Product description

Residual current circuit breakers EFI B and B+ type
Residual current sensitivity - UNIVERSAL
B type
AC + A + smooth direct current + high frequency (1kHz)
B+ type
AC + A + smooth direct current + high frequency (20kHz)

Residual current circuit breakers EFI are used for protection against indirect touching of parts under voltage, for
prevention of lasting voltage on earthed parts which should appear because of a defect in the electrical installation
and for protection against direct contacts of parts under voltage. Residual current circuit breakers can be used in TN-S, TN-C, TT and IT network systems or with other words in all systems where neutral and protective
conductor are separated (VDE 0100 Part 410).
Types - Our programme comprises residual current circuit breakers which are sensitive to alternating residual current
(AC-type) and residual current circuit breakers which are sensitive to alternating and pulsating direct current (A-type).
Residual current circuit breaker with integral overcurrent protection KZS -1M
Residual current circuit breaker with integral overcurrent protection KZS-2M
KZS (KZS-2M,KZS-3M,KZS-4M) is a residual current circuit breaker combining the
features of a miniature circuit breaker and a residual current circuit breaker and is functionally
independent on line voltage. Used primarily in circuits with an increased requirements regarding
touch voltage such as circuits of portable appliances, in kindergartens, schools, hospitals etc.
