Why Choose the ABB ZLS973N300 Universal Adaptor?
The ABB ZLS973N300 is a single-pole 63 A neutral universal adaptor designed for the ABB SMISSLINE TP plug-in system. It provides a dedicated neutral connection with a 300 mm connecting wire positioned at the bottom, enabling compatible modular devices to be integrated into SMISSLINE distribution assemblies.
Rated for currents up to 63 A, the ZLS973N300 combines a compact one-module, 18 mm-wide format with an extended 300 mm neutral lead. The longer connection wire provides additional routing flexibility where the neutral terminal of the connected equipment is positioned away from the SMISSLINE plug-in connection point.
The ZLS973N300 forms part of ABB's comprehensive universal adaptor range for SMISSLINE TP 125 A and 250 A systems. Complementary phase and neutral adaptors are available with top or bottom wire orientations, allowing installers and panel builders to configure suitable single-pole and multi-pole arrangements.

63 A Neutral Connection with an Extended 300 mm Lead
ABB's universal adaptor system provides a practical method of incorporating compatible conventional modular equipment into SMISSLINE TP assemblies. The ZLS973N300 is specifically configured for the neutral conductor and combines a 63 A rating with a 300 mm bottom-positioned connecting wire. This extended lead is useful where additional conductor length is required to reach the neutral terminal of the installed device.
The wider ABB range includes corresponding 63 A L1/L2/L3 adaptors as well as neutral and phase versions with top-positioned wires. Individual universal adaptors can therefore be selected and combined according to the required pole arrangement, conductor function and cable-routing direction while maintaining a consistent SMISSLINE installation architecture.
Typical Applications
- ABB SMISSLINE TP plug-in distribution systems.
- SMISSLINE TP 125 A and 250 A installations.
- Neutral connections for compatible universal adaptor arrangements.
- Applications requiring an extended 300 mm neutral lead.
- Integration of compatible conventional DIN-rail equipment.
- Single-pole and multi-pole modular adaptor configurations.
- Commercial and industrial electrical distribution assemblies.
