Auxiliary contacts are included, and the main contact rating spans 18–1 A depending on duty. ## Coil and auxiliary contact ratings The coil operates on AC or DC with a rated voltage range of 83–155 V, drawing 2 VA at 50 Hz and 2 VA at 60 Hz. The auxiliary switch is rated for 10 A at 24 V, 10 A at 230 V, 3 A at 400 V, and lower currents at other voltages (e.g., 2 A at 48 V, 6 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V). The opening time is 30–55 ms for both AC and DC, and arcing time is 10–20 ms.
