Product details

What the 1000 A AC-23A rating means for your line

AC-23A per IEC 60947-3 covers switching of motor loads and other highly inductive circuits, so this 1000 A figure is the current it can make and break under those conditions, not just carry.

Withdrawable frame — panel integration note

The drawout (withdrawable) mounting means the switching element can be racked out for maintenance or replacement without disturbing the fixed connections. Front connections top and bottom, 70 mm connection pitch. Panel cutout and busbar spacing need to accommodate the 327 mm width and 210 mm height; depth is 147 mm behind the panel face. IP40 enclosure protection, IK07 impact resistance — fine for indoor switchgear, not for washdown.

Withstand and isolation capability

Rated short-time withstand current (Icw) is 25 kA for 0.5 s, with a short-circuit making capacity (Icm) of 52 kA at 690 V. That tells you the frame can survive a fault long enough for an upstream breaker to clear, and it can close onto a bolted fault without welding contacts. The unit is suitability-for-isolation marked per IEC 60947-3, so it qualifies as a visible-break disconnect for lockout/tagout. Rated impulse withstand voltage (Uimp) is 8 kV, pollution degree 3.

Frequently asked questions

What is the closest alternative to C100S3WM in the ComPacT NS family?

The C100S3WM is a basic frame (no visible break indicator, front connections). The closest functional sibling would be a fixed-mount version if you don't need drawout capability, or a version with a visible-break option if your safety procedure requires a positive gap indication. The key differentiator is the drawout mechanism — if you don't need rack-out capability, a fixed version saves panel depth.

What compliance documentation does Schneider provide for C100S3WM?

The C100S3WM is designed and tested to IEC 60947-3. Standard documentation includes the IEC declaration of conformity. RoHS and REACH compliance status is available on request from Schneider Electric's documentation portal.

Where can I buy C100S3WM and how is it quoted?

The C100S3WM is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
