Main circuit terminals are screw-type, accepting 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid or stranded conductors. AWG equivalents are 2x (20 to 16), 2x (18 to 14), and 1x 12. That covers most panel wiring up to 4 mm² without needing bootlace ferrules, though ferruled stranded is fine within the same cross-section range. The contactor is rated for AC-2 duty at 400 V at 4 kW, and AC-4 at 400 V at 8.5 A. AC-2 covers slip-ring motor starting and reversing; AC-4 covers plugging and inching of squirrel-cage motors. For resistive loads (AC-12), the maximum operating current is 10 A. Motor power ratings at higher line voltages: 4.5 kW at 500 V and 5.5 kW at 690 V. That makes it suitable for 400 V class motors up to about 4 kW, and for 690 V delta-connected motors up to 5.5 kW, common in mining or heavy industrial installations. Short-circuit protection coordination: with type 2 coordination (no welding of contacts on fault), use a gL/gG fuse rated 20 A. With type 1 coordination (contacts may weld but no fire or shock hazard), use a 35 A gL/gG fuse. The 20 A recommendation is the one most panel designers spec for selectivity downstream of a motor circuit breaker. Degree of protection is IP20 on the front and at the terminals, which is standard for enclosed panel mounting — no finger-safe shrouding needed inside a locked cabinet. That is useful for panel documentation and for matching the part to a pre-labeled schematic.","metaTitle":"Siemens 3RT1016-1BB42-ZW98 SIRIUS Power Contactor, 24 VDC Co","metaDescription":"Siemens SIRIUS 3RT1016-1BB42-ZW98 power contactor, size S00, 24 VDC coil, 3.3 W hold, screw terminals, IP20, active production.

The S00 frame is physically smaller (45 mm wide vs. 45 mm wide for S0, but S0 is taller and deeper), and the 3RT1016 has a 24 VDC coil versus the 3RT1015's 24 VDC coil. The main difference is the current rating: the 3RT1016 is rated for higher motor currents (4 kW at 400 V AC-2 vs. lower for the 3RT1015). They are not drop-in replacements without checking the load current and physical space."},{"question":"What is the depth of this contactor?","answer":"The depth is 72 mm, which is the dimension from the DIN-rail mounting surface to the front of the device."},{"question":"What wire sizes does the screw terminal accept?","answer":"The main circuit screw terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid or stranded conductors.

However, the S00 frame is shorter (57.5 mm vs. S0's taller height) and shallower (72 mm vs. S0's deeper dimension), so there may be a gap in the panel cutout. The terminal layout and wiring are similar, but the different frame size means the mounting hole pattern on the rail is the same, but the overall envelope is smaller. It will physically mount, but the panel layout may look sparse if the cutout was sized for the larger S0 frame."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1016-1BB42-ZW98","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RT1016-1BB42-ZW98 when reusing this data.
