Compact grey IEC contactor, DIN-rail mount, screw terminals, four poles, 110-120 V AC coil

SIEMENS

SIEMENS 3RT25171AK60 IEC Magnetic Contactor 110-120V AC 12A 4-Pole

SKU CH-7BND-T3NVS

IEC magnetic contactor with 110-120V AC coil, 12A inductive rating, four poles and DIN-rail mounting

  • Coil voltage 110-120 V AC suits standard control circuits
  • Four-pole design switches three-phase loads with neutral
  • 12 A inductive rating handles motor-starting currents
  • DIN-rail and surface mounting fits panel layouts
  • Screw terminals provide secure field wiring

SIRIUS 3RT25 4-Pole Magnetic Contactor

The SIEMENS SIRIUS 3RT25 contactor provides non-reversing motor control with four main poles rated at 12 amps inductive and 22 amps resistive load. It operates on a 110 to 120 volt AC coil and includes no auxiliary contacts as standard equipment.

Screw Terminals and DIN Rail Mounting

Connections are made via screw terminals for secure wire termination in industrial environments. The unit mounts on standard DIN rail or directly on a surface panel, measuring 3.08 inches high by 1.97 inches wide with an open-frame design that carries no NEMA enclosure rating.

Verify Coil Voltage and Pole Requirements

Confirm your control circuit supplies 110 to 120 volts AC to match the coil specification. Ensure the application requires exactly four main poles and does not need built-in auxiliary contacts or a reversing function, as this model provides neither feature.

Questions about this item

What coil voltage does the SIEMENS 3RT25171AK60 contactor require?

The coil is rated for 110-120V AC, so it must be powered from a control circuit within that voltage range.

What mounting options and overall dimensions does this contactor have?

It fits on a DIN rail or can be surface-mounted, measuring 3.08 in tall by 1.97 in wide in the S00 frame size.

How are the power and control wires connected, and what is a common installation mistake?

All connections use screw terminals; a frequent error is leaving the terminal screws loose, which can cause overheating under load.
