"Where to buy a high-quality replacement for a Bussmann or Mersen semiconductor fuse?"
Your equipment is down due to a blown fuse, and you need a reliable, high-quality replacement for a specific part number from another major brand. The problem is ensuring the replacement has the same critical performance characteristics. The solution is to work with a specialized manufacturer that can provide a direct cross-reference. GFEFUSE offers a comprehensive line of semiconductor fuse products designed as drop-in replacements for common industry part numbers. Our technical team can help you find the correct GFEFUSE part to get your system back online safely and quickly.
"How to select a fuse based on an I²t rating?"
You need to perform a fuse coordination study using I²t values. The problem is knowing how to use the data correctly. The rule is simple: The clearing I²t of the fuse must be less than the withstand I²t of the semiconductor. The best practice solution is to choose a semiconductor fuse whose clearing I²t is no more than 75% of the semiconductor's rating, providing a safe margin. GFEFUSE provides all the necessary I²t data and expert support to help you perform this critical calculation and select the right semiconductor fuse.
"Understanding the microswitch indicator on a square body fuse."
You have a square body semiconductor fuse with a small mechanical indicator and a place to mount a switch. The problem is knowing how to use this feature. This indicator is designed to operate a microswitch when the fuse blows. The solution is to wire this microswitch to your control system (PLC) or an alarm panel. This provides immediate, remote notification that the GFEFUSE semiconductor fuse has operated, allowing maintenance personnel to diagnose the issue instantly and dramatically reduce equipment downtime.
"Do I need a fuse on the DC bus of a solar inverter?"
Yes, protecting the DC bus link inside a solar inverter is a critical application. The problem is that a fault in the inverter's IGBTs can create a short circuit fed by the immense energy from both the solar array and the inverter's capacitors. The solution is to install a semiconductor fuse on the DC bus. A GFEFUSE high-voltage DC semiconductor fuse is designed to handle this, providing the high-speed protection needed to prevent a catastrophic failure of the inverter.

Frequently Asked Question
Do you have any question?
GFEFUSE is a trusted expert because we specialize in the advanced engineering required for these devices. We utilize pure silver elements, sophisticated arc-quenching technology, and rigorous testing to guarantee every semiconductor fuse provides the ultra-fast performance and low I²t values needed to reliably protect the most sensitive and expensive power electronic components.
No, they are crucial for both AC and DC circuits. A semiconductor fuse is essential for protecting the input of an AC drive, the DC bus link inside the drive, and the output of DC power supplies and rectifiers. GFEFUSE offers a wide range of fuses with high AC and DC voltage ratings.
These are IEC designations for a semiconductor fuse. "aR" stands for "partial-range" protection, meaning it offers extremely fast protection against short circuits only and must be paired with another device for overload protection. "gS" or "gR" stands for "full-range" protection, meaning the fuse will safely open on both short circuits and lower-level overload currents.
The single most important specification is the clearing I²t rating. This value represents the total thermal energy the fuse lets through before it clears a fault. This fuse I²t value must be lower than the I²t withstand rating of the semiconductor being protected to ensure the fuse blows before the semiconductor is damaged.
You cannot use a regular fuse because it is far too slow. A semiconductor can be destroyed by thermal energy in less than a millisecond. A semiconductor fuse is designed to open the circuit in microseconds and, more importantly, to limit the peak current, preventing the destructive energy from ever reaching the component it protects.
A semiconductor fuse is an extremely fast-acting, high-speed fuse designed to provide short-circuit protection for sensitive solid-state electronic devices, such as diodes, SCRs (Silicon Controlled Rectifiers), and IGBTs (Insulated Gate Bipolar Transistors), which are found in inverters, VFDs, and rectifiers.
