Product Model
OS125GF03
Selling Points
- 1Designed for extreme conditions to ensure reliable operation in heavy industry applications.
- 2Knife contact design keeps contacts pushed firmly together before, during, and after a fault without damaging the switch.
- 3Easy and cost-efficient installation, maintenance, and use with adjustable shafts and snap-on auxiliary contacts.
- 4Interlocking fuse covers prevent opening while the switch is in “ON” position, reducing the risk of electric shock.
- 5Rated for 125A with a dielectric strength of 10kV and impulse withstand voltage of 12kV, ensuring high performance in demanding applications.
