-
【NEW!】 An L3 type adopted the front access method. So, LED unit can be changed easily, if you need to maintain or change power supply voltage.
(Please refer to the page 8 for method of removing and mounting for L3 type.） - Round and square types of nameplates can be selected

IP40 enclosure rating is available.
Since the knob position is fastened with a screw, the BHLFX type can be prevent from getting into a foreign object from the outside, also unexpected contact with live parts. A protective ground terminal is also provided.
