- Reliable under demanding conditions: The design of the switch fuse contacts together with the fuse enables quick troubleshooting. The knife-type contacts are self-cleaning and maintenance-free.
- Easy to install: Thanks to the modular structure, the mechanism and poles can be positioned according to installation requirements. The length of the shaft can be adjusted, saving installation time and double cabling is possible without problems.
- Safety and Security: The locking of the fuse covers prevents their opening when the switch is in on-position. The fuses are completely isolated at each end when the switch is in off-position.
- Save time: With the type 2 online coordination tables, you can quickly find the equipment you are looking for motor protection. Various installation options, a modular frame and a wide selection of accessories make planning effortless.
