Product details

It carries two instantaneous normally-open contacts rated 10 A at both 24 V and 230 V, with a typical mechanical life of 30,000,000 operations.

Contact ratings and switching performance

At DC, the maximum switching frequency is 10,000 operations per hour. Voltage tolerance spans 0.8 to 1.1 times rated value at 50 Hz and 0.85 to 1.1 at 60 Hz. Rated operational currents vary by voltage: 10 A at 24 V and 230 V, 4.7 A at 60 V, 3 A at 110 V and 400 V, 1.2 A at 220 V, 0.5 A at 440 V, 2 A at 500 V, 0.26 A at 600 V, and 1 A at 690 V.

Terminals accept solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm².

Frequently asked questions

Where can I buy 3RH2122-1AP00-ZW96 and get a price?
