What is a 3P+N RCBO?
A 3P+N RCBO is a residual current circuit breaker with overcurrent protection intended for a three-phase system with a neutral conductor. It combines residual current protection with overload and short-circuit protection. On the ETL2-63(H) 3P+N, the neutral line is unswitched.
What is the difference between ETL2-63 and ETL2-63H?
The ETL2-63 has a rated short-circuit breaking capacity of 6kA, while the ETL2-63H has a rated short-circuit breaking capacity of 10kA.
Is the ETL2-63(H) 3P+N RCBO available in Type A?
Yes. The product series offers Type A and Type AC residual current detection. Please confirm the availability of your required specification before ordering.
Which tripping curves are available for the 3P+N version?
The 3P+N version offers B, C and D tripping curves. The appropriate curve depends on the load characteristics and installation requirements.
Does this RCBO switch the neutral?
No. The neutral line of the ETL2-63(H) 3P+N RCBO is unswitched. If neutral switching or isolation is required, select a device suitable for that requirement.
