The Siemens 7KT0310 is an industrial SMART 7KT Multifunction Meter engineered for comprehensive energy monitoring and power management. It provides Class 1 accuracy for measuring electrical parameters across power distribution networks, control panels, and automation systems.
Technical Overview
- Measured Metrics: Active/reactive/apparent energy, active/reactive/apparent power, line-to-line and line-to-neutral voltage, phase current, neutral current, total percentage harmonics (THD), frequency, and power factor.
- Accuracy: Class 1 for energy parameters. Voltage and current accuracy sit at ±0.5% of full scale.
- Connectivity: Built-in Modbus RTU communication interface over serial networks.
- Physical Profile: Standard 96 x 96 x 50 mm panel-flush housing featuring an integrated LCD screen and a front-facing IP65 protection rating against dust and water ingress.
- Power Supply: Wide auxiliary input range of 95–240V AC (50/60Hz).
Key Operation Guide
The device features four navigation keys (F1, F2, F3, F4) beneath its LCD screen to scroll through metrics and change setups:
- Viewing Device Serial Number: Press and hold F3 for 5 seconds to display the unique 8-digit serial number.
- Auto-Scroll vs. Manual Mode: Press and hold F4 for 3 seconds. Auto mode cycles through metrics every 5 seconds.
- Entering Configuration Setup: Press F3 + F4 simultaneously for 3 seconds.
- Password Protections: The system default configuration password is 1000. Use F1 to toggle between digits and F2/F3 to alter numerical values. Note: Resetting critical parameters demands a higher authority code equivalent to your configuration password plus one (Default: 1001).
Local Availability
In Malaysia, this component is distributed as a ready-stock part for panel builders and system integrators. It can be found via local platforms:
- Industrial Procurement: Distributed through B2B engineers such as GEASB.
For step-by-step wiring configurations, you can reference the official Siemens SMART 7KT0310 Manual (PDF).
