The Siemens 3NE32320B SITOR Semiconductor Fuse is a high-performance fuse link specifically designed to protect sensitive semiconductor devices and power electronic systems from damaging short-circuit currents. As part of the globally trusted Siemens SITOR 3NE3 series, the 3NE32320B delivers ultra-fast fault interruption, making it ideal for applications where conventional fuses cannot provide adequate protection for expensive semiconductor components.
Rated at 400A and 1000V AC, the Siemens 3NE32320B is engineered to safeguard critical equipment such as variable frequency drives (VFDs), UPS systems, inverters, converters, rectifiers, soft starters, and industrial automation systems. The fuse features an aR characteristic, specifically developed for semiconductor protection, ensuring rapid disconnection during fault conditions while minimizing let-through energy to protected devices.
Available on SBSmart.in, the Siemens 3NE32320B combines German engineering excellence, superior reliability, and advanced protection technology, making it a preferred choice for OEMs, panel builders, industrial maintenance teams, electrical contractors, and system integrators.
Modern power electronic systems rely on sensitive semiconductor components such as IGBTs, thyristors, diodes, and SCRs. These devices can be severely damaged by fault currents within milliseconds. The Siemens 3NE32320B SITOR Fuse is specifically designed to react significantly faster than standard HRC fuses, protecting valuable equipment before damage occurs.
SITOR semiconductor fuses are recognized for their super-fast disconnection characteristics, making them ideal for protecting high-value power electronic systems against short-circuit faults.
The Siemens 3NE32320B is classified as an aR semiconductor protection fuse, meaning it is specifically designed to provide short-circuit protection for semiconductor devices. Unlike conventional gG fuses, aR fuses respond extremely quickly and help limit the energy reaching sensitive electronic components.
This makes the Siemens 3NE32320B an essential protection component in modern industrial power electronics systems.
The Siemens 3NE32320B is manufactured in an NH1 DIN fuse size with slotted blade contacts and front indication, ensuring compatibility with standard industrial fuse bases and switchgear assemblies.
