Differential circuit breakers (

Differential circuit breakers (AD-12 AD-14) provide effective protection of people from electric shock if it is touching the conductive parts of electrical equipment or elements that may assert to get energized as a result of damage to isolated current-carrying time-ting. This dyfavtomat provides effective protection against electrical short-circuit and overload currents. In addition, in some performances and AD-12 AD-14 provides protection against surge currents perenap-ruhy online.

The design of the differential automaton is a connection of two functional units: Electronic module of differential protection and automatic switch. Electronic module consists of a differential-th current transformers, electronic amplifier of degree-volume devices, Executive electromagnetic discharge.
Installation performed on 35 mm mounting DIN - rail, vertical position, radically.
Switches Differential VD1-63, PRE-2001 PRE-2002 are designed to protect people from electric shock if it is touching the conductive parts of electrical equipment or elements that may become subject to tension as a result of damage to insulation. Using switch VD1-63 should be consistent with it include a circuit breaker or VA 47-29 VA 47-10.
Installation is carried out on 35 mm mounting DIN - rail in two - and four pole versions.
