Eaton SR5 Series Fuse, 6.3A Current Rating, 250V AC Voltage - SR-5-6-3A-BK
This fuse provides time-delayed overcurrent protection for low-voltage AC circuits in industrial and electronic systems. Designed to interrupt fault currents while allowing harmless inrush currents to pass, it is intended for installation where controlled, predictable clearance of overloads is required.
Features and Benefits:
• 6.3A rating allows stable protection for moderate-current circuits • 250V AC rating supports standard single-phase mains applications • Time-delay (slow-blow) characteristic tolerates short inrush events • 63A breaking capacity permits safe interruption of substantial faults • Radial leads with 1mmx4.3mm dimensions enable through-hole PCB mounting • Maximum operating temperature +125°C ensures performance in elevated heat
Applications
• Suitable for power supplies with high start-up currents • Ideal for motor control circuits subject to transient surges • Used with consumer appliance PCBs requiring slow-clear protection • Can be used for industrial instrumentation and automation boards • Suitable for replacement in legacy equipment designed for IEC fuses
What speed characteristic does it use for thermal response?
It employs a T-speed time-delay element that resists brief current spikes while opening on sustained overloads.
How is it mounted on printed circuit boards?
The component uses radial lead orientation for through-hole insertion, with leads sized 1mm diameter and 4.3mm length for standard soldering.
What environmental extremes can it withstand during operation?
It is specified to operate down to -40°C and up to +125°C, covering wide temperature ranges encountered in industrial settings.
Which approvals cover its suitability for international electrical designs?
It conforms to recognised standards including IEC 60127-3 and carries approvals from PSE and VDE along with RoHS compliance.
