Safety interlock Rittal SZ 2416.000, grey, single-piece electrical cabinet interlock

Rittal SZ 2416.000 is a grey safety interlock designed for electrical cabinets and enclosures. Supplied as a single-piece unit, this mechanical interlock prevents unintended access to cabinet interiors during operation and maintenance. It is intended for use on industrial control cabinets and switchgear where a reliable door locking mechanism is required to improve workplace safety and ensure compliance with basic access-control needs.

Advantages

The single-piece construction provides straightforward installation and minimal adjustment. Its neutral grey finish integrates with common cabinet colors and reduces visual contrast. The device offers a simple mechanical interlocking function to help prevent simultaneous access to hazardous compartments, contributing to safer service and inspection procedures.

Suitable for

• Industrial control cabinets and automation enclosures
• Low- and medium-voltage switchgear doors
• Enclosures requiring basic mechanical door interlocking
• Applications where a compact, single-piece lock is preferred

When it may not be suitable

The SZ 2416.000 provides a mechanical interlock suitable for preventing unauthorized or inadvertent opening but does not include electronic monitoring or electrical release features. It may not meet application requirements that demand integrated sensing, electrical actuation, or compliance with specific machine safety standards that require coded or monitored interlocks.

Key specifications

• Type: Mechanical safety interlock for cabinet doors
• Delivery form: Single-piece unit
• Color/finish: Grey
• Intended mounting: Door/frame installation on electrical enclosures

How to use

Install the interlock at the cabinet door and frame location specified by the enclosure manufacturer or the cabinet layout. Tighten mounting fasteners to the recommended torque and verify alignment so that the interlock engages reliably when the door is closed. Use the device to mechanically prevent door opening while internal components are live or the system is under maintenance. Periodically inspect the interlock for wear, correct engagement, and secure fastening.

What to consider before purchase

• Verify physical compatibility with the cabinet door and frame mounting details.
• Confirm that a mechanical interlock without electrical monitoring meets your safety requirements.
• Ensure the colour and form factor suit the intended enclosure and installation environment.

Usage recommendations

Use the Rittal SZ 2416.000 as part of a documented safety procedure: combine it with lock-out/tag-out practices and regular inspection schedules. If electronic monitoring or release is required, select a suitably specified interlock with those features.
