Reliable Four-Pole Switching for ABB OS250 Equipment
A switched fourth pole enables an additional conductor to be switched together with the three primary poles of compatible switching equipment. This configuration is commonly required where the electrical system or installation design calls for simultaneous four-pole isolation or switching.
The ABB OSP250N is engineered specifically for compatible OS250 equipment, providing a manufacturer-matched accessory rather than a general-purpose switching component. Its left- or right-side mounting capability also gives panel builders and electrical engineers flexibility when configuring switch fuse assemblies.
Typical Applications
- Four-pole ABB OS250 switch fuse configurations.
- Low-voltage electrical distribution systems.
- Industrial control panels and switchboards.
- Machinery electrical isolation systems.
- Power distribution and control assemblies.
- OEM electrical panel building and system integration.
