Designed for railway applications (per the product designation), it also fits general mechanical engineering and industrial panel duty.
D-curve and breaking capacity
The D characteristic trips magnetically at 10 to 20 times rated current (60–120 A for this 6 A unit), so it handles the inrush of motor loads, transformers, or solenoid banks without nuisance tripping.
Mount in any position, and the supply cord can enter from either end. The 76 mm overall depth leaves clearance for a standard 80 mm deep enclosure.
No neutral pole switching — this is a 3P breaker for three-phase loads only. The 5SY4CC11 design variant is the specific internal construction for this order code.
