Why Choose the ABB OTZT2L Mechanical Interlock Kit?
The ABB OTZT2L is a purpose-designed mechanical interlock kit for compatible ABB OT/OS switch-disconnector applications. Part of the ABB OT/OETL accessory range, it is specified for the OT/OS315–400 class and provides mechanical interlocking in both the OFF and ON positions.
The OTZT2L is designed to mount at the switching mechanism, providing a dedicated mechanical locking arrangement for applications where the operating state must be secured against unintended movement. Unlike an OFF-only interlock, the OTZT2L is specifically configured for OFF- and ON-position interlocking, making it suitable for installations requiring controlled retention of either operating state.
ABB identifies OTZT2L as product main type OTZT2. The accessory has approximate dimensions of 52 × 152 × 102 mm (W × H × D), a net weight of approximately 0.57 kg, and supports locking arrangements with a maximum lock bail diameter of 8 mm.

Mechanical OFF- and ON-Position Interlocking
Mechanical interlocking provides a physical method of retaining a switch mechanism in a defined operating state. The ABB OTZT2L is specifically configured for interlocking in both the OFF and ON positions, allowing the applicable switching assembly to be mechanically secured against unintended operation when the interlock is engaged.
The mechanism-mounted arrangement provides a compact, manufacturer-matched solution for industrial switching equipment. With provision for a lock bail diameter of up to 8 mm, the OTZT2L is suited to switchboards, machinery panels and electrical distribution systems where controlled mechanical locking of the selected operating position is required.
Typical Applications
- ABB OT/OS315–400 switching assemblies.
- Industrial switchboard isolation systems.
- Machinery power switching equipment.
- Electrical distribution panels.
- Control and automation cabinets.
- Installations requiring mechanical interlocking in both OFF and ON positions.
