distribution panels, this fuse offers precise and lasting protection.

Key Features and Benefits

• Time‑Delay Performance: The built-in delay handles startup surges from motors and transformers without false trips — so your equipment can power up safely.
• Dual‑Element Design: Offers layered, trustworthy defense against both prolonged overloads and sudden short circuits, helping preserve the lifespan of connected equipment.
• High Interrupting Capacity (200 kAIC): Provides critical protection in environments where fault currents can spike high, giving added safety where standard fuses might fail.
• Ferrule‑End Construction: Fits securely in standard fuse holders for quick, hassle-free installation — ideal for retrofit or new installations alike.
• Finger‑Safe, Non‑Indicating Format: Keeps user safety in mind — no exposed live ends and no unnecessary indication components, just efficient, clean functionality.
