3-in-1 Current Transformers TASN Series
SKU: TASN-240-150/5A range of 3-in-1 current transformers combine three Traditional current transformers in one moulded case. 3-in-1 current transformers can be directly installed next to a three-phase moulded case circuit breaker, thus saving installation time where fitting three standard individual current transformers would be required. The 3-in-1 Range of current transformers primary currents between 60A~630A with 5A or 1A secondaries with up to Class 0.5 accuracy performance
