D4N-8C72R D4N-8D72R 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. The 1/2-14NPT 2-conduit models include an M20-to-1/2-14NPT changing adaptor. - Page 4 Note: 1. The above values 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.
