Why Choose the ABB OTZ800E Fourth Pole for OT630–800E Switch Disconnectors?
The ABB OTZ800E, order code 1SCA022807R5100, is a genuine ABB fourth-pole accessory designed for compatible OT630E through OT800E manual switch disconnectors. It allows a compatible 3-pole switch to be extended to a 4-pole configuration without replacing the complete switching device.
The OTZ800E features simultaneous operation with the main contacts. Once fitted, the additional pole is mechanically coordinated with the main switch so that it opens and closes together with the original three poles, providing a complete four-pole switching arrangement for applications requiring an additional switched conductor.
Designed for straightforward integration, the OTZ800E mounts on the side of the 3-pole switch without requiring wide phase distances. Its purpose-designed construction ensures compatibility with the ABB OT630–800E platform, making it a practical accessory for switchboards, distribution panels and industrial isolation systems.
Key Advantages
- Adds a fourth switched pole to compatible ABB OT630–800E switch disconnectors.
- Provides simultaneous operation with the three main contacts.
- Allows a compatible 3-pole switch disconnector to be converted to a 4-pole arrangement.
- Mounts directly on the side of the switch.
- Does not require wide phase distances for installation.
- Mechanically coordinated with the main switching mechanism.
- Designed specifically for the ABB OT630E and OT800E IEC switch-disconnector platform.
- Genuine ABB accessory for reliable mechanical compatibility and integration.
Key Features
- ABB OTZ fourth-pole accessory series.
- Dedicated fourth pole for OT630–800E switch disconnectors.
- 1-pole accessory for extending a compatible 3-pole switch.
- Simultaneous switching function with the main contacts.
- Side-mounted configuration.
- No wide phase distance required.
- Mechanically operated by the main switch mechanism.
- Designed for ABB manual OT switch disconnectors.
- Suitable for IEC OT630E and OT800E switch-disconnector configurations.
- Compact accessory construction.

- Supplied as one fourth-pole accessory.
How Does the OTZ800E Simultaneous Fourth Pole Work?
The ABB OTZ800E is mechanically linked to a compatible OT630–800E 3-pole switch disconnector. Unlike late-break or early-make neutral-pole accessories, the OTZ800E is designed for simultaneous operation, meaning its contact follows the switching action of the three main contacts when the switch is opened or closed.
This arrangement provides a straightforward method of creating a four-pole switch-disconnector configuration from a compatible three-pole ABB OT device. Because the fourth pole mounts directly on the side without requiring wide phase distances, it can be integrated efficiently into suitable switchboards and electrical distribution assemblies.
Typical Applications
- Adding a fourth pole to compatible ABB OT630E switch disconnectors.
- Adding a fourth pole to compatible ABB OT800E switch disconnectors.
- Four-pole electrical isolation systems.
- Three-phase and neutral distribution arrangements requiring simultaneous switching.
- Industrial low-voltage switchboards.
- Commercial electrical distribution panels.
- Machinery and equipment isolation systems.
- OEM switchgear and power-distribution assemblies.
