FRS-R-6 - 6Amp Fuse

FRS-R-6 - 6Amp Fuse

The Eaton Bussmann FRS‑R‑6 6 Amp dual‑element time‑delay fuse delivers dependable, industrial‑level protection for critical electrical circuits subject to surges, spikes, or sustained fault conditions. With ratings of 600 Vac / 300 Vdc and an exceptionally high interrupting capacity—200 kA at 600 V AC and 20 kA at 300 V DC—this fuse gives you the confidence that your equipment and processes stay safeguarded even under heavy‑duty conditions. Thanks to its time‑delay design (10 seconds at 500% of rated current), the FRS‑R‑6 allows harmless inrush currents from motors or inductive loads to pass without nuisance trips, while quickly responding when true overloads or short‑circuit events occur. Whether you’re protecting lighting systems, motor control centres or conveyor feeds, this fuse offers high‑performance current limiting, efficient thermal behaviour and long‑term reliability in demanding environments.

Key Features and Benefits

• Dual‑Element Time‑Delay Protection – Allows temporary overloads from motor starts or equipment surges without sacrificing fault protection.
• Advanced Current Limiting – Significantly reduces the amount of energy let‑through in fault conditions, lowering damage risk to downstream components.
• High Interrupting Capacity – Rated at 200 kA at 600 Vac and 20 kA at 300 Vdc, giving strong fault tolerance in industrial applications.
• Efficient Thermal Performance – Designed to run cooler than conventional fuses, reducing stress on adjacent devices and helping prolong system life.
• Close Sizing Capability – The time‑delay feature permits sizing closer to actual load, enabling use of smaller carriers, panels, or switches and reducing overall system cost.

• Construction: Dual‑element, current‑limiting time‑delay design provides both overload and short‑circuit protection in one unit.

Where It Works Best

• Motor control centres, including large HVAC systems, fans, and pumps — the time‑delay function handles startup inrush without nuisance tripping.
• Lighting circuits, conveyor belts or industrial machinery where fault suppression and energy‑let‑through minimization are important.
• Panelboards, disconnects, or switchgear where Class RK5 fuse size and high interrupt rating allow for close‑fuse sizing and cost savings.
• Environments with mixed AC/DC loads (up to 300 Vdc) — thanks to the 300 Vdc rating this fuse provides flexibility.
• Facilities seeking to extend system life and reduce downtime by using a fuse that runs cooler and limits downstream damage.
