Product details

The 480 V rating of 96 A is the AC-3 duty current—this is the motor-switching rating, not the resistive-heat rating. AC-3 means it makes and breaks motor loads at full current; the contactor is designed for that inrush. The AC-1 (resistive) switching frequency is 900 operations per hour, while AC-3 allows 850 1/h. If your application cycles faster than that, you'll need to derate or step up to a larger frame. That's the mechanism life before wear-out, not the electrical contact life under load. Electrical life depends on the switching current and frequency; the datasheet curve (not reproduced here) governs that. The main contact configuration is 10 normally open contacts, with 2 auxiliary contacts—verify your circuit count against that.

Wiring and Termination Reality

The main circuit accepts stranded wire from 6 to 70 mm²—that's a wide range covering #10 AWG up to #2/0 AWG roughly. Solid wire for the main circuit is listed at 2.5 to 16 mm². That means the contactor can handle both fine-stranded power cabling and solid control wiring without adapters. Physical dimensions: 70 mm wide, 140 mm high, 195 mm deep. The S3 frame is a common size; if you're replacing an existing S3 contactor, the mounting hole pattern and rail footprint should match.

Frequently asked questions

What is the listed depth?

The depth is 195 mm. This is the body depth including terminals; allow extra clearance for cable bending.

What solid wire range does the main circuit accept?

Solid wire from 2.5 to 16 mm² is accepted on the main circuit terminals.

What compliance documentation is available?

As a Siemens SIRIUS product, it typically carries CE, UL, CSA, and CCC certifications. RoHS and REACH compliance documentation is standard for current-production Siemens industrial controls. Specific cert numbers should be confirmed from the product marking or Siemens' official documentation portal.
