D4NH-8FBC Prefered types Note: 1. It is recommended that M20 be used for Switches to be exported to Europe and 1/2-14NPT be used for Switches to be exported to North American countries. 2. All models have slow-action contacts with approved direct opening mechanisms on NC contacts only. -
Page 3: Specifications
Note: 1. The values in the table on the previous page are initial values. 2. Once a contact has been used to switch a standard load, it cannot be used for a load of a smaller capacity. Doing so may result in rough- ening of the contact surface and contact reliability may be lost. - Page 4 33-34 can be used as unlike poles. Note: 1. Terminals are numbered according to EN50013. Contact forms are according to EN60947-5-1. 2. MBB (Make Before Break) contacts have an overlapping structure, so that before the normally closed contact (NC) opens, the normally open contact (NO) closes.
- Page 5 Movable contact Fixed contact (NO) Plunger Return spring Only the NC contact side has a direct opening mechanism. When metal deposition occurs, the contacts are separated from each other by the plunger being pushed in. (Conforms to EN60947-5-1 Direct Opening Operation.)
- Page 6 2. Variation occurs in the simultaneity of contact opening/closing operations of 2NC, 2NC/1NO, and 3NC contacts. Check contact operation. 3. There are a minimum of five turns of the screw thread for a Pg13.5 conduit opening and four turns minimum for a G 1/2 conduit opening.
