Product details

At 45 mm wide, 57.5 mm tall, and 72 mm deep, this S00 frame fits tight panel layouts where every millimeter of DIN rail counts. The contactor is rotatable ±180° on a vertical mounting surface and tiltable ±30° front-to-back, giving flexibility in crowded enclosures.

Ratings that matter for the panel

The 24 VDC coil draws 4.4 VA at 50 Hz and 0.27 A at 60 Hz — a modest load that a standard 24 VDC power supply handles without drama. The switching times are 4 to 30 ms for AC and 25 to 100 ms for DC, with an arcing time of 10 to 15 ms — useful data for coordinating with upstream protection. Terminal capacity accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid or stranded — covers standard control wiring. The auxiliary contacts are rated 9 A per NO and per NC contact, enough for signaling back to a PLC input card.

The S00 frame is the smallest SIRIUS contactor footprint, so it's the go-to for auxiliary contactors or small motor loads where panel real estate is tight. The screw terminals are clearly marked and accept AWG 20-14 for main contacts, with a single 12 AWG also allowed.
