That 42 A figure governs the motor it can switch — sized for a 15–20 kW induction motor at 400 V, depending on duty cycle. The 120 V AC coil pulls in reliably at nominal line voltage; dropout voltage sits around 85 V, so a saggy control circuit won't hold it closed. Three power poles handle the motor feed; the built-in 1 N.O. auxiliary contact block gives you one spare signal for a PLC input or run-status lamp without adding a side-mount stack. The 120 V AC coil draws roughly 7–8 VA sealed, so a 50 VA control transformer can drive several of these plus a few pilot lights. Spring-cage power terminals accept up to 16 mm² stranded — common for the motor circuit at this current level. The auxiliary contact is wired separately from the coil terminals; no shared suppression diode to worry about on AC coils.","metaTitle":"A40-30-10-84 Contactor, 42A, 3-Pole, 120V AC Coil, EOL","metaDescription":"A40-30-10-84 IEC contactor, 42A motor current, 3-pole, 120V AC coil.
