Residual current protection for the energy transition - Heat Pumps

The new DFS 4 HP (HP for heat pump) has been specially developed for the
protection of Heat Pumps. The protection level of the AC/DC sensitive residual
current circuit breaker meets all requirements of heat pump manufacturers. In
addition, the HP-optimised short-time delay ensures increased system availability.

• increased system availability
• meets the requirements of all heat pump manufacturers
• also available as FI / LS-combination
• energy-efficient due to low power loss
