Why Choose the ABB OTZT2A Mechanical Interlock Kit?
The ABB OTZT2A is a purpose-designed mechanical interlock kit for compatible ABB OT switch-disconnectors. Part of the ABB OT/OETL accessory range, it is specified for OT315…400 switches and enables the switch mechanism to be mechanically interlocked in the OFF position.
The OTZT2A mounts directly to the switch operating mechanism and provides a dedicated means of preventing operation from the isolated OFF state when the interlock is engaged. This supports controlled isolation procedures in industrial switchboards, machinery panels and electrical distribution assemblies using compatible ABB OT switches.
ABB specifies the OTZT2A for the OT315…400 range, with compatible catalogue configurations including OT400U and OT315…400E. The interlock has approximate dimensions of 52 × 152 × 102 mm (W × H × D), a net weight of approximately 0.57 kg, and supports a lock bail diameter of up to 8 mm.

Mechanical OFF-Position Interlocking for ABB OT Switches
Mechanical interlocking provides a physical means of securing the operating mechanism against switching from its isolated state. The ABB OTZT2A is specifically designed to interlock compatible OT315…400 switch-disconnectors in the OFF position, helping maintain the selected isolation state during authorised maintenance and operational procedures.
The interlock kit is mounted on the switch mechanism and can be used with a locking device having a bail diameter of up to 8 mm. Its manufacturer-matched design makes the OTZT2A suitable for panel builders and electrical engineers configuring ABB OT switching assemblies where positive OFF-position interlocking is required.
Typical Applications
- ABB OT315…400 switch-disconnector assemblies.
- Industrial switchboard isolation systems.
- Machinery power isolation equipment.
- Electrical distribution panels.
- Control and automation cabinets.
- Installations requiring mechanical interlocking of the switch in the OFF position.
