Eaton Time Delay Radial Lead Fuse 630mA 250V AC SR-5-630MA-BK

Eaton SR-5-630MA-BK is a time delay fuse with a 630mA current rating and 250V AC voltage, designed with radial leads for through-hole mounting. This fuse protects low-current circuits that experience temporary surges by providing delayed interruption to avoid nuisance tripping while safeguarding downstream components from sustained overloads.

The fuse features a T-speed time delay that reduces false trips from inrush currents commonly seen in transformer and power supply applications. It has a breaking capacity of 35 amps, enabling it to clear fault currents quickly and protect equipment effectively.

Its compact design includes a diameter of 8.5 mm, height of 7.6 mm, and length of 7.37 mm, allowing it to fit into dense PCB assemblies. The radial leads have a diameter of 1 mm and length of 4.3 mm, suitable for insertion into through-hole boards or terminal blocks.

Operating temperature ranges from -40°C to +125°C, making it suitable for harsh industrial and commercial environments. It is compliant with international standards including IEC 60127-3, IEC 60068-2-20, and carries VDE, RoHS, and PSE approvals, ensuring reliability and environmental safety.

Typical applications include protection of inrush-prone power supplies and transformers, control panels in automation systems, and consumer electronic modules requiring miniature fuses. Eaton, formerly known as Bussmann, is a reputable brand in electrical protection devices.

The fuse provides reliable overcurrent protection for circuits with inrush current surges. Rated at 630 milliamps with a time-delay T-speed characteristic to prevent nuisance tripping. Equipped with 1mm diameter radial leads 4.3mm long for through-hole PCB mounting.

Compact body size of 8.5mm diameter, 7.6mm height, and 7.37mm length for dense assembly. Breaking capacity of 35A ensures rapid clearing of fault conditions. Operates safely between -40°C and +125°C, suitable for harsh industrial environments.

Complies with IEC 60127-3, IEC 60068-2-20, and holds VDE, RoHS, and PSE approvals for standards compliance. Ideal for use in control panels, power supplies, transformers, and consumer electronic modules needing miniature fusing.
