Schneider Electric MN21130 Auxiliary Contact Block

Schneider Electric MN21130 Auxiliary Contact Block is an auxiliary contact accessory rated for 690 V that complements Schneider Electric contactors by adding extra control contacts. This block provides additional normally open and/or normally closed contacts used to signal states, interlock circuits, or feed control logic without altering the main switching path of the primary device.

Designed as part of Schneider Electric’s control ensemble, the MN21130 expands the capabilities of a contactor in industrial electrical installations, enabling enhanced signaling, monitoring, and sequencing within automation and machine control systems. The 690 V rating indicates suitability for standard control-circuit environments found in many industrial applications.

• Voltage rating: 690 V
