Why Choose the ABB ZLS924-3L Incoming Terminal Block?
The ABB ZLS924-3L is a 3-phase left-hand incoming terminal block designed for the ABB SMISSLINE TP plug-in distribution system. Supplied under ABB order code 2CCF181816R0001, it provides incoming connections for the L1, L2 and L3 busbars and is suitable for use with compatible 125 A and 250 A SMISSLINE TP systems.
The ZLS924-3L uses a 4-module, 72 mm-wide format and is designed for side-feed applications. ABB specifies the ZLS924 incoming terminal block family for 125 A side feed or 160 A centre feed, providing a flexible means of supplying SMISSLINE TP busbars in professional distribution assemblies.
This version is configured as 3L left and is supplied with its cover. The phase terminals support conductor capacities up to 50 mm² (2 × 25 mm²), providing a substantial incoming connection while maintaining the modular construction of the SMISSLINE TP system.

Flexible Plug-in Power Distribution
ABB SMISSLINE TP uses modular sockets, busbars and incoming terminal components to provide a flexible platform for electrical power distribution. The ZLS924 family provides incoming connections for the main phase and optional neutral and auxiliary busbars, with left- and right-hand variants available to suit different panel configurations.
The ZLS924-3L is the left-hand three-phase version, providing connections for L1, L2 and L3. Left- and right-hand incoming blocks can be selected according to the layout of the distribution assembly, helping reduce unnecessary cable crossing when multiple SMISSLINE TP socket rows are supplied.
Typical Applications
- ABB SMISSLINE TP modular distribution systems.
- Three-phase L1, L2 and L3 incoming supply connections.
- 125 A side-fed SMISSLINE TP distribution assemblies.
- Compatible centre-fed distribution arrangements up to 160 A.
- Commercial and industrial electrical distribution boards.
- Control and automation panels requiring modular three-phase power distribution.
