This Siemens 3RV29012E is a transverse auxiliary switch, part of the SIRIUS product line, designed for front mounting on 3RV2 series circuit breakers. It provides one normally open (NO) and one normally closed (NC) instantaneous contact.
The switch is suitable for circuit breaker sizes S00, S0, S2, and S3. It features spring-loaded terminals for electrical connections, supporting solid conductors from 0.5 to 2.5 mm² and finely stranded conductors from 0.5 to 1.5 mm². The operational current ratings include up to 2.5A at 24V and 230V for AC-12, up to 2A at 24V and 0.5A at 230V for AC-15, and various DC-13 ratings up to 1A at 24V.
With an IP20 protection class on the front, it offers finger-safe touch protection. The operating temperature range is -20°C to +60°C, with storage temperatures from -50°C to +80°C. The compact dimensions are 45mm width, 13mm height, and 17mm depth, with a plug-in fixing method for easy installation.
Certifications include CE, UL, CSA, and CCC. This auxiliary switch is an essential accessory for expanding the functionality of compatible Siemens circuit breakers.
It has 1 normally open (NO) and 1 normally closed (NC) contact.
AC-12: 2.5 A at 24 V and 230 V; AC-15: 2 A at 24 V and 0.5 A at 230 V; DC-13: 1 A at 24 V, 0.3 A at 48 V, and 0.15 A at 60 V.
The operating temperature range is -20 to +60 °C. Storage temperature range is -50 to +80 °C.
It uses plug-in fixing for mounting onto compatible circuit breakers.
The front side is rated IP20 per IEC 60529 with finger-safe touch protection from vertical contact.
It is designed for use with Siemens 3RV2 circuit breakers in sizes S00, S0, S2, and S3.
It features spring-loaded terminals.
