Product details

This 4-pole fixed-mount breaker (4D protected poles) is designed for DC distribution applications, with front connections on both line and load sides.

The 600 A trip rating at 40 °C sets the continuous current-carrying capacity; above 40 °C, derate per the thermal curve. The rated insulation voltage of 750 V DC confirms the internal clearances and creepage are designed for DC bus voltages up to that level.

Fixed backplate mount, 185 mm wide, 255 mm high, 110 mm deep. Horizontal or vertical orientation, flat on the back. Front connections on both sides — plan for top-entry line and bottom-entry load cabling. The 45 mm connection pitch matches standard busbar or cable-lug spacing for 600 A class.

Frequently asked questions
