Low-voltage switching device e.g. residual current circuit breaker has clamping spring that includes clamping leg whose distal end contacting free end of connecting conductor is electrically insulated

摘要

The low-voltage switchgear has a clamping frame (10) that is formed by connecting the connection legs (222,224) and auxiliary leg (114). A terminal connection space (18) is formed between the legs and a clamping portion (120) of the auxiliary leg is arranged with respect to connecting web (112) of clamping spring (12) to clamp free end (15) of a connecting conductor (14) between clamping portion and clamping leg (216) of spring. The distal end of the clamping leg contacting free end of the conductor is electrically insulated.
