The LTB D or also known as Live Tank Circuit Breakers is a high performance circuit breaker designed for extreme breaking current up to 40 KA with a appraised voltage from 72.5 KV up to 170 KV. The LTB D is offered for solo or three pole process. The energy requisite to interject the current is taken from the arc itself, which decreases mechanical stress on the circuit breaker and upsurges the network dependability. All the LTB D circuit breakers use coil drive functioning mechanism to safeguard the uppermost network reliability. As a substitute for applications that need daily operations. ABB can also run the digital precise Motor Drive. To safeguard a safe and simple ordering, the LTB D is partly preassigned and tested in our factory.
