That 750 ops/h ceiling on AC-3 means it handles frequent starts on a conveyor or pump without overheating the contacts — it's not a continuous-duty relay, it's built for cyclic loads. Inrush current peaks at 3 A, which matters when you're sizing the control transformer or the DC supply for the coil — that's the momentary draw when the magnet pulls in. The S0 frame is 45 mm wide, 102 mm tall, and 107 mm deep. That depth is the dimension from the DIN rail mounting surface to the front of the terminals — important when you're calculating door clearance or gland-plate depth. Side clearance is 6 mm, and vertical spacing (up/down/forward) is 10 mm. Solid or stranded wire from 1 to 10 mm² fits the spring terminals; for finer control wiring, 2x 0.5–2.5 mm² is allowed.","metaTitle":"Siemens 3RT2027-2NB30-ZX95 SIRIUS S0 Power Contactor, Spring","metaDescription":"Siemens 3RT2027-2NB30-ZX95 SIRIUS S0 power contactor.
