DZL18-20 Leakage Breaker
Applicable in the single-phase circuits of AC 50Hz, 220V of voltage and below to 20A of rated current to protect against electric shock and also to protect the circuit and the equipments against overload and over-voltage as well as the fire disaster caused by the grounding-failed current due to the damage of the isolagion, when in series with RL1 fuse, to protect against short-circuit.
