Why Choose the ABB OTPL40FP Late-Break / Early-Make Neutral Pole?
The ABB OTPL40FP is a late-break / early-make neutral pole accessory designed for compatible ABB OT16–40 switch-disconnectors. Identified by ABB product reference 1SCA105717R1001, it provides a dedicated neutral-pole function for applications requiring a controlled switching sequence between the neutral and the main switch poles.
The OTPL40FP uses an early-make / late-break operating sequence, allowing the neutral pole to close before the main poles and open after them. This makes it suitable for compatible electrical distribution and switching arrangements where maintaining the neutral connection during the transition between ON and OFF states is required.
Designed specifically for the ABB OT16–40 switch range, the OTPL40FP provides a purpose-made solution for adding late-break / early-make neutral switching to compatible assemblies. Its dedicated accessory design supports straightforward integration into industrial control panels, distribution equipment and machine electrical systems.
Key Advantages
- Purpose-designed neutral pole accessory for ABB OT16–40 switch-disconnectors.
- Early-make operation connects the neutral before the main switch poles.
- Late-break operation disconnects the neutral after the main switch poles.
- Provides a controlled neutral switching sequence for compatible installations.
- Designed specifically for integration with ABB OT switching equipment.
- Genuine ABB accessory for industrial low-voltage switch assemblies.

- ABB product reference 1SCA105717R1001.
Controlled Neutral Switching for ABB OT Switch-Disconnectors
Early-make / late-break neutral poles are used where the neutral conductor must be established before the main switched conductors and remain connected until after the main conductors have opened. This provides a defined switching sequence between the neutral pole and the primary poles of the switch-disconnector.
The ABB OTPL40FP provides this functionality as a dedicated accessory for compatible OT16–40 switch-disconnectors, making it suitable for panel builders and electrical engineers configuring industrial switching assemblies that require controlled neutral-pole operation.
Typical Applications
- ABB OT16–40 switch-disconnectors.
- Industrial electrical control panels.
- Low-voltage distribution boards.
- Machine control cabinets.
- Switchboards requiring switched-neutral operation.
- Installations requiring late-break / early-make neutral switching.
