[ Low limit relay ]
Rating is 250V AC and 0.5A.
Rating is 30V DC and 0.5A.
CAUTION
Overvoltage and overcurrent may cause breakdown of the relay as well
as shortening its life.
It is recommended to connect a spark killer etc. to the connected load
according to AC/DC (refer to the connection examples). With a noise
killer, you can make the life of the relay longer as well as making it
resistible against noise.
Never short-circuit the load.
Should you do it, the equipment will break down.
