The Siemens 3RV29212M is a signaling switch from the SIRIUS product line, specifically designed for use with circuit breakers of sizes S00, S0, S2, and S3. This accessory provides a separate tripped signal and short circuit alarm, featuring one normally open (NO) and one normally closed (NC) instantaneous contact.
With a robust design, the signaling switch operates within an ambient temperature range of -20°C to +60°C during operation and -50°C to +80°C during storage. It utilizes spring-loaded terminals for reliable connections in the auxiliary and control circuits. The operational current ratings vary depending on the application, with AC-12 at 24V, 230V, 400V, and 690V all rated at 10A maximum, and AC-15 at 24V rated at 6A.
Installation is facilitated by a plug-in fixing method, and the unit has dimensions of 18mm width, 90mm height, and 68mm depth. The switch is suitable for various conductor cross-sections, including solid and finely stranded wires from 0.5 to 1.5 mm², and AWG cables from 24 to 14.
This signaling switch carries certifications including CE, UL, CSA, and CCC, indicating its compliance with international standards. It is an essential component for monitoring and signaling the status of circuit breakers in industrial and commercial applications.
The operating temperature range is -20°C to +60°C.
It has 1 normally open (NO) and 1 normally closed (NC) instantaneous contact.
It is compatible with circuit breaker sizes S00, S0, S2, and S3.
Spring-loaded terminals are used for the auxiliary and control circuit.
The maximum operational current at AC-12 for 230V is 10A.
