Product Description

Siemens 3RH2911-1GA22 Contact Aux 2NO 2NC

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
