Product Overview

The Siemens 3RH2911-1HA11 is a SIRIUS front-mounted auxiliary contact block manufactured by Siemens AG for use with selected Siemens 3RT2 contactors and 3RH2 contactor relays. This accessory provides one normally open (1 NO) and one normally closed (1 NC) auxiliary contact, offering two contact paths for industrial control circuit signaling, status indication and interlocking functions. The contacts operate instantaneously with the host switching device and use screw terminal connections. The block is designed for front snap-on mounting on compatible SIRIUS switching devices. Its rated insulation voltage is 690V AC, and the specified rated operational current under AC-15 at 230V is 6A. The 3RH2911-1HA11 is an auxiliary switching accessory rather than a standalone power contactor. The supplied actual photographs show both the physical Siemens accessory and its matching packaging, with identical catalog numbers and the 1 NO + 1 NC contact configuration. The packaging label specifies Qty: 1 and identifies the Czech Republic as the country of manufacture. Please verify your host contactor model, mounting requirements and auxiliary contact arrangement before ordering.
