Automatic switches of the differential current AVDT

Automatic switches of the differential current AUDT are designed to protect people from electric shock in case of damage
electrical insulation, to prevent fires due to leakage current earth leakage and overload protection and short circuit
in the AC voltage of 400 V and frequency 50 Hz.

Automatic switches of the differential current AVDT with built-in protection against over currents responds not only to sinusoidal variables differential currents, but pulsating constant differential currents. A source of pulsating current is, for example, washing
machines with speed controllers, adjustable lights, televisions, personal computers and other

Advantages of the circuit breaker differential current AVDT


Compact design automatic switch controlled by the differential current with a built-in over-current protection
Rated conditional short-circuit current 6000 And allows you to set automatic switches of the differential current AVDT
as an introductory machine protection
The operating characteristic in the presence of a differential current - type And provides universal protection against electric shock in case of accidental
unintentionally touching a conductor, and protection against leakage currents.
High electrical resistance - not less than 6000 inclusions.
Silver soldering on the pins.
A wide range of rated currents (6A,10A,16A,25A,32A) and the rated interrupting differential current (10mA, 30mA, 100mA, 300mA)
The position indicator contacts.
Extended operating temperature range from -25 °C to +40 °C.
A notch on the contact terminals reduce heat loss and increase the mechanical strength of the connection.
Ergonomic TEST button to test the device and connection.
Main contacts 4-pole circuit breaker differential current AVDT designed so that neutral
the contact closes earlier on and off later that allows you to avoid the unbalance voltage of the load, similar to "cliff zero" in the network.
Connectivity universal contact state CDU and release independent of PH 60.
