Why Choose the ABB OTZ1600E Fourth Pole?
The ABB OTZ1600E is a dedicated fourth-pole accessory designed for the ABB OT1600E switch-disconnector. It provides an additional switched pole for applications where a compatible three-pole OT1600E needs to be extended to a four-pole switching arrangement.
The OTZ1600E mounts on the side of the three-pole switch and is intended for installations without wide phase distances. Its switching action operates simultaneously with the main contacts, ensuring the additional conductor is switched together with the three main poles.
As an original ABB switch-disconnector accessory, the OTZ1600E provides purpose-designed mechanical compatibility with the OT1600E platform. With compact dimensions of approximately 372 × 80 × 131.5 mm and a unit weight of approximately 4.54 kg, it provides a straightforward solution for creating a coordinated four-pole high-current switching assembly.
Key Advantages
- Genuine ABB fourth-pole accessory for the OT1600E switch-disconnector.
- Converts a compatible three-pole OT1600E into a four-pole switching arrangement.
- Additional pole operates simultaneously with the main contacts.
- Mounts directly on the side of the compatible three-pole switch.
- Designed for switches without wide phase distances.
- Purpose-designed for mechanical integration with the ABB OT platform.
- Avoids the need for a separately operated additional switching device.
- Suitable for demanding high-current switchboard and distribution applications.
Key Features
- ABB OTZ1600E fourth pole.
- ABB order code 1SCA100431R1001.
- Additional-pole accessory for switch-disconnectors.
- Designed specifically for ABB OT1600E.
- Used with a compatible three-pole switch-disconnector.
- Simultaneous operation with the main switch contacts.
- Side-mounted installation.
- Suitable for configurations without wide phase distances.
- Approximate unit weight of 4.54 kg.
- Compact additional-pole construction for high-current switching assemblies.
Additional Pole for ABB OT1600E Switch-Disconnectors
A fourth-pole accessory allows an additional conductor to be switched at the same time as the three main poles of a switch-disconnector. This is useful in installations where the electrical design requires four conductors to be isolated simultaneously rather than leaving the additional conductor permanently connected.
The ABB OTZ1600E is engineered specifically for the OT1600E platform and mechanically follows the operation of the main switch contacts. Its side-mounted construction creates an integrated four-pole assembly while retaining the operating characteristics and installation concept of the compatible ABB OT switch-disconnector.
Typical Applications
- ABB OT1600E switch-disconnector installations.
- Four-pole high-current switching configurations.
- Industrial switchboards and distribution panels.
- Main incoming electrical isolation.
- Three-phase systems requiring an additional switched conductor.
- Industrial power distribution assemblies.
- OEM switchgear and electrical equipment.
