Product details

The C10F1TM020 is a 1-pole ComPacT NSX100F thermal-magnetic circuit breaker rated 20 A at 40 °C, built to EN/IEC 60947-2 for distribution duty. The TM-D trip unit gives you L (thermal overload) and I (magnetic short-circuit) protection in one compact fixed-mount package — no earth-leakage module on this variant.

Fixed backplate mount, 35 mm width per pole, 161 mm tall, 86 mm deep.

20 A continuous at 40 °C ambient. 18 kA breaking capacity at 240 V AC, 36 kA at 250 V DC. 20000 mechanical cycles, 20000 electrical cycles at rated current. Power dissipation 4.01 W per pole. Overvoltage category IV — suitable for main distribution boards. Operating altitude 0–2000 m without derating, up to 5000 m with derating.

Frequently asked questions

What is C10F1TM020's breaking capacity?

18 kA Icu at 220/240 V AC 50/60 Hz per IEC 60947-2, and 36 kA Icu at 250 V DC per the same standard.

What trip unit does C10F1TM020 use?

A TM-D thermal-magnetic trip unit, rated 20 A at 40 °C. The L protection handles overloads (thermal), the I protection handles short-circuits (magnetic). No earth-leakage function on this variant.

Where can I buy C10F1TM020 and how is it quoted?

Sourced through independent distribution channels. Quoted to order against an RFQ — availability and current pricing confirmed at quote time. No minimum volume commitment required for a quote.

What compliance documentation does Schneider provide for C10F1TM020?

The breaker is certified to EN/IEC 60947-2, carries IP40 per IEC 60529, IK07 per IEC 62262, and is rated for pollution degree 3 per IEC 60664-1 and overvoltage category IV. Standard manufacturer declarations for CE/UKCA marking apply.
