## Summary description

Mechanical interlock for contactors by Etipo, compatible with BLIME 112-300E series (MPN 004643602). Designed to provide mechanical prevention of simultaneous closing of multiple contactors, it ensures safer electrical switching and coordination in motor control and power distribution panels. Suitable for industrial and commercial electrical installations requiring reliable mechanical interlocking.

## Long description

The Etipo mechanical interlock for contactors BLIME 112-300E is a purpose-built mechanical device designed to prevent simultaneous closing of multiple contactors in motor control and power distribution panels. Manufactured by Etipo for the BLIME 112-300E contactor series, the interlock provides a mechanical barrier that enforces sequential operation and reduces the risk of electrical conflicts during switching operations. It is intended for use in industrial and commercial electrical installations where reliable interlocking is required to maintain safe and coordinated switching.
Advantages
The mechanical interlock offers direct, fail-safe prevention of concurrent contactor engagement without relying on auxiliary electrical circuits or software logic. Its robust construction is suited to repeated mechanical operation and minimizes the need for electronic diagnostics in straightforward interlock applications. The device integrates with existing contactor assemblies designed for the BLIME 112-300E form factor, allowing straightforward retrofit or initial installation. By providing a physical interlock, it reduces dependency on control wiring and simplifies safety verification during maintenance.
Suitable for
Preventing simultaneous operation of two or more contactors in motor starter arrangements
Interlocking contactors in changeover or transfer switch configurations
Use in distribution panels for industrial machinery and commercial electrical systems
Retrofit applications where mechanical interlocking is preferred over electrical interlocks
Key specifications
Designed compatibility: BLIME 112-300E series contactors
Function: mechanical prevention of simultaneous contactor closing
Material: steel and engineered polymer components for wear resistance (manufacturer grade)
Mounting: fits the contactor housing and fastening points intended for the specified series
Operation: positive mechanical engagement with defined travel to prevent contactor movement
How to use
Install the interlock according to the contactor manufacturer’s mechanical mounting instructions, ensuring alignment with the contactor actuator shafts or levers. Secure the device to the contactor housing using the provided attachment points and check that the mechanical linkages move freely without binding. After installation, cycle each contactor manually to verify that the interlock prevents simultaneous closing and that each contactor can operate independently when the other is in the intended locked position. Perform electrical testing of the overall control circuit only after confirming correct mechanical operation.
Usage recommendations
Use the interlock as part of a comprehensive safety and control scheme: combine mechanical interlocking with appropriate electrical protection, control logic, and lockout/tagout procedures. Periodically inspect the interlock for wear, secure mounting, and free movement, and replace worn components to maintain reliable operation.
