IEC Magnetic Contactor 4-Pole 9A
The SIEMENS 3RT25161AK60 is a new IEC magnetic contactor built for DIN-rail or surface mounting in control panels. It suits machine builders and maintenance teams who need a compact S00-frame device for switching motor loads up to 9 A inductive or 18 A resistive. No auxiliary contacts are included.
Screw Terminals No Auxiliary Contacts
Screw terminals accept solid or stranded conductors without special tooling. The absence of auxiliary contacts means the unit provides only the four main power poles; signalling or interlock circuits require a separate accessory block. The coil operates on 110/120 V AC for direct connection to standard control transformers.
9A Inductive 18A Resistive Headroom
Rated at 9 A inductive and 18 A resistive, the contactor handles small motor starters, heating elements and lighting circuits within the S00 frame. Loads exceeding 9 A inductive will saturate the contacts, so larger frame sizes must be specified for higher motor currents. The 2.4 in height and 1.95 in width fit tight panel layouts.

Questions about this item
How often do the screw terminals on the SIRIUS 3RT25 frame need retightening under normal vibration?
Periodic inspection of the screw terminals is recommended; retighten if vibration loosens connections, following standard maintenance schedules for DIN-rail contactors.
Which rating — the 9 A inductive or the 18 A resistive full-load current — is reached first during continuous motor starting?
The 9 A inductive full-load current limit applies to motor loads and will be reached before the 18 A resistive rating during sustained starting cycles.
Does the coil draw enough power at 110-120 V AC to raise cabinet temperature noticeably during all-day operation?
The coil is rated for 110/120 V AC; typical sealed power is low, so temperature rise inside the enclosure is minimal during continuous duty.
