3WL10

The air circuit breaker is an integral part of an economically efficient power distribution system that is designed to protect personnel and material assets. The 3WL10 air circuit breaker is an IEC circuit breaker (3WL1) with frame size 0 (3WL10) and is an addition to the existing 3WL1 IEC portfolio.

The 3WL10 air circuit breaker meets the following requirements:

High breaking capacity
Selective protective response, integrated metering function with internal voltage tap and expansion module MF Basic/MF Advanced (with electronic trip units of the 6-series)
Connection to a fieldbus communication system or Ethernet-based IP communication (with electronic trip units of the 6-series)

State symbols of the air circuit breaker

Different states of the air circuit breaker are represented as a circuit breaker symbol. The state symbol of the air circuit breaker indicates the position of the air circuit breaker in the frame. You can see whether the air circuit breaker is open or closed. The background color designates the status of the relevant message.

Colored Background of the Molded-Case Circuit Breaker Symbol for Designating the Status
Color	Message status	Meaning
Green	Green	No messages pending
Yellow	Yellow	At least one warning message or one threshold warning is pending
Red	Red	At least one trip message is currently pending
White	White	No information available about the existence of messages
