1. Steffen FI adapter
With the versatile FI plug (available optionally) and the mobile FI adapter, you are safely protected. These residual current devices detect alternating and pulsating direct currents and compare the incoming and outgoing currents with each other. If there is a deviation of more than 30 mA, the supply line is disconnected from the network within milliseconds. The FI devices prevent life-threatening electric shocks that can occur due to faults in wiring and equipment. They are ideal for use with electric garden tools, Christmas lights, workshop tasks, and more. High cold tolerance down to -25 °C, with undervoltage release.
