Product details

The TM-DC trip unit provides L (thermal overload) and I (magnetic short-circuit) protection.

DC application and deployment context

Rated insulation voltage 750 V DC per IEC 60947-2. The 4-pole configuration with 4 protected poles (4D) and left-side neutral position suits ungrounded or bipolar DC systems. Mounts fixed to a backplate; horizontal or vertical orientation accepted. IP40 enclosure protection means it's for clean, dry panel interiors — not outdoor or washdown zones.

Suitability for isolation confirmed per that standard — the breaker provides visible break and meets touch-safe isolation requirements. No earth-leakage protection integrated; specify an external RCD or Vigi module if ground-fault detection is needed.

Frequently asked questions

What is C63F4TM500D's breaking capacity at 750 V DC?

36 kA Icu at 750 V DC with 3 poles in series per IEC 60947-2. The same 36 kA rating applies at 24-125 V DC (1 pole), 250 V DC (1 pole), and 500 V DC (2 poles in series).
