Product details

Designed for railway applications and rated universal current, it handles both AC and DC loads. On DC the rated voltage is 220 V; on AC the supply can be connected from either side as long as DC polarity is observed.

Mountable in any position. IP20 with connected conductors — suitable for enclosed panel environments, not washdown zones.

Thermal derating and sourcing posture

Rated 6 A at 35 °C, the breaker derates to 5.63 A at 40 °C, 5.44 A at 45 °C, 5.24 A at 50 °C, 5.04 A at 55 °C, and 4.82 A at 60 °C (–).
