Gossen Metrawatt GTZ3512000R0001 - Current Transformer Clamp (0.5 to 1000 A ac)
The current transformers serve to expand AC measuring ranges. In conjunction with indicating and recording instruments, it is possible to measure AC currents on lines and bus bars without the need to interrupt them. The secondary connection is made via hard-wired leads with contact-protected connection plugs. A protective circuit prevents high voltages when the secondary circuit is interrupted.
