Product details

It is a 4-pole device (4P) with a breaking capacity of 25 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2 — that is the fault current it can safely interrupt at typical three-phase distribution voltages without welding contacts or venting plasma. For higher fault levels, the NSX family offers S (36 kA) and H (50 kA) variants, but for a typical 415 V line feeding motor control centers or lighting panels, the B rating covers the majority of installations.

The toggle control and front-facing connections (upside and downside) simplify wiring in a distribution board. IP40 front face keeps tools and fingers out; IK07 impact resistance handles incidental knocks during commissioning.

Frequently asked questions

What is the breaking capacity of C10B4TM080C at 415 V?

25 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2. At 440 V it drops to 20 kA Icu; at 500 V to 15 kA Icu.

Where can I buy C10B4TM080C and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock or price figures are published here.

What compliance documentation does Schneider provide for C10B4TM080C?

The MCCB is certified to EN/IEC 60947-2 and carries suitability for isolation per that standard. Pollution degree 3 per IEC 60664-1. The manufacturer typically provides a Declaration of Performance and CE/UKCA marking; specific RoHS/REACH declarations are available on request from the distributor.
