SIEMENS

SIEMENS 3RT25161AB00 24VAC Magnetic Contactor 4P 9A relay

SKU CH-AN8Z-W4H8T

A 4-pole IEC magnetic contactor rated 9 A inductive and 16 A resistive with a 24 VAC coil for motor loads up to 5 hp at 480 V three-phase

  • 4-pole contactor for multi-circuit control
  • 24 V AC coil fits low-voltage panels
  • 9 A inductive rating handles motor loads
  • 50/60 Hz operation suits global supplies
  • Compact 1.77 in footprint saves panel space

24V AC 4-pole contactor

The SIEMENS 3RT25161AB00 is a non-reversing IEC magnetic contactor rated for 9 A inductive and 16 A resistive loads. It suits control panels and motor-start circuits that require four poles in a compact S00 frame. The 24 V AC coil operates on 50 or 60 Hz supplies. This unit is sold new and carries CSA, IEC and UL markings.

Sustained load behaviour

At continuous duty the main contacts handle up to 9 A inductive or 16 A resistive current without derating. Horsepower ratings are 1/3 hp at 120 V single-phase, 1 hp at 240 V single-phase, 3 hp at 240 V three-phase and 5 hp at 480 V three-phase. The open-frame design relies on cabinet airflow for cooling during prolonged operation.

Installation notes

The contactor measures 1.77 in high, 1.77 in wide and 2.87 in deep, fitting standard DIN-rail or screw mounting. Wiring must follow the 2NC/2NO main contact configuration shown on the nameplate. Common errors include reversing the coil connections or exceeding the 24 V AC coil voltage, which causes overheating.

Questions about this item

How much heat does the 9 A inductive load generate during continuous operation?

The contactor handles 9 A inductive and 16 A resistive loads at 24 V AC coil voltage without a specified thermal rating in the data.

What wiring and mounting hardware must I already have to install the S00 frame contactor?

You need 24 V AC control wiring, power conductors rated for up to 16 A resistive, and a panel cut-out matching the 1.77 in by 1.77 in footprint.

Will the 4-pole 2NC/2NO main contacts work with my existing 120 V single-phase motor starter?

Yes, the contactor is rated 1/3 hp at 120 V single-phase and 1 hp at 240 V single-phase, matching typical motor-starter coils.
