Description

The Siemens 3RH1921-1LA11 Auxiliary Switch Block is a compact, two-pole module designed for integration with motor contactors. It features one normally open (NO) and one normally closed (NC) contact configuration in compliance with EN 50005 standards. This model facilitates reliable signal switching and electrical isolation within industrial automation systems.

 

Equipped with screw terminals for secure connections, the unit accommodates cable entry from the top to optimize wiring layouts in control panels. With a lightweight design, weighing just 0.065 kg, and dimensions of 51 mm x 45 mm x 64 mm (L x W x H), it supports space-saving installations without compromising functionality.

 

Though phased out from production lifecycle without direct reorder options, the recommended successor is the SIRIUS series model 3RH2, which offers enhanced compatibility and performance improvements for contemporary applications. Engineers should reference technical documentation to confirm exact specifications prior to replacement or integration into existing systems.
