The Schneider GoPact G12T4A50 is a 4-pole molded-case circuit breaker rated 50 A at 40 °C, with a 10 kA breaking capacity at 415 V AC — enough for distribution panels feeding motor control centres or lighting sub-distribution in commercial and light industrial buildings. That LI combination covers the majority of cable and load protection needs without the adjustability of an electronic trip. It is listed as current-production (lifecycle stage: current), so no last-time-buy scramble — this is a standard catalogue item you can specify into a new BOM.
The 25 mm pole pitch keeps the footprint compact for a 4P breaker. Neutral is on the left, and the 4D protected-poles configuration means all four poles (including neutral) are switched and protected.
Coordination and duty
Rated for utilisation category A, meaning it is not intended for frequent switching of motor starts — it is a distribution breaker, not a motor-starter combination. Use it upstream of contactors or as a main panel breaker. Electrical durability is 8000 cycles at rated current, mechanical durability 30 000 cycles — typical for a distribution MCCB; expect it to outlast the panel if not cycled daily.
Standards and environment
Altitude rating is 0–2000 m without derating, 2000–5000 m with derating — check the thermal curve if installing above 2000 m.
