- Protection: Built-in disconnect function, temperature compensation, and trip-free mechanism.
- Fault Indication: Separate window for short-circuit tripping indication.
- Security: Handle is lockable to prevent unauthorized changes.
Technical Specifications
- Rated Operational Current: 80 A.
- Rated Operational Voltage: 690 V AC / 250 V DC.
- Rated Operational Power (400 V): 45 kW.
- Trip Class: 10.
- Degree of Protection: IP20 (Housing), IP10 (Main Circuit Terminals).
- Rated Frequency: 50/60 Hz.
Mounting and Installation
The device is designed for mounting on DIN rails (TH35-15 or TH35-7.5). Ensure proper clearance distances based on the voltage and mounting surface. For example, when mounting on an electrical conductive board, a distance of 1.5 mm is required for voltages up to 1000 V.
Environmental Conditions
The device operates within an ambient air temperature range of -25 to +60 °C. Storage temperature is -50 to +80 °C. The maximum operating altitude is 2000 m.
Accessories
The MS165-80 is compatible with a wide range of accessories, including auxiliary contacts (HKF1, HK1), signaling contacts (SK1, CK1), shunt trips (AA1), undervoltage releases (UA1), power in-feed blocks (S2-M3-50), and various busbars.
Practical help
Common problems
Short-circuit breaking capacity limitations
Ensure the circuit requirements do not exceed the rated breaking capacity (e.g., 30 kA at 400 V AC, 6 kA at 690 V AC).
Mounting clearance
Maintain required distances from electrical conductive boards (1.5 mm for up to 1000 V) and other devices (0 mm horizontal, 150 mm vertical).
Before use
- Verify the motor's operational power and current match the device ratings (70-80 A).
- Ensure the mounting surface is suitable for DIN rail installation (TH35-15 or TH35-7.5).
- Check that the ambient temperature is within the -25 to +60 °C range.
- Confirm the required accessories (auxiliary contacts, etc.) are available if needed.
Specs in practice
- Trip Class 10
- Standard trip class for motor protection, indicating the time-current characteristic.
- Rated Operational Power
- The maximum power the device can handle at 400 V (45 kW).
Model compatibility
- Compatible with MS116/MS132/MS165 range accessories.
- Suitable for three- and single-phase applications.
