(2) AL (Alarm switch), AX (Auxiliary switch)
● AL (Alarm switch) is for indicating trip state of the circuit breakers electrically.
● AX (Auxiliary switch) is for indicating ON/OFF state of the circuit breakers electrically.

Note 1. When used for DC circuit, pay attention to polarity.
2. The dots of terminal marking shown in above examples means
the sequence number of accessories.

Note 1. For model of breakers to be assembled each type of
micro switch, refer to the catalogue.
2. Practice insulated termination to the lead wires not
used.
3. Unusual resistance is indicated in some cases when
measured at minute current of a digital switch, for
example.
