Product details

For reference, the ComPacT NSX family also offers S (36 kA), H (70 kA), and L (150 kA) breaking capacity codes at that voltage. At 480 V AC the rating holds at 50 kA (UL 60947-4-1), at 600 V it drops to 15 kA. The electrical durability at 440 V In is 10,000 cycles, 20,000 cycles mechanical — consistent with a distribution-duty breaker, not a switching device cycled daily.

Mounts to a backplate — not DIN rail. Connection pitch is 35 mm, standard for busbar or cable lug termination. IP40 enclosure protection, IK07 impact resistance. The toggle control type is panel-mountable; the breaker occupies five slot positions in a typical switchboard.

Thermal characteristics and derating

Rated 200 A at 40°C ambient. The TM-D trip unit is thermal-magnetic — the thermal bimetal is calibrated for the 40°C reference; above that, derate per the manufacturer's curve. Power dissipation per pole is 15.4 W, so total dissipation across three poles is about 46 W at rated load — factor that into enclosure heat rise calculations. The breaker operates up to 2000 m altitude without derating; above that up to 5000 m with derating. Relative humidity range 0-95%.

Frequently asked questions

What is the breaking capacity of C25N3TM200 at 415 V?

50 kA Icu at 380/415 V AC 50/60 Hz conforming to IEC 60947-2. That is the N breaking capacity class. At 480 V AC it also holds 50 kA (UL 60947-4-1); at 600 V AC it drops to 15 kA.

What is the closest alternative to C25N3TM200 in the same family?

Within the ComPacT NSX250 frame, the main alternative is the version with an electronic Micrologic trip unit instead of the TM-D thermal-magnetic. The TM-D is the fixed thermal-magnetic type; Micrologic offers adjustable long-time, short-time, and ground-fault protection. For a direct drop-in replacement with the same 200 A rating and N breaking capacity, the order code changes to reflect the trip unit variant.

Where can I buy C25N3TM200 and how is it quoted?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or lead-time figure is published here.

What standards does C25N3TM200 comply with?

Designed and tested to EN/IEC 60947-2 for circuit-breaker performance. Suitable for isolation per that standard. UL 60947-4-1 ratings also listed for 240 V, 480 V, and 600 V AC. Pollution degree 3 per IEC 60664-1, overvoltage category III.
