It is rated for AC-1 utilisation category at 32 A up to 415 V, meaning it is designed for resistive loads — heaters, lighting banks, or other non-inductive circuits — not motor starting.
Operating altitude is 3000 m without derating, and the permissible ambient range is -5 to 55 °C for operation, with storage from -60 to 80 °C.
Mechanical and switching characteristics
Mechanical robustness is specified for vibrations (1.5 Gn open, 3 Gn closed) and shocks (7 Gn open, 10 Gn closed), which is adequate for most fixed industrial installations but not for mobile or high-vibration environments like engine-driven equipment.
