The thermal adjustable circuit breakers and electronic circuit breakers are smaller.
250AF circuit breakers’ fixed types (NF250-CV, NF250-SV, NF250-HV, NV250-CV, NV250-SV, NV250-HV), thermal adjustable types
(NF250-SGV, NF250-HGV, NF250-RGV), and electronic types (NF250-SEV, NF250-HEV, NV250-SEV, NV250-HEV) are the same size,
leading to the reduction and standardization of panel design.
