Why Choose the Mersen HSJ60 High Speed Class J Fuse?
The Mersen HSJ60 is a high-performance Class J high speed semiconductor fuse designed to provide dependable branch circuit protection alongside rapid protection for sensitive power semiconductor devices. Part of the established Mersen Amp-Trap® HSJ Series, it combines low let-through energy with Class J circuit protection, making it suitable for demanding industrial automation, motor control and power conversion applications.
Engineered to clear damaging fault currents quickly, the HSJ60 helps protect diodes, SCRs, GTOs, IGBTs, solid state relays and other semiconductor components. Its high speed operating characteristic limits the thermal and electrical energy reaching protected equipment, helping reduce component damage, maintenance costs and unplanned production downtime.
With a rated current of 60 A, an AC voltage rating of 600 V and a DC voltage rating of 500 V, the Mersen HSJ60 is well suited to variable frequency drives, soft starters, industrial control panels and electronic power equipment. Its compact ferrule construction enables secure clip mounting in compatible Class J fuse holders.

Reliable Protection for Industrial Power Electronics
The Mersen HSJ60 is designed to interrupt short-circuit currents before excessive fault energy can damage sensitive semiconductor components. By limiting peak current and let-through energy, the fuse helps protect electronic switching devices that are often more vulnerable to overcurrent conditions than conventional electrical equipment.
Combining Class J branch circuit performance with high speed semiconductor protection can help simplify electrical panel design. The HSJ60 is particularly suitable for motor drives, power conversion systems and electronically controlled industrial machinery requiring coordinated overcurrent protection.
