0912020屬于電路保護的斷路器。由德國菲尼克斯電氣集團制造生產(chǎn)的0912020斷路器斷路器是一種自動操作的電氣開關，可用于保護電路免于因過載或短路引起的過流而受損?；竟δ苁窃跈z測到故障后中斷電流。與只能操作一次然后必須更換的保險絲不同，斷路器可以復位（手動或自動）以恢復正常操作。

描述 Description

The ECP… electronic circuit breaker, which has a design

width of just 12.5 mm, selectively protects all 24 V DC load

circuits. This is achieved using a combination of active

electronic current limitation and proven circuit breaker

technology including electrical isolation. The ECP… can be

plugged onto the proven TMCP SOCKET M base, which

ensures quick and easy mounting.

The ECP… can be used in applications that cover all

aspects of the switched-mode power supply unit. In the

event of an overload, switched-mode power supply units

reduce the output voltage, which means that all the

connected loads are no longer sufficiently supplied. This

means that if an error occurs in one load of a system, the

voltage will be affected in all load circuits.

The ECP… solves this problem by always limiting the

maximum possible current to 1.8 times (or 1.5 times) the

value of the set nominal current. Capacitive loads can thus

be switched on and loads are only switched off in the event

of an overload or short circuit.

An LED and integrated signal contacts indicate the

operating and error states.
