Benefits
The lineup of slim UL489 certified items contributes to the design of more compact machinery with a 1P width dimension of 18 mm.
The simultaneous conformance to various overseas standards and simultaneous marking (JIS-cULus-CE-CCC) mean that it is possible to select models regardless of the application.
An IP20 class opening/closing type terminal cover is included as standard.
Common use for AC/DC. (1P only)
The wide lineup ranging from rated currents of 0.5 to 50 A makes flexible model selection possible.
