SZ2418.000 Rittal SZ2418 SAFETY LOCK 24VDC 8W 24 V

Why Choose the Rittal SZ 2418.000 Safety Lock?

The Rittal SZ 2418.000 is a 24 V DC safety lock designed for enclosure doors to help protect personnel against contact with live electrical equipment while the master switch is switched on. The electrically operated interlock prevents access to energised equipment, providing an important additional safety function for industrial control cabinets and machinery.

The safety lock operates by locking the enclosure door while the master switch is ON. Mains power can only be enabled while the door is closed, and an additional closing contact monitors the locking magnet. This interlocking principle helps ensure that enclosure access and electrical power are controlled together in safety-conscious industrial installations.

Operating from a 24 V DC supply with a power consumption of 8 W, the SZ 2418.000 is suitable for Rittal VX, VX SE, TS and AX enclosure systems. The complete package includes the lock, actuator, angle bracket and assembly parts required for installation.

Key Advantages

• Helps prevent access to live electrical equipment while the master switch is on.
• Automatically locks the enclosure door when the master switch is ON.

Controlled Access to Energised Electrical Equipment

Electrical enclosure safety locks provide an important interlocking function where access to live components must be controlled. The Rittal SZ 2418.000 locks the enclosure door whenever the master switch is switched on and only permits mains voltage to be enabled while the door is closed, helping reduce the risk of accidental contact with energised equipment.

The integrated monitoring arrangement also allows the locking magnet to be supervised through an additional closing contact. For two-door enclosures, a suitable door-operated switch is required for the overlapping door to provide the corresponding enclosure-door-closed indication.

Typical Applications

• Industrial electrical control cabinets.
• Rittal VX and VX SE enclosure systems.
• Rittal TS and AX enclosure installations.
• Machine control and automation panels.
• Electrical distribution and switching equipment.
• Manufacturing and production machinery.
• Enclosures containing live electrical equipment requiring controlled access.
