MERSEN FUSE 6,9 URGL 36 P 200 6,9URGL36P200

Why Choose the Mersen N097187 High-Speed Semiconductor Fuse?

The Mersen N097187 is a dependable high-speed semiconductor fuse engineered to protect sensitive power electronic equipment against damaging short-circuit currents. Designed for industrial power conversion applications, this Mersen fuse combines rapid fault interruption with effective current limitation to help protect valuable semiconductor components.

The N097187 features an aR operating class, making it suitable for partial-range protection of semiconductor devices such as diodes, thyristors, rectifiers and IGBTs. Its high-speed performance helps minimise the thermal and mechanical energy transferred to protected equipment during a fault, reducing the likelihood of extensive component damage and unplanned downtime.

With a rated current of 200 A and a maximum rated voltage of 690 V AC, the Mersen N097187 is ideal for industrial drives, converters, inverters, UPS systems and power supplies. Its 36 × 55 mm BS-style cylindrical body and integrated striker provide practical installation and clear operation within compatible fuse holders and protection assemblies.

Reliable Protection for Industrial Power Electronics

High-speed fuses such as the Mersen N097187 interrupt dangerous fault currents much faster than conventional industrial fuse links. This rapid response limits the let-through energy reaching sensitive semiconductor components, helping protect power electronic assemblies from severe thermal and electrical damage.

The aR characteristic is specifically intended for short-circuit protection of semiconductor equipment. Suitable supplementary overload protection should therefore be incorporated into the electrical system where full-range protection is required.

Typical Applications

• Variable frequency drives and industrial motor controllers.
• Power converters and rectifier assemblies.
• Industrial inverters and power supplies.
• Uninterruptible power supply systems.
• Semiconductor-controlled heating equipment.
• Automation and power distribution panels.
