Protects against undervoltage For Siemens 3RV2 circuit breakers Screw terminal connections Reliable AC voltage operation Compact design

Product description

The Siemens 3RV2902-1AF0 is an undervoltage release designed for use with Siemens 3RV2 circuit breakers. It operates at 110 V AC/50 Hz or 120 V AC/60 Hz and features screw terminals for secure connection. This device provides essential protection by ensuring the circuit breaker trips when the supply voltage drops below a predetermined level.

This undervoltage release is crucial for applications where maintaining stable power is critical, such as in motor control systems, industrial machinery, and building automation. It helps prevent damage to equipment and ensures safe operation by immediately disconnecting power during voltage sags or failures.
