Overview
The Siemens 3VU1300-1TK00 is a three-pole motor starter protector circuit breaker engineered for industrial motor protection. It combines adjustable bimetallic thermal elements with fixed magnetic trip devices to provide dual-level protection against both overload and short-circuit faults. The manual rotary switch (ON/OFF/Trip) allows direct-on-line motor starting with immediate visual fault indication, making it a cost-effective solution for motor branch circuits in manufacturing, HVAC, pump stations, and other industrial environments.
Key Features
- Adjustable thermal overload and fixed magnetic short-circuit trip elements
- 3-pole design for three-phase motor protection
- Manual rotary switch operation with integral ON/OFF/Trip control
- Auxiliary contacts: 1 NO + 1 NC for remote indication and monitoring
- Class 10 trip classification (standard motor protection per IEC 947-4-1)
- Operating frequency: 50/60 Hz for global deployment
Technical Specifications
The motor starter protector series 3VU1300 is designed to meet IEC 947-2 (now IEC 60947-2) and VDE 0660 standards. Thermal protection adjustability and magnetic trip instantaneous response combine to protect motors over a range of operating conditions. The device is rated for high interrupting capacity and is suitable for both panel mounting and DIN rail installation with screw clamp terminals.
Typical Applications
- Direct-on-line (DOL) motor starting circuits
- Motor branch circuit protection in control cabinets
- Pump and fan motor control
- Compressor motor protection
- Industrial machine tool motor control
