ECSR30 - 30Amp Fuse

ECSR30 - 30Amp Fuse

The Eaton ECSR30 30‑Amp Time‑Delay Fuse delivers reliable circuit protection for heavy‑duty commercial and industrial power systems. Designed as a Class RK5 dual‑element fuse with a 600 V AC rating, it ensures reliable safeguarding against both overloads and short circuits — while still allowing for temporary inrush currents, such as those seen when motors, transformers, or HVAC systems start up. With a 10‑second time delay at 500 % of rated current, the ECSR30 tolerates brief surges without blowing — yet instantly interrupts dangerous sustained overcurrents. The high interrupting capacity provides additional peace of mind in the event of major fault conditions. Whether you’re outfitting a motor control panel, maintaining a transformer bank, or protecting a distribution panel, this fuse is built to last and perform under demanding conditions.

Key Features and Benefits

• Time‑Delay Dual‑Element Construction: Handles temporary surge currents from motor starts and transformer energizing, while still protecting against sustained overloads and short circuits — helping extend the lifespan of your equipment.
• Finger‑Safe Design: Enhances technician safety during installation and maintenance, minimizing risk of accidental contact.
• Standard Ferrule Ends: Compatible with most common fuse holders for quick, secure replacement and seamless integration with existing panel configurations.
• Durable Under Harsh Conditions: Engineered to maintain performance in high-cycling environments and heavy‑duty applications without degradation.
• High Fault‑Current Capacity: The 200 kAIC rating ensures that the fuse can interrupt even substantial fault currents safely, preserving system integrity.

Where It Works Best

• The ECSR30 is an excellent choice for protecting motor controls, industrial HVAC systems, transformer circuits, and power distribution panels. It’s especially suited for applications where high inrush currents are common — like large motors, compressors, or inductive loads — but where sustained overcurrent could damage equipment or cause downtime. Use this fuse in industrial control systems, manufacturing facilities, commercial buildings, or other installations that demand consistent, dependable circuit protection under heavy use.
