This Siemens 3RV29211M signaling switch is an accessory for the 3RV2 series of circuit breakers. It features a design that provides separate tripped signal and short circuit alarm capabilities, with one normally open (NO) and one normally closed (NC) instantaneous contact.
The switch is designed for plug-in fixing and utilizes screw-type terminals for auxiliary and control circuit connections. It supports solid and finely stranded conductors with cross-sections ranging from 0.5 to 2.5 mm², and AWG cables from 18 to 14.
Operational current ratings include up to 10A at AC-12 across various voltages (24V, 230V, 400V, 690V) and up to 6A at AC-15 at 24V, with lower ratings at higher voltages. For DC-13 applications, it can handle up to 2A at 24V, decreasing to 0.25A at 250V.
The operating ambient temperature range is -20°C to +60°C, with storage temperatures from -50°C to +80°C. The dimensions are 18mm in width, 90mm in height, and 68mm in depth. This signaling switch carries CE, UL, CSA, and CCC certifications.
The operating ambient temperature range is -20°C to +60°C.
It has 1 NO and 1 NC instantaneous contact.
Screw-type terminals are used for the auxiliary and control circuit.
The maximum operational current at AC-12 is 10 A.
The maximum operational current at AC-15 and 24V is 6 A.
The dimensions are 18mm in width, 90mm in height, and 68mm in depth.
