The Mersen J300112 is a Protistor® Size 30 square body high-speed semiconductor fuse engineered to provide advanced protection for modern power electronic equipment. Featuring an aR ultra-fast operating characteristic, it protects sensitive semiconductor devices including IGBTs, thyristors, diodes and MOSFETs from damaging short-circuit currents while helping maximise equipment reliability and minimise downtime.
Manufactured by Mersen, the J300112 carries catalogue number PC30UD69V160A and forms part of the trusted Protistor® Size 30 range. It is rated at 160 A with a 690 V AC IEC / 700 V AC UL voltage rating and features DIN 80 blade terminals with an integrated striker indicator for easy status monitoring and maintenance.
Its ceramic square body construction, silver-plated contacts and high 200 kA AC breaking capacity make the J300112 ideal for demanding industrial power conversion applications including variable frequency drives, UPS systems, converters, soft starters and renewable energy installations.
High-speed semiconductor fuses are specifically designed to interrupt fault currents before they can damage expensive power electronic components. Their ultra-fast response and low let-through energy help improve equipment availability while reducing repair costs and unplanned downtime.
The Mersen Protistor® range is trusted worldwide by OEMs, panel builders and maintenance engineers for protecting industrial drives, converters, UPS systems and renewable energy equipment operating in demanding environments.
