Title:
極毎の電流検出装置を備えた多極低電圧遮断器
Document Type and Number:
Japanese Patent JP4683809
Kind Code:
B2
Abstract:
A current measuring device (15) for a multi-pole low voltage circuit breaker (1). comprises a support body (20) with a through opening for a current conductor (4) for each of the poles and a receiving chamber (22), surrounding the through opening (21), for secondary components (26, 31) of current sensors and/or current transformers. The support body (20) is essentially plate-like and rectangular and forms part of the rear wall (13) of the circuit breaker (1). Should Rogowski coils (26) be used as secondary components of a transformer, then adjustable voltage dividers are also mounted on the support body for interdependent adjustment. The multi-pole current measuring device (15) simplifies the production of circuit breakers as approved components.
