ABB SN201-C20 – 1+N Miniature Circuit Breaker with Push-in Technology
With the ABB SNX201-C20, you rely on modern push-in technology for your 1+N circuit protection. The miniature circuit breaker provides a 20 A rated current and a 6 kA breaking capacity. Furthermore, its compact design ensures optimal space utilization in the distribution board.
Your Advantages at a Glance
-
Tool-free Wiring: The push-in terminals allow for quick and secure contacting – entirely without a screwdriver.
-
Space-saving: With 1 module (17.5 mm width), the SNX201-C20 fits even into compact distribution boards.
-
High Breaking Capacity: 6 kA rated breaking capacity according to EN 60898-1 for reliable short-circuit protection.
-
C Characteristic: Optimal for loads with higher inrush currents such as air conditioners or motors.
-
ABB Quality: Tested and approved according to international standards for worldwide use.
Areas of Application for the SNX201-C20
The C tripping characteristic trips at 5 to 10 times the rated current. Therefore, this circuit breaker is ideal for circuits with motors, compressors, or electronic equipment. Especially in small distribution boxes, the narrow design is impressive. That's why the circuit breaker is also a good choice for subsequent expansions.
