Product details

The Schneider Electric G12F3F63 is a GoPact MCCB 125 — a 3-pole molded-case circuit breaker with a TM-D thermal-magnetic trip unit rated 63 A at 40 °C. It's designed for distribution duty in fixed-mount backplate panels, with front-facing screw terminals for both line and load connections.

The 8000 electrical cycles at rated current and 415 V cover frequent switching in distribution, while the 30,000 mechanical cycles give a long service life for the mechanism. At 18.7 W dissipation per pole, total heat load for the 3-pole breaker is about 56 W at rated current. That's a real number for enclosure thermal calculations — don't forget to sum it with adjacent devices when sizing ventilation or forced cooling.
