Why Choose the ABB ZLSP251 Feeder Component?
The ABB ZLSP251 is a 250 A L1 feeder component designed for incoming phase connections within the ABB SMISSLINE TP Power Bar system. It provides a dedicated L1 connection to the busbar system and forms part of ABB's modular incoming terminal range for high-current commercial and industrial power distribution assemblies.
Rated at 250 A, the ZLSP251 provides flexible conductor termination for substantial incoming supplies. It accepts one flexible conductor from 50–120 mm² when fitted with a ferrule, or two conductors from 10–25 mm² with ferrules, allowing the incoming connection arrangement to be matched to the installation requirements.
The ZLSP251 occupies just 2 modules and measures 36 × 50 × 68 mm, providing a compact connection solution for high-current distribution systems. It can be combined with the corresponding ZLSP250 neutral, ZLSP252 L2 and ZLSP253 L3 feeder components to create a complete incoming supply arrangement for the SMISSLINE TP Power Bar system.

High-Current Incoming Power Distribution for SMISSLINE TP
Incoming feeder components provide the electrical interface between external supply conductors and the SMISSLINE TP busbar system. The ABB ZLSP251 is specifically configured for the L1 phase conductor, providing a compact and purpose-designed incoming connection for high-current SMISSLINE TP Power Bar assemblies.
The modular feeder concept allows the ZLSP251 L1 component to be combined with the ZLSP250 for neutral, ZLSP252 for L2 and ZLSP253 for L3. This arrangement enables individual feeder components to be configured around the required supply architecture while providing conductor capacity suitable for substantial commercial and industrial electrical distribution installations.
