2CCA183442R0001 ABB ZLS927 Additional Socket Insulator Block

Why Choose the ABB ZLS927 Insulator Block?

The ABB ZLS927 is a dark grey insulator block for additional sockets in the ABB SMISSLINE TP plug-in system. Designed specifically for the modular SMISSLINE architecture, it provides a simple and clearly identifiable means of electrically separating interrupted busbar sections within a distribution assembly.

The ZLS927 is used to isolate the N busbar on an additional socket. By separating the interrupted busbar ends from one another, the insulator block establishes a defined electrical disconnection while its dark grey appearance simultaneously provides an external visual indication of the separation point.

Occupying only 0.5 module and weighing approximately 9 g, the ZLS927 integrates neatly into compatible SMISSLINE TP additional socket arrangements. It is a purpose-designed ABB accessory for applications where neutral busbar sections need to be divided while retaining the organised, modular construction of the SMISSLINE system.

Key Advantages

• Purpose-designed insulator block for ABB SMISSLINE TP additional sockets.
• Electrically isolates interrupted N busbar sections from one another.
• Provides a clearly visible external indication of the busbar disconnection point.
• Compact 0.5-module format minimises space requirements.
• Dark grey construction makes the isolation point readily identifiable.
• Integrates directly with the modular ABB SMISSLINE TP distribution architecture.

Key Features

• ABB SMISSLINE TP Plug-in System accessory.
• Designed as an insulator / isolator block.
• For use with SMISSLINE TP additional sockets.
• Designed to isolate the neutral (N) busbar.
• Separates interrupted busbar ends from one another.
• Externally identifies the defined disconnection point.
• Dark grey construction.
• Compact 0.5-module size.

Defined Busbar Isolation for SMISSLINE TP

The ABB SMISSLINE TP system supports modular electrical distribution using plug-in socket bases, busbars and dedicated system accessories. Where an N busbar on an additional socket must be interrupted, the ZLS927 provides the purpose-designed insulation needed to keep the separated busbar ends electrically isolated.

In addition to providing electrical separation, the dark grey ZLS927 marks the disconnection point externally. This combination of functional isolation and clear identification supports organised SMISSLINE TP assemblies where individual neutral busbar sections need to be separated within the distribution system.

Typical Applications

• ABB SMISSLINE TP plug-in distribution systems.
• Neutral busbar isolation on additional sockets.
• Creation of electrically separated N busbar sections.
• Low-voltage electrical distribution boards.
• Industrial control and automation panels.
• Modular commercial and infrastructure distribution assemblies.
