Siemens Snap-On Auxiliary Contact Block, 10A, 2NO/2NC - SIRIUS Innovation Series - 3RH2911-1GA22


Closely monitor a contactor with this auxiliary contact block from Siemens. For ease of monitoring, it sends a signal to a PLC (programmable logic controller) if it detects any status changes. Installation is simple thanks to the snap-on design, which lets you clip it on the front of the main contactor with a secure hold. For long-lasting performance, it has a mechanical service life of 10 million cycles. Install this auxiliary contact block on a control panel to regulate alarm and indication systems.

• Surge voltage resistance of 6kV to withstand current overloads

• Wide operating temperature range of -25°C to +60°C for use in demanding environments

• Compact dimensions of 37.5 (height) x 36 (width) x 43.7mm (depth) for installation in tight spaces

• Contact reliability of one possible incorrect switching operation in 100 million indicates efficiency

Can I use this auxiliary contact block in high-voltage applications?


This unit has a high voltage rating of 600V DC (direct current) and 690V AC (alternating current), making it a good choice for use in high-power applications.
