Spring-terminal connection
Bare and prepared flexible conductors have different permitted cross-section limits.
Product Overview
3SU1401-1BB20-3AA0 adds integrated red LED illumination to a SIRIUS ACT front-panel signaling assembly.
The spring-terminal module mounts at the rear of the holder in its center position and operates from the selected 24 V AC/DC control supply.
Key Functions
Illuminate the selected red signal point
The integrated light source supplies red illumination without a separate replaceable lamp transformer.
Accept the available control voltage
Operation at 24 V AC or DC supports common panel control supplies within the specified voltage tolerance.
Fit behind the panel holder
The narrow module attaches in the center mounting position on the rear of the SIRIUS ACT holder.
