DFS 4 A HT: Heat-proof residual current circuit-breaker
We have a newcomer to the Doepke product range:
The DFS 4 A HT (high temperatures) is particularly resistant to high temperatures. This makes the pulsating current and AC current-sensitive RCCB ideal for use in outdoor distribution boards that are exposed to strong solar irradiation and at other locations exposed to high temperatures.
The DFS 4 A HT functions reliably at temperatures of up to 75°C, meaning that it can carry the full rated current of 40 A. As a result, no derating is required at temperatures of up to 75°C.
The circuit-breaker is also more resistant to damaging environmental influences such as cold, dust, noxious gases and moisture.
