Mechanical interlocking for size S0-S3, with 2NC contacts

Mechanical interlocking for sizes S0-S3 is designed to prevent simultaneous activation of two contactors or starters, ensuring safety of electrical circuits. The device is equipped with two normally closed (2NC) contacts that break the circuit when the locking mechanism is activated.

Application areas:

• Reversing control schemes for electric motors
• Systems with mutual command exclusion
• Protection against short circuit in case of erroneous activation

Characteristics:

• Compatibility: sizes S0, S1, S2, S3
• Contact system: 2 normally closed contacts (2NC)
• Operating principle: mechanical action during movement of the contactor's movable part
• Packaging: 1 pc.

The interlocking is installed mechanically without additional electrical switching and requires only mechanical coupling with the contactor.
