SIEMENS 3VU1301-1MJ00 Motor Protection Circuit Breaker – SIRIUS 3VU Series
When a motor protection circuit breaker fails or goes missing on the production floor, the consequences are immediate and costly: unprotected motors become vulnerable to overload and short-circuit faults, leading to unexpected downtime, equipment damage, and potential safety hazards. In high-demand industrial environments — from conveyor systems to pump stations — every minute of unplanned stoppage translates directly into lost revenue and compromised operational integrity. The SIEMENS 3VU1301-1MJ00 is the critical safeguard that stands between your motor and catastrophic failure.
The 3VU1301-1MJ00 belongs to SIEMENS’ SIRIUS 3VU series — a globally recognized line of motor protection circuit breakers engineered for compact panel installations and reliable motor branch circuit protection. Within the 3VU family, this model is positioned as a robust, manually-operated device combining thermal-magnetic trip technology with a compact form factor, making it a preferred choice for OEMs and panel builders worldwide. The SIRIUS 3VU series is deployed across hundreds of thousands of industrial installations globally, trusted for its consistent performance in demanding environments.
