The Siemens 3RV1955-5GA0 is a set of phase barriers, 100 mm in length, designed specifically for size 3RV13 5-6 units within the SIRIUS motor starter protector family. These barriers provide the required phase-to-phase and phase-to-ground clearance inside the panel, maintaining the insulation coordination for the motor branch circuit. Per the specification, the part carries a substance prohibitance date of 08.01.2008, confirming compliance with RoHS and similar restricted-substance directives for audit purposes.
Integration and Fit
These barriers mount directly onto the 3RV13 5-6 frame, snapping into the designated slots between the main circuit terminals. The 100 mm length covers the full arc chamber depth, ensuring the creepage and clearance distances specified in IEC 60947-4-1 are maintained. No additional hardware or panel modification is required for standard DIN-rail or screw-panel mounting of the base unit.
