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

Operating: 5% to 85%

Weight

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.
