Product details

DC distribution breaker, 500 A thermal-magnetic

The C63F3TM500D is a Schneider Electric ComPacT NSX DC fixed-mount circuit breaker, 3-pole (3D protected), rated 500 A at 40 °C with a thermal-magnetic TM-DC trip unit providing LI protection (thermal overload L, magnetic short-circuit I). Breaking capacity hits 36 kA Icu per IEC 60947-2 across the DC voltage range: 24…125 V DC 1 pole, 250 V DC 1 pole, 500 V DC 2 poles in series, and 750 V DC 3 poles in series — so the same frame covers low-voltage battery banks up to 750 V DC distribution. Rated insulation voltage is 750 V DC, and the breaker is certified for isolation (EN/IEC 60947-2), meaning it can serve as a visible disconnect in a DC bus.

Fixed backplate mount, 140 mm wide, 255 mm tall, 110 mm deep — horizontal or vertical orientation on the backplate, front connections both top and bottom. Toggle control, 6 auxiliary contact slots available for alarm or status feedback.

Frequently asked questions

What is the breaking capacity of C63F3TM500D?

36 kA Icu per IEC 60947-2 at 24…125 V DC 1 pole, 250 V DC 1 pole, 500 V DC 2 poles in series, and 750 V DC 3 poles in series.

What standards does C63F3TM500D comply with?

EN/IEC 60947-2 for circuit breakers, IEC 60664-1 for pollution degree 3, IEC 62262 for IK07 impact, IEC 60529 for IP40 ingress protection.

What is the closest alternative to C63F3TM500D in the ComPacT family?

Within the ComPacT NSX DC range, the closest sibling would share the same NSX630F DC frame but differ in trip rating or poles. No pin-compatible direct drop-in exists without verifying the trip unit and pole configuration against your BOM.
