Product details

At 45 mm wide, it occupies a single modular slot in a DIN-rail panel layout, with 117 mm depth to account for wiring clearance and arc chamber volume.

Coil and switching characteristics

Maximum switching frequency varies by duty: 1,000 operations per hour at AC-1 (resistive), 750/h at AC-2 and AC-3 (motor starting and running), and 250/h at AC-4 (plugging/reversing). The AC-3e rating also caps at 750/h.

Auxiliary contact ratings and operating conditions

This variant ships without an auxiliary switch block, but the main contact ratings at various DC voltages are specified: 6 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, and 0.2 A at 440 V. These are the DC-13 (solenoid/electromagnetic load) ratings for the main contacts — useful when switching DC control loads directly.

Frequently asked questions

What is the closest functional second-source to the 3RT2016-1CM27?

The 3RT2016-1AP01-ZX95 is a peer variant in the same SIRIUS size S00 family, but it carries a different coil voltage and may include factory-mounted options. Verify coil voltage and auxiliary contact configuration before substituting — the base contactor frame and mounting footprint are identical.

What is the depth of the 3RT2016-1CM27?

The depth is 117 mm, measured from the mounting surface to the furthest projection of the arc chamber or terminals.

What conductor sizes does the 3RT2016-1CM27 accept?

Solid or stranded conductors from 0.5 to 4 mm² are accepted. For two conductors per terminal, the combinations are 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm².

Will the 3RT2016-1CM27 drop into a panel specified for the 3RT2016-1AP01-ZX95 without rewiring?

The mounting footprint and DIN-rail clip are identical — both are size S00 with 45 mm width and the same screw/snap-on rail attachment. However, if the coil voltage differs, the control wiring must be verified. The main power terminals accept the same conductor range.

What compliance documentation is available for the 3RT2016-1CM27?

Standard Siemens SIRIUS contactors carry RoHS, REACH, UL, and IEC certifications. Specific declarations can be provided with the shipment upon request.
