How does a 3 phase breaker work
WebLets find the correct size of circuit breaker for three phase circuits as follow. Example 1: Which size circuit breaker is needed for 6.5kW, three phase 480V load? Solution: Power in Three Phase: P = V x I x √3 Current: P / V x √3 I = 6.5kW / (480V x 1.732) … (√3 = 1.732) I = 6.5kW / 831.36 I = 7.82A The recommended size of circuit breaker is
