What types of fuses does Mersen manufacture?

Mersen manufactures a comprehensive range of electrical protection devices: 1) High-Speed Fuses - Ultra-fast acting fuses for semiconductor protection in power electronics, featuring low I2t values and high breaking capacity

2) DC Fuses - High-voltage DC fuses for electric vehicles (up to 1000VDC), energy storage systems (up to 1500VDC), and solar applications

3) Industrial Fuses - Power and distribution fuses for industrial applications including motor protection and power distribution

4) Surge Protection Devices - SPDs for protecting electrical equipment from voltage surges and lightning strikes. All products comply with international standards including UL, IEC, and CE.

Browse our product categories to find the right Mersen protection device for your application.

How do Mersen high-speed fuses protect semiconductors?

Mersen high-speed fuses are specifically designed to protect power semiconductors (IGBTs, diodes, thyristors) from overcurrent damage. Key features include: 1) Ultra-fast acting - Opens within milliseconds to limit let-through energy (I2t)

2) Low I2t values - Minimizes thermal stress on protected semiconductors

3) Current limitation - Reduces peak fault current to safe levels

4) High breaking capacity - Safely interrupts high fault currents up to 200kA

5) Arc voltage control - Limits arc voltage to protect semiconductor junctions. The fuse acts faster than the semiconductor's thermal time constant, preventing device destruction during short circuits.

Use Mersen high-speed fuses for all semiconductor protection applications. Contact our FAE for fuse selection based on your semiconductor ratings.

What is the difference between Mersen high-speed fuses and standard fuses?

Mersen high-speed fuses differ from standard fuses in several critical aspects: 1) Opening speed - High-speed fuses open in <1ms vs 10-100ms for standard fuses

2) I2t let-through - High-speed fuses have much lower I2t values to protect semiconductors

3) Current limitation - High-speed fuses actively limit peak fault current

4) Arc voltage - Controlled arc voltage to protect semiconductor junctions

5) Breaking capacity - Higher breaking capacity (up to 200kA) for power electronics

6) Applications - High-speed for semiconductors, standard for general circuit protection. Standard fuses are too slow to protect expensive semiconductors.

Use high-speed fuses for semiconductor protection. Use standard/industrial fuses for general circuit protection.

How do I select the right Mersen fuse for my application?

Selecting the right Mersen fuse involves several key steps: 1) Identify application type - semiconductor protection, DC power, or general industrial

2) Determine voltage rating - must exceed maximum system voltage including transients

3) Calculate current rating - typically 1.25x to 1.5x normal operating current

4) Verify breaking capacity - must exceed maximum prospective fault current

5) For semiconductors - match fuse I2t to semiconductor withstand capability

6) Consider physical size and mounting type

7) Check certification requirements for your market. BeiLuo provides selection guides and FAE support to help you choose the optimal fuse.
