The LTB E is a high performance circuit breaker intended for full breaking current up to 50 KA with a rated voltage from 72.5 KV up to 800 KV. The LTB E is offered for solo or three pole process. The energy required to interject the current is engaged from the arc itself, which decreases mechanical pressure on the circuit breaker and upsurges the network dependability. Entirely the LTB E circuit breakers use a spring drive working device to safeguard the uppermost network dependability. ABB can offer the LTB 800E4 with one working device per phase, since the high energy BLG spring drive is the utmost influential on the market.
