Why Choose the ABB OTPL125FP Late-Break / Early-Make Neutral Pole?
The ABB OTPL125FP is a purpose-designed late-break / early-make neutral pole for compatible ABB OT switch-disconnectors. Part of the ABB OT accessory range, it is specifically intended for the OT125E3 switch configuration and provides an additional neutral pole with sequenced operation.
The late-break / early-make operating principle keeps the neutral connected during the transition of the main switching poles, with the neutral designed to make before and break after the phase contacts. This arrangement is useful in switching applications where maintaining the neutral connection during the switching sequence is required.
Designed as a dedicated ABB accessory, the OTPL125FP integrates with the compatible OT125E3 switch-disconnector rather than relying on a generic additional pole. It is suited to industrial distribution panels, control cabinets and isolation assemblies requiring a coordinated switched-neutral arrangement.

Sequenced Neutral Switching for ABB OT Assemblies
A late-break / early-make neutral pole is designed so that the neutral connection is established before the principal switched conductors and remains connected until after they disconnect. This sequencing can provide the required neutral continuity during the switching transition in electrical systems designed for switched-neutral operation.
The ABB OTPL125FP provides this function as a dedicated accessory for the OT125E3 switch configuration. Its manufacturer-matched design makes it suitable for panel builders and electrical engineers creating coordinated ABB OT switching and isolation assemblies.
Typical Applications

- Industrial electrical distribution panels.
- Switched-neutral isolation systems.
- Electrical control and automation cabinets.
- Machinery power isolation assemblies.
- Switchboards requiring early-make / late-break neutral operation.
