The control supply is AC; the magnet coil draws 0.24 W holding power at DC. Main contacts are 3 NO; no NC main contacts are fitted. Auxiliary contacts are rated for PLC-level signals (17 V, 5 mA), making them suitable for direct digital input interfaces without interposing relays. The AC-3 rating at 690 V defines the maximum operating voltage for motor switching — this contactor handles motor loads up to that line voltage in standard starting/running duty. The DC-13 rating at 220 V (0.3 A) covers inductive DC loads such as solenoid valves or DC brake coils. For AC-3 duty, the maximum operating rate is 800 operations per hour; for AC-4 (plugging/reversing), it drops to 250 operations per hour. These rates govern thermal rise in the contactor — exceeding them shortens electrical life. ## Mounting and Integration — DIN Rail, Side-by-Side, and Orientation Side-by-side mounting is permitted, so multiple contactors can pack tightly on the rail without derating. ## Fuse Coordination and Short-Circuit Protection These values assume the main circuit is protected by the listed fuse types — essential for selectivity studies in panel design.","metaTitle":"Siemens 3RT7027-1AM00 SIRIUS Contactor, 3-pole AC-3 690V, S0","metaDescription":"Siemens 3RT7027-1AM00 SIRIUS contactor, 3-pole, AC-3 rated 690V, S0 frame, IP20, screw terminals.
