Product details

The 3-pole design (3P) switches all three phases simultaneously, making it suitable for three-phase loads like small motors, pumps, or lighting circuits in a panel.

IP20 protection with connected conductors; fine for dry indoor panels, not for washdown zones.

Thermal derating and environment

Rated 63 A at 35 °C; derates to 60.04 A at 40 °C, 58.46 A at 45 °C, 56.89 A at 50 °C, and 53.55 A at 60 °C — factor this into your load calculation if the panel runs warm. Operates from -40 °C to 75 °C ambient, with humidity limits of 95% up to 55 °C, 55% up to 70 °C, and 35% up to 75 °C — covers most indoor industrial environments.
