The Rittal SZ 2577000 is a plastic handle for latching locks, specifically designed as an alternative to the standard lock insert with integrated security cylinder insert. It is used for secure locking of enclosures and housings in industrial applications, with lock number 3524 E. Version A allows universal adaptation to various lock nose types, particularly variants AX and KX. The handle is made of glass-fibre-reinforced polyamide, ensuring high mechanical strength and resistance to mechanical stress and chemical influences. The RAL 9011 colour ensures uniform visual design in industrial environments.

Applications

The SZ 2577000 is used in industrial electrical engineering and machine building, where secure and robust locking of enclosures is required. It is particularly suitable for systems operating in environments with increased mechanical stress or in areas with special safety requirements. Use is in accordance with project-specific material release lists from the respective brand, ensuring compliance with quality and safety standards.

Functions and Equipment in Detail

The handle features an integrated security cylinder insert, enabling controlled access control. Lock number 3524 E is specifically designed for use with lock noses AX and KX, ensuring universal compatibility with various lock variants. The PU sealing provides a tight seal and protects the interior of the enclosure from dust and moisture. The clamp made of galvanised steel sheet ensures stable fixation and prevents displacement of the lock under load.

Technology Explained Simply

The housing made of glass-fibre-reinforced polyamide offers high strength with low weight. This material combination is particularly resistant to mechanical stress, such as frequent opening and closing, as well as chemical influences common in industrial environments. The plastic lock nose is designed to fit easily into the corresponding locking mechanisms and ensures secure latching. The fixing screw enables simple and secure mounting on the enclosure.

Compatibility and Accessories

The SZ 2577000 is compatible with lock noses AX and KX, commonly used in many Rittal enclosure systems. Lock number 3524 E is specifically designed for this application and ensures secure and reliable latching. Other locks can be provided upon request, increasing flexibility in selecting the appropriate lock. The delivery includes two keys, the plastic handle, the sealing, the clamp, the lock nose AX, the lock nose KX, and the fixing screw.

Installation and Mounting

Mounting is done by simply inserting the clamp into the designated holes in the enclosure and securing it with the included screw. The lock nose is inserted into the locking mechanism, where lock number 3524 E automatically engages. The plastic handle is then placed onto the lock nose and locks via the integrated lock. Installation requires no special tools and can be performed quickly and easily.

Operational Advantages

The SZ 2577000 provides reliable and secure locking that meets the requirements of industrial environments. The use of glass-fibre-reinforced polyamide ensures long service life and high resistance to wear. The integrated security cylinder lock enables controlled access control, increasing the safety of the system. Easy installation and maintenance reduce labour effort and operating costs. Delivery with all necessary components, including the two keys, ensures immediate readiness for use without additional purchases.
