Ambient temperature*
Operating:
Single- and double-pole standard, bifurcated-contact Relays: –25°C to 55°C (with no icing)
(–25°C to 70°C if carry current is 4 A or less)
All other Relays: –25°C to 40°C (with no icing)
(–25°C to 55°C if carry current is 4 A or less)
Ambient humidity
Weight
Operating: 5% to 85%
Single- and double-pole: approx. 40 g, three-pole: approx. 50 g, four-pole: approx. 70 g
Note: 1. The values given above are initial values
2. The upper limit of 40°C for some Relays is because of the relationship between diode junction temperature and the element
used.
