The coil is rated 24 VDC and includes a built-in diode surge suppressor, so you don't need an external flyback diode across the coil terminals — the holding power is a steady 1.4 W, which keeps heat dissipation low in a crowded enclosure. Switching capacity covers a range of motor duties: at AC-3 (standard motor start/run) it handles 3.5 kW at 500 V and 4 kW at 690 V. For resistive loads (AC-1) the maximum operating current is 10 A at 24 V and 6 A at 230 V. The contactor is also rated for AC-4 (plugging/reversing) at 6.5 A at 400 V.
Main power terminals are screw-type, accepting 2 x (0.5 to 1.5 mm²), 2 x (0.75 to 2.5 mm²), or up to 2 x (0.75 to 4 mm²) solid or stranded conductors. AWG equivalents are 2 x (20 to 16), 2 x (18 to 14), and 1 x 12. Short-circuit protection: with Type 1 coordination, use a gL/gG fuse rated up to 35 A. This matters when you're coordinating with upstream breakers in a motor control center. No special conformal coating required for typical panel use.
The 24 VDC coil with diode suppression is a common variant, and the S00 frame is widely used in light industrial control.
