MERSEN FERRAZ TRS40R Fuse, Time Delay, 40 A, 600V AC

Mersen Ferraz TRS40R fuse protects electrical circuits and equipment from overcurrent conditions and utilised in places where electrical systems face the risk of overload or short circuits.

Working Mechanism:

• It operates by allowing normal electrical current flow but swiftly responding to overcurrents or faults. It limits peak current levels during faults, preventing damage to connected equipment.
• Its time-delay brief current surges during startup without tripping. High-grade silica filler inside the fuse rapidly extinguishes any arcs formed during faults for safety.

Features:

• Mersen Ferraz TRS40R fuse features an optional solid-state SmartSpot blown fuse indicator and comes with time-delay functionality, ideal for accommodating motor start-ups and transformer inrush currents without unnecessary circuit interruptions.
• This fuse offers current-limiting capabilities, minimising peak let-thru current levels to safeguard equipment from destructive overcurrents.
• It is equipped with a rejection-style design, ensuring compatibility when used with recommended fuse blocks, reducing the risk of incorrect replacements.
• This fuse is designed with an easy-to-read label, facilitating quick brand recognition and hassle-free replacement during maintenance.
• It boasts a metal-embossed date and catalogue number, enhancing traceability and long-term identification for quality control and maintenance tracking.

Frequently Asked Questions:

Q. What is the benefit of using time-delay fuse?

A. Time-delay fuses can withstand temporary overcurrents during motor start-ups and transformer inrush currents without tripping, ensuring smooth equipment operation.

Q. What is the SmartSpot blown fuse indicator and how does it work?

A. The SmartSpot indicator provides a visual signal when the fuse has blown, making it easier to identify faulty circuits. It works by changing colour or displaying a symbol.
