The Gewiss AC 4P 20A 30mA magnetothermal differential switch is a device that ensures high protection against overvoltages and overcurrents. It combines the functions of a circuit breaker with those of a magnetic and thermal device to precisely interrupt the electric current in case of need. This Gewiss AC 4P 20A 30mA differential magnetothermic switch offers effective protection thanks to its differential sensitivity of 30mA.
The 4-pole and 4-module Gewiss differential magnetothermal switch with 20A rated current, 30 mA rated differential current and rated voltage of 400-415V is a safety equipment widely used in domestic installations. This differential magnetothermal switch is characterized by a curve C, tripping threshold from 5 to 10 times In, for the application of ohmic-inductive circuits with medium starting currents. Furthermore, it has a breaking capacity of 6000A at 400V and ensures its tripping for differential sinusoidal alternating currents applied both suddenly and slowly increasing, in compliance with the CEI EN 61008-1 standard. Choosing a 4-pole, 4-module Gewiss magneto-thermal differential switch with technical characteristics such as those shown is a guarantee of safety and reliability.
