Product details

Temperature derating and mounting

The 6 A rating holds at 35 °C ambient; above that the breaker must be derated: 5.55 A at 40 °C, 5.31 A at 45 °C, 5.06 A at 50 °C, 4.79 A at 55 °C, and 4.51 A at 60 °C. If your panel ambient runs at 50 °C, plan for a 5 A load ceiling on this pole pair. It occupies 2 modular width units (36 mm wide, 90 mm tall, 76 mm deep, 70 mm installation depth).

The 2-pole design switches both lines in a DC circuit — no neutral conductor switching.
