3-phase distribution panel for 8 kW to 16 kW monoblock units

The distribution panel is designed for three-phase heat pumps with a capacity of 8–16 kW and provides power supply, protection, and control for all associated power and control circuits. The distribution panel is therefore designed for phase conductors L1, L2, L3, and N, along with the protective conductor PE.

The distribution panel is equipped with a NOARK Type 25/4/0.03-F Ex9L-H 4-pole residual current device (RCD) with a sensitivity of 30 mA, separate 3-pole NOARK Ex9BN 3P B16 circuit breakers for the power outputs, a 1-pole 16B circuit breaker to protect the boiler heating element, and a B2 circuit breaker for the auxiliary control circuit.

The control sections are implemented using three NOARK Ex9CH16M modular relays with a rated current of 16 A. The relays enable automatic switching of the control outputs as well as manual control as needed for maintenance or operation.
