Why Choose the ABB OT800U02 800 A 2-Pole Switch-Disconnector?
The ABB OT800U02 is a heavy-duty 800 A two-pole non-fusible switch-disconnector designed for dependable manual switching and electrical isolation in high-current industrial power distribution systems. Identified by ABB product ID 1SCA112977R1001, it forms part of the OT800U switch-disconnector range.
The OT800U02 features a two-pole, front-operated configuration with its operating mechanism positioned at the left-hand end of the switch. It is designed for base mounting and uses lug terminals, making it suitable for integration into substantial switchboards, control panels and power distribution assemblies.
This version is supplied without a handle and shaft, so the appropriate ABB operating accessories must be ordered separately. The OT800U02 carries an 800 A UL/CSA ampere rating, supports main-circuit operational voltages up to 1000 V, and provides a rated short-time withstand current of 50 kA for 1 s.
Key Advantages
- Heavy-duty 800 A two-pole switch-disconnector.
- UL/CSA ampere rating of 800 A.
- Non-fusible construction for straightforward manual isolation.
- Main-circuit operational voltage up to 1000 V.
- 50 kA short-time withstand current for 1 s.
- Front-operated configuration with mechanism at the end of the switch.
- Base mounting supports robust switchboard integration.
- Handle and shaft ordered separately for installation flexibility.
Key Features
- ABB OT800U switch-disconnector range.
- 800 A fully enclosed thermal current.
- 2-pole configuration.
- Front-operated design.
- Left-side mechanism at the end of the switch.
- Base-mounted construction.
- Handle and shaft not included.
- Lug main-circuit terminals.
- Top-in / bottom-out or bottom-in / top-out terminal arrangement.
- 600 V maximum operating voltage under UL/CSA ratings.
- Complies with IEC 60947-3, UL 98 and CSA C22.2 No. 4.
High-Current Two-Pole Electrical Isolation
A two-pole switch-disconnector provides simultaneous manual switching and isolation of two conductors, creating a clearly defined disconnection point for high-current electrical equipment and distribution circuits. Non-fusible construction separates the switching and isolation function from any separately specified overcurrent protection.
The ABB OT800U02 combines an 800 A UL/CSA rating with substantial short-circuit withstand performance and a robust base-mounted arrangement. Because its handle and shaft are ordered separately, the operating arrangement can be selected to suit the enclosure and switchboard design while retaining the OT800U switching platform.
Typical Applications
- High-current two-pole electrical isolation.
- Industrial switchboards and distribution assemblies.
- Machinery and process equipment isolation.
- Commercial and industrial power distribution.
- Control panels requiring a non-fusible disconnecting means.
- UL/CSA industrial electrical installations.
