Product description

The Siemens 3RH1911-1FA20 is an auxiliary switch block designed for contactor relays and motor contactors. It provides two normally open contacts (2 NO) according to EN 50005 and comes with size S00 screw terminals.

This original type is no longer in production and has been succeeded by the 3RH2911-1HA20 – a good choice when you want to keep existing S00 installations exactly as built. The block was removed from a running system and is used.
