Coil acceptance is 21 to 33 VDC; inrush peaks at 2.2 A, then holds at 10 A at 24 V rated value.
Switching duty and what the frequency ratings mean
This contactor is rated for different switching frequencies depending on the load category. At AC-1 (resistive loads) it handles up to 900 operations per hour; at AC-3 (standard squirrel-cage motors) it's good for 850 ops/h. AC-4 (plugging or inching duty) drops to 200 ops/h — that's the limit for frequent reversing or jogging, and exceeding it will cook the arc chamber. The AC-3e rating matches the AC-3 figure, so no derating for the energy-efficient motor curve. Arcing time runs 10 to 20 ms, and the mechanical life is typical at 5 million operations. That MTBF of 52 years is a statistical figure for a controlled environment — in a hot, dusty panel with frequent AC-4 cycles, plan for contact inspection well before that number suggests.
Dimensions are 70 mm wide, 140 mm tall, 152 mm deep — that's a compact footprint for a Size S3 contactor. The spring-type terminals on the coil accept 2x (0.5 to 2.5 mm²) solid or stranded; main contact terminals take 2.5 to 16 mm² solid or 6 to 70 mm² stranded.
