With a 65A / 9600W rating, it’s ideal for residential, commercial, or light industrial use. It also features automated load protection, instantly shutting off power during overcurrent or over/under voltage events (up to 450V spikes). The dual connectivity - Wi-Fi and Bluetooth - ensures continuous operation and control even during network dropouts.
The built-in logger stores up to 2 months of energy data, exportable in Excel format for reporting. Designed for fast install with 35mm DIN rail compatibility, the MTS21 helps optimise energy use and safeguard connected loads.
