Product Description

Eaton SR-5-315MA-BK is a radial leaded time delay fuse designed for sensitive low-current and control circuits operating at 250V AC. This precision fuse tolerates transient surges without tripping unnecessarily, making it ideal for applications requiring reliable protection without interruption from harmless spikes.

The fuse features a radial lead design with a conductor diameter of 1mm and a lead length of 4.3mm, allowing straightforward PCB through-hole mounting. Its compact subminiature body measures 8.5mm in diameter and 7.6mm in height, suited to installations with limited space.

Operating reliably across a wide temperature range from -40°C to +125°C, this fuse ensures performance in harsh industrial, automation, and electronic equipment environments. With a breaking capacity of 35A, it safely interrupts fault conditions involving elevated short-circuit currents.

Approved to multiple international safety and quality standards including IEC 60127-3 and VDE, the Eaton SR5 series fuse supports system designs compliant with global regulatory requirements. Typical applications include protection of instrument power inputs, control panels in automation systems, and consumer electronic devices needing slow-blow fuse characteristics.

This fuse provides precise overcurrent protection for sensitive electronic circuits. The time-delay characteristic prevents nuisance tripping from transient surges. Radial lead format facilitates easy PCB mounting and assembly.

Compact size suits installations with limited space availability. Wide operating temperature range ensures reliable function under varied environmental conditions. High breaking capacity protects against severe short-circuits safely.

Compliance with major international standards ensures application versatility. Explore Eaton Fuse products and similar circuit protection components within the Electronics & Electricals category at EnvMart.
