Omron, D4B-[]N Series

Direct opening mechanism (NC contacts only) added to enable opening contacts when faults occur, such as fused contacts.
Safety of lever settings ensured using a mechanism that engages a gear between the operating position indicator plate and the lever.
Equipped with a mechanism that indicates the applicable operating zone, as well as push-button switching to control left and right motion.
Head seal structure strengthened to improve seal properties (TÜV: IEC IP67, UL: NEMA 3, 4, 4X, 6P, and 13).
Wide standard operating temperature range:
–40 to 80°C (standard type).
Certified standards: UL, CSA, EN (TÜV), and CCC.
