Product details

Integrator note — SIRIUS 3RH2344-2AP00-0KA0

The Siemens SIRIUS 3RH2344-2AP00-0KA0 is a size S00 auxiliary contactor with 4 normally open (NO) instantaneous contacts, rated for a 230 V AC coil at both 50 Hz and 60 Hz. The coil holds across 0.8 to 1.1 times rated voltage at 50 Hz, 0.85 to 1.1 at 60 Hz; dropout below that range is clean, which matters for safety-circuit interlocking where a held-in contactor is a hazard.

Rated currents and switching capability

The 4 NO contacts carry 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — these are thermal current ratings for the contact block, not motor-starting duty. For DC switching, the same contacts handle 4.7 A at 60 V, dropping to 0.26 A at 600 V.

Frequently asked questions

What are the key ratings of the 3RH2344-2AP00-0KA0?

It is a size S00 auxiliary contactor with 4 NO contacts, a 230 V AC 50/60 Hz coil, rated 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V. Mechanical endurance is 10 million cycles.

What is the width and depth of the 3RH2344-2AP00-0KA0?

Width is 45 mm, depth is 121 mm, height is 70 mm — the S00 frame size.

Will 3RH2344-2AP00-0KA0 fit in a panel wired for 3RH2362-2AF00?

Both are S00 frame contactors on 35 mm DIN rail with the same 45 mm width and 121 mm depth footprint, so the mechanical fit and wiring clearance are identical. The difference is contact configuration — this one has 4 NO, while the 3RH2362-2AF00 has a different contact arrangement — so verify the control circuit schematic before substitution.

Where can I buy 3RH2344-2AP00-0KA0 and get current pricing?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What compliance documentation does the 3RH2344-2AP00-0KA0 carry?

RoHS compliance is documented with a substance prohibition date of October 2009. As a SIRIUS product, it carries CE marking and is designed to IEC 60947-5-1. UL and CSA file numbers are available through the standard Siemens documentation channel.
