Note: Use a 10 A fuse type gI or gG that conforms to IEC60269 as a
short-circuit protection device. This fuse is not built into the
Switch.

Characteristics
Note: 1. The above values are initial values.
2. Once the contacts have been used to switch a load, however, they cannot be used to switch smaller loads. The contact surfaces will
become rough once they have been used and contact reliability for smaller loads may be reduced.
*1. The degree of protection is tested using the method specified by the standard (EN60947-5-1). Confirm that sealing properties are sufficient for
the operating conditions and environment beforehand. Although the switch box is protected from dust or water penetration, do not use the
D4NH in places where foreign material such as dust, dirt, oil, water, or chemicals may enter through the head. Otherwise, accelerated wear,
Switch damage, or malfunctioning may occur.
*2. The durability is for an ambient temperature of 5 to 35°C and an ambient humidity of 40% to 70%. For more details, consult your
OMRON representative.
*3. Do not pass the 3 A, 250 VAC load through more than 2 circuits.
*4. This value will vary with the switching frequency, environment, and reliability level. Confirm that correct operation is possible with the actual
load beforehand.
