PRODUCT DESCRIPTION
SIEMENS 3RA1952-2F - Auxiliary Contact Block
The SIEMENS 3RA1952-2F is an auxiliary contact block designed for front-mounting on SIRIUS 3RT1 power contactors, specifically sizes S6 through S12. It expands the control circuit capabilities by providing two normally open and two normally closed potential-free contacts. This component is critical for implementing complex interlocking, status signaling, and control logic within industrial motor control applications and general automation systems.
