The main contact path is rated 10 A at 24 V AC-12 (resistive), and for motor duty at 400 V it handles 4 kW in AC-2 (slip-ring motors) and 8.5 A in AC-4 (plugging/inching). Across higher voltages, the motor power ratings climb to 4.5 kW at 500 V and 5.5 kW at 690 V — so this one contactor covers 400 V through 690 V three-phase motor circuits within its thermal current envelope. The auxiliary contact block carries 2 instantaneous contacts, wired via the same spring-loaded terminal system as the main circuit. Spring-loaded terminals on the main circuit accept 2x (0.25 to 2.5 mm²) solid or stranded copper, or 2x (24 to 14 AWG). The contactor is rated for side-by-side mounting with zero gap, keeping rail space tight — the body is 45 mm wide, 60 mm tall, and 114 mm deep. ## Environmental limits and approvals Operating temperature spans -25 to +60 °C, with a maximum operating altitude of 2 000 m and pollution degree 3 (conductive pollution, typical for industrial panels). The enclosure carries IP20 on the front and at the terminals — finger-safe but not washdown-rated, so it lives inside a sealed cabinet, not on the machine frame. Coil pickup is guaranteed at 85 % of rated voltage (20.4 V DC) and dropout below the holding threshold.","metaTitle":"Siemens SIRIUS 3RT1016-2BB44 Power Contactor, 24 VDC Coil, 1","metaDescription":"Siemens SIRIUS 3RT1016-2BB44 power contactor, size S00, 24 VDC coil, 10 A rated operational current.

The difference is the coil voltage — 3RT1016-2BB44 uses a 24 V DC coil, while 3RT1016-2AP02 is an AC-coil variant. If the panel's control voltage is 24 V DC, the swap is straight; if the original was AC-powered, you will need to change the coil supply."},{"question":"What is 3RT1016-2BB44's listed depth?","answer":"The depth is 114 mm, which together with the 45 mm width and 60 mm height defines the panel space needed."},{"question":"What compliance documentation does Siemens provide for 3RT1016-2BB44?","answer":"The reference code per DIN EN 81346-2 is Q.
