Mechanical interlock for contactors MC-9b-150a / MC-9a/4-18a/4 UR-02

Mechanical interlocks for contactors – safety and control

The UR-02 mechanical interlock is a reliable solution providing physical protection against unintentional circuit closure during maintenance or service work. Designed for use with MC-9b-150a and MC-9a/4-18a/4 contactors, this interlock minimizes the risk of accidental device activation, protecting personnel and the installation. This is particularly important in applications requiring adherence to strict safety standards.

Application and compatibility

The UR-02 interlock is dedicated for use with the aforementioned contactor models, guaranteeing its proper operation and full effectiveness. Installing the interlock prevents the contactor from being switched on, even if a remote control attempt is made. This is a simple yet effective solution that increases safety in industrial environments and electrical installations.

Advantages and benefits

• Increased safety: The interlock physically prevents the contactor from being switched on during service work, eliminating the risk of electric shock or equipment damage.
• Simple installation: Installing the interlock is intuitive and does not require specialized tools or knowledge.
• Durable construction: Made of robust materials, the interlock ensures long-lasting and reliable operation in various environmental conditions.
• Compatibility: Specifically designed for MC-9b-150a and MC-9a/4-18a/4 contactors, guaranteeing a perfect fit and effective operation.
• Compliance with LOTO (Lockout/Tagout) procedures: The UR-02 interlock perfectly fits into LOTO procedures, enabling safe electrical energy isolation during maintenance work.
• Protection against accidental start-up: Protects against unauthorized or accidental device start-up during repairs or maintenance.

It is worth remembering that mechanical interlocks are a key element of the safety system in electrical installations. Their use helps to minimize the risk of accidents and provides protection for both personnel working on the installation and the equipment itself.
