Why Choose the Wöhner 31941 Fuse Holder with Pilot Switch?
The Wöhner 31941 is a professional three-pole cylindrical fuse holder with an integrated pilot switch, designed for 14 × 51 mm cylindrical fuse links with a striker pin. As part of the Wöhner AMBUS® Panel range, it combines dependable circuit protection with remote fuse-status signalling, making it ideal for industrial machinery, automation systems and power distribution panels.
Rated at 50 A and 690 V AC, the integrated pilot switch is mechanically actuated by the striker pin of a compatible fuse link when it operates. This allows the fuse condition to be transmitted to an alarm, PLC or monitoring system, reducing fault-finding time and improving equipment availability.
Designed for DIN rail mounting, the Wöhner 31941 features secure terminals, a wide clamping range and an integrated label holder for clear circuit identification, making it an excellent choice for OEM machinery, industrial control panels and switchgear assemblies.

Reliable Circuit Protection with Remote Monitoring
The Wöhner 31941 accommodates three compatible 14 × 51 mm fuse links and provides dependable overcurrent protection for industrial electrical systems. When a fuse link fitted with a striker pin operates, the integrated pilot switch changes state, allowing the fault to be communicated directly to monitoring equipment or machine control systems.
This arrangement enables faster fault diagnosis, reduces maintenance time and supports improved uptime for critical industrial processes, making it particularly suitable for automated production environments.
Typical Applications
- Industrial control panels.
- Three-phase machinery.
- Motor protection circuits.
- OEM electrical equipment.
- Industrial automation systems.
- Switchgear and power distribution.
