The contactor mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, and the mounting position allows +/-180° rotation on a vertical surface plus +/-22.5° tilt forward/backward. That means it fits a panel layout without fighting the orientation. ## Panel fit and clearances At 45 mm wide, 58 mm tall, and 73 mm deep, this contactor sits in a standard S00 footprint. That keeps the arc chamber vented and the terminals accessible for a screwdriver. Wire range accepts 0.5 to 4 mm² solid or stranded, and up to 2x 4 mm² or 2x (0.5 to 1.5 mm²) for paralleled feeds — no holes in the box for a terminal adapter. Rated switching frequency varies by duty: 1 000 operations per hour at AC-1 (resistive), 750/h at AC-2 and AC-3 (motor start/run), and 250/h at AC-4 (plugging/inching). The AC-3e rating also sits at 750/h. The auxiliary contact is rated 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. That covers most control-voltage rails in a panel.","metaTitle":"Siemens 3RT2016-1BB42-ZX95 SIRIUS Power Contactor, 24 VDC Co","metaDescription":"Siemens SIRIUS 3RT2016-1BB42-ZX95 power contactor, 24 VDC coil, Size S00, screw terminals, auxiliary switch included.

Both are Size S00 power contactors with screw terminals and an auxiliary switch, but the coil voltage differs — 24 VDC on the -1BB42 versus 24 VAC on the -1AG62. The panel footprint and wire ranges are identical, so a swap requires changing the control voltage source, not rewiring the power circuit."},{"question":"Will 3RT2016-1BB42-ZX95 drop into a panel specified around 3RT2016-1AG62 without rewiring?","answer":"Yes, the mechanical footprint is identical — same 45 mm width, 58 mm height, 73 mm depth, same DIN-rail clip, same screw-terminal layout. The only difference is the coil: 24 VDC on the -1BB42 versus 24 VAC on the -1AG62. If the panel already supplies 24 VDC, it drops in. If it supplies 24 VAC, you need a DC supply or a different coil variant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT2016-1BB42-ZX95","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/3RT2016-1BB42-ZX95 when reusing this data.
