It's sized for control circuits that need to switch DC loads up to 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. The S0 frame keeps the footprint tight at 45 mm wide, 102 mm tall, and 107 mm deep — a standard slot on a 35 mm DIN rail per DIN EN 60715.
Solid conductors from 1 to 10 mm², stranded from 1 to 10 mm², and 2x (0.5 to 2.5 mm²) for solid or stranded.
Switching frequency by duty class
Maximum switching frequency varies by duty: 1,000 1/h for AC-1, AC-2, AC-3, and AC-3e; drops to 300 1/h for AC-4. The AC-4 limit is the one that bites on reversing or inching applications — if your cycle rate pushes past 300 per hour, this contactor will overheat. Mechanical life is typical 10,000,000 operations.
Environmental limits
The storage limit is for handling and shelf life, not running — don't let a panel sit in a freezing warehouse and expect the contactor to pull in at -30 °C without pre-heating the coil.
