ECSR12 - 12Amp Fuse

ECSR12 - 12Amp Fuse

The Eaton Edison ECSR12 is a high‑performance, time‑delay fuse designed to deliver reliable circuit protection for demanding industrial and commercial environments. This 12 amp, 600 V AC Class RK5 dual-element fuse is built to handle both overloads and short circuits with precision. Thanks to its “super‑lag” time‑delay feature, the ECSR12 tolerates the high inrush currents that occur when starting motors, powering transformers, or switching inductive loads — avoiding nuisance trips while ensuring essential protection. With a 200 kAIC fault‑clearing capacity, it safely handles extreme fault conditions that could damage equipment or disrupt operations.

Key Features and Benefits

• Time‑Delay “Super Lag” Function: Offers roughly a 10‑second delay at 500% of rated current, giving systems breathing room during high inrush events like motor starts and transformer energizing, reducing unnecessary shutdowns.
• Dual‑Element Fuse Design: Combines overload and short‑circuit protection in a single fuse, extending equipment lifespan and improving operational dependability under variable loads.
• High Interrupt Capacity (200 kAIC): Capable of clearing fault currents up to 200,000 amps, making it suitable for high‑energy environments where safe fault interruption is critical.
• Standard Ferrule‑End Construction: Compatible with standard fuse blocks and holders, making installation and replacement quick and hassle‑free.
• Sturdy Build Quality: Manufactured for extended service life in industrial systems that demand frequent load cycling, ensuring continued performance under heavy use.
