The A-B 440T-MDCLJ10CDDD Trapped Key Interlock provides a robust solution for ensuring workplace safety by securing equipment in a safe state until maintenance or repairs are complete. Crafted from durable stainless steel, this interlock system is built to withstand harsh industrial conditions, including exposure to water and dust.
It operates on a principle where a specific key is trapped inside the lock mechanism, which can only be removed once the equipment is safely secured, preventing accidental activation. This process complies with international safety standards such as OSHA and ISO 14119, ensuring that all personnel involved in the maintenance process are protected from harm.
The A-B 440T-MDCLJ10CDDD includes multiple keys for different levels of access control, allowing managers to assign specific keys to authorized personnel. Its compact size of 200mm x 150mm x 50mm (LxWxH) makes it easy to install in any industrial environment, and its lightweight design at just 3kg ensures it won’t add unnecessary weight to already complex setups.
With a wide operating temperature range from -20°C to +60°C, this interlock is suitable for use in a variety of climates, making it a reliable choice for global industrial operations. Furthermore, its waterproof and dustproof design ensures long-lasting performance even in challenging environments.
