Product details

It carries 5 normally open instantaneous contacts, each rated 10 A at 24 V, with a full voltage ladder from 24 V through 690 V AC/DC.

The S00 frame is 45 mm wide, 57.5 mm tall, 117 mm deep — a standard footprint that shares the same cutout as the 3RH2 contactor range.

Contact ratings and switching performance

The 5 NO contacts are rated for AC and DC loads across the voltage range: 10 A at 24 V, 6 A at 230 V AC, 3 A at 400 V AC, 1 A at 690 V AC. DC ratings drop with voltage: 4.7 A at 60 V, 1.2 A at 220 V, 0.5 A at 440 V, 0.26 A at 600 V. Switching frequency for DC loads is 10,000 operations per hour. AC switching time is 4 to 15 ms. The coil operates at 50 Hz (0.8 to 1.1 x rated voltage) and 60 Hz (0.85 to 1.1 x rated voltage).

Wire connection accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded.

Frequently asked questions

Who supplies 3RH2353-1CF00-0KA0 and how is it quoted for volume purchases?

This part is sourced through independent distribution channels and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time — submit a request with your target quantity and delivery window.

What is 3RH2353-1CF00-0KA0's listed depth?

The listed depth is 117 mm. Combined with a width of 45 mm and height of 57.5 mm, it fits the standard S00 contactor footprint on 35 mm DIN rail.

What compliance documentation does this brand provide for 3RH2353-1CF00-0KA0?

The part carries RoHS compliance with a substance prohibition date of July 1, 2006. Pollution degree 3 is specified for industrial environments. Standard Siemens SIRIUS documentation includes the declaration of conformity and technical data sheet.

Will 3RH2353-1CF00-0KA0 drop into a panel specified around 3RH2362-2AF00 without rewiring?

Both are S00 frame auxiliary contactors with the same 45 mm width and DIN-rail snap-on mounting. The 3RH2353-1CF00-0KA0 carries 5 NO contacts, while the 3RH2362-2AF00 has a different contact configuration (typically 4 NO + 1 NC). Terminal layout and wire sizes are identical, so a panel swap is mechanical — no rewiring needed if the contact count matches your circuit.
