Note:
①
In the release mode and internal accessory code: The first digit 2 indicates electromagnetic
(instantaneous) release, and 3 indicates thermal-electromagnetic (complex) release. The last
two digits indicate the internal accessory code, or 00 if there is no accessory.
②
In HYM1L-400 and 630, the auxiliary contacts of sizes 228, 328, 248 and 348 are a pair of
contacts (i.e. one normally-open contact and one normally-closed contact), and the auxiliary
contacts of sizes 268 and 368 are three pairs of contacts (i.e. three normally-open contacts
and three normally-closed contacts). The configuration of other auxiliary contacts is shown in
Table 2.
③
The auxiliary contacts of sizes 220, 320, 240 and 340 in HYM1L-125 and 250 can be provided
with two pairs of contacts (i.e. two normally-open contacts and two normally-closed contacts),
which however, must be noted when ordering.
④
If the HYM1L series is equipped with earth leakage alarm unit module (that is, earth leakage
alarm without tripping), only the accessories of the specification with ▲ are provided.
