Xtend Solarmi NLQ4-125/4P

Automatic transfer switch with passive 4P power contacts and control inputs for managing devices depending on mains availability.

The switch enables automatic transfer between two power sources or controlled switching of appliances based on power availability. The device includes a control input A (primary) and a support input B. When voltage is present on input A, the switch automatically switches to position I (power A). In case of a failure on input A and available voltage on input B, it switches to position II (B).

Power contacts can also be controlled manually using the slider switch in the “manual” position or when no voltage is present on control input B. The device function is independent of voltage on the power contacts, allowing isolated use, for example, for switching DC voltage 12–24 V.

  • Rated operational current 63 A at 400 V and frequency 50–60 Hz
  • Fast transfer time ≤ 30 ms for minimal power interruption
  • 4 changeover contacts (4P) with insulation voltage 690 V AC
  • Automatic and manual operation via slider switch
  • Option to use one non-isolated network for both inputs
  • Universal use for source transfer or appliance control
  • Compact dimensions 142 × 96 × 76 mm

Application as a transfer switch
Enables switching between two power sources, such as mains and photovoltaic system, UPS, or generator. The connection can also be made inversely – connect the mains to input I (A) and the backup source to input II (B).

Controlled appliance switching
Ideal for automatically switching on selected appliances when power is available at input I (A), such as storage tank heating, water heater, EV charging, or pumps. When a backup source is connected to the power contacts, the appliance can be switched to the backup supply.

Important note
When used as a transfer switch, both network voltages must match within a tolerance of ± 15%. For proper operation, control voltage must be present on both inputs A and B (AR,AN+BR,BN).
