This is a three-pole breaker (3P) with front connections both top and bottom, mounting flat on a backplate.
Selectivity and coordination context
The 50,000 electrical cycles at 440 V In and 20,000 at 690 V In/2 give a realistic endurance figure for motor feeder or distribution duty — not a one-time-only device. Mechanical durability of 50,000 cycles matches the electrical endurance at lower loads. Category A utilization means it's not specifically designed for motor starting with high inrush; it's a distribution breaker, though it handles general-purpose loads fine.
Installation notes
Mounts flat on a backplate in any orientation (horizontal or vertical). IP40 front face protection keeps dust and small tools out; IK07 impact resistance handles incidental contact in the panel.
