Product details

The Schneider Electric C25B4TM200 is a ComPacT NSX250B moulded-case circuit breaker (MCCB) — 4 poles, 200 A rated current at 40 °C, fitted with a TM-D thermal-magnetic trip unit for overload (L) and short-circuit (I) protection per EN/IEC 60947-2.

Breaking capacity — the number that decides the bus fit

Rated 40 kA Icu at 240 V AC, 25 kA at 415 V, 20 kA at 440 V, and 15 kA at 500 V. The 25 kA figure at 415 V is the standard industrial distribution benchmark in IEC markets — if your fault-current study comes in under that, this breaker clears the fault without upstream coordination issues.

Trip unit and protection curve

TM-D trip unit: thermal element for overload (L) and fixed magnetic for short-circuit (I). Neutral protection is set at 1 x Ir (4D), meaning full-rated protection on the neutral pole for a 4-pole breaker in a distribution panel.

IP40 front face (IK07 impact rating) suits enclosed panel installation; the enclosure itself provides the required IP rating for the environment.

Frequently asked questions

What is the breaking capacity of C25B4TM200 at 415 V?

25 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2. That is the standard industrial distribution rating for this frame size.

Where can I buy C25B4TM200 and get current pricing?

Available to order through independent distribution. Submit an RFQ for current pricing and availability — confirmed at quote time, not from a static listing.

What compliance standards does C25B4TM200 meet?

Certified to EN/IEC 60947-2 for low-voltage switchgear. Pollution degree 3 per IEC 60664-1, overvoltage category III. Suitable for isolation per the same standard.
