Circuit breaker VA88 MASTER of KARAT series with electronic
The circuit breaker complies with the requirements of Directive
LVD 2014/35/EU, EMC 2014/30/EU, RoHS 2011/65/EU, IEC 60947-2 .
release of IEK trademark (hereinafter referred to as circuit breaker)
is designed to conduct current in normal mode and turn off overcurrents in case
of short circuits and overloads, as well as for infrequent (up to 30 times a day)
operational switching on and off of electrical circuits in three-phase alternating
current electrical networks with voltage up to 690 V and 50 Hz.
The circuit breaker can be operated under the following conditions:
– operating temperature range from minus 25
°
Ñ to plus 60
°
Ñ ;
– utilization category according to IEC 60947-2 – Â (intended to provide
selectivity);
– non-explosive environment, not containing aggressive gases and vapors in
concentrations that destroy metals and insulation, not saturated with conductive
dust and water vapor;
– environment condition group according to IEC 60947-1 – À , Â *;
Base product data
– base altitude – no more than 2000 m, operation at the altitude of up to
5000 m is allowed with a decrease in the operating current, taking into account
the correction factor (table 1);
The electronic microprocessor-based release of the circuit breaker provides
overload protection with an inverse long tripping delay and an inverse time-
current characteristic. Short-circuit protection with adjustable instantaneous
release.
Technical parameters of the circuit breaker, depending on the standard
version, are given in table 2.
The circuit breaker is intended for use in an environment with pollution
degree 3 according to IEC 60947-1 (conductive pollution is possible or dry, non-
conductive pollution that becomes conductive due to expected condensation).
When using the circuit breaker in a group B environment, special devices
should be used to protect against unwanted electromagnetic interference .
Degree of protection of the circuit breaker case is IP30 in accordance with
IEC 60529, of terminals for connecting external conductors – IP00.
Specifications
– relative humidity – 50 % at a temperature of plus 40
°
Ñ , it is allowed to use
circuit breakers at a relative humidity of 90 % and a temperature of plus 20
