Siemens 3VU1300-1MN00 Molded Case Circuit Breaker

Siemens 3VU1300-1MN00 is a three‑pole motor‑protective molded‑case circuit breaker (MCCB) in the SENTRON 3VU family, designed for motor control applications in industrial panels. It is rated for 14–20 A and supports a maximum voltage of up to 600 V AC, making it suitable for three‑phase motor circuits where precise overload protection is required. The device includes integrated auxiliary contacts (1 normally open and 1 normally closed) and uses screw terminals for secure wiring, enabling straightforward installation in Siemens 3VU‑series motor control assemblies. With its compact molded‑case construction and 3P arrangement, it provides both overload and short‑circuit protection for motors within the stated current range, and it is intended for use as part of motor protection schemes in Siemens SENTRON control systems. This model is commonly employed in motor starters and protection panels where reliable, plug‑and‑play compatibility with other 3VU components is desired, helping to simplify panel layouts while delivering proven protection for industrial motors.
