Motorized Switch Fuses

ABB offers a full range of motorized switch fuses. Motorized switch fuses (type OSM_) are suitable for remote control. The switch fuses can be operated either electrically by using the motor operator or manually by using the handle. The operation, either electrical or manual, can be chosen by the selector switch “Motor/Manual” on the motor operator. Motorized switch fuses consist of the switch fuse (type OS) and the motor operator. The motorized switch fuses are available for DIN, BS and NFC types of fuse links. The OSM range is for 32...1250 Amperes.

Designed for safety
The motorized switch fuses OSM ensure safe operation, protecting both people and equipment.

Designed and based on substantial experience of electrical safety, the switches eliminate the risk of electrical accidents
- In OSM motorized switch fuses the fuse covers cannot be opened while the switch fuse is in the ON-position and can be sealed in the closed position.
- The frames are made of robust plastic with excellent mechanical and thermal properties.
- Voltage output pins as standard
- Pole markings as standard
Inbuilt safety – eliminating the risk for accidents.

Easy, flexible installation
The motorized switch fuses OSM offer you flexible cabling options. The high terminal positioning with space to the back plate simplifies the mounting of cables.
It’s also ideal for double cabling, which in turn saves on space.
Reduced installation time reduces cost.

Suitable for remote locations - Connectivity to automation system
OSM motorized switch fuses can be operated remotely by using a suitable device e.g. push-buttons or a cam switch.
It is also easy to control the motor operator for example with PLC or PC-based controller.
Increased productivity .

High electrical ratings
- High Ui ratings
- High CTI in supporting parts
- The powerful construction in motorized swich fuses OSM, with their quick-make and quick-break operation features and two contact points instead of one
- In motorized switch fuses type OSM the contact constructions are optimal, regardless of fuse type, DIN, BS or NFC-type. High performance level and smart design makes OSM motorized switch fuses suitable for all applications in low voltage networks.
Suitable for numerous applications.
