Panel fit and clearances
The 3RT2026-4AG60: At 45 mm wide and 85 mm tall, the S0 frame fits standard DIN-rail spacing. Depth is 97 mm, which includes the arc chamber and auxiliary block.
Duty cycle and ratings
Maximum switching frequency depends on duty: 1,000 cycles/hour at AC-1 (resistive), 750 cycles/hour at AC-2 and AC-3 (motor starting/running), 750 cycles/hour at AC-3e, and 250 cycles/hour at AC-4 (plugging/inching). The auxiliary contact ratings span from 10 A at 24 V up to 21 A at 480 V, with a 3 hp rating at 230 V — this covers pilot duty and small motor loads through the auxiliary block. Arcing time is 4 to 16 ms at AC, with a typical value of 10 ms.
Environmental and connection details
The magnet coil connection uses a ring cable lug connection — factor that into your wiring list. The contactor is rated for 50/60 Hz operation with values of 0.25 at 50 Hz and 0.28 at 60 Hz (likely power factor or VA rating for the coil).
