WebIn other words, a load circuit having 24A, the appropriate size of breaker would be: 24A / 0.8 = 30A. An exact 100% rated for 30A circuit breaker can be used for 30A non-continuous load. In case of continuous load, rate of %125 is applicable. Example 3: CB Size for 30A Non-contentious Load & 28A contentious Load. WebNote: For circuit-breakers equipped with non-adjustable overcurrent-trip relays, Ir = In. Over current protection time setting (tr): It is denoted by tr. In this dial, we set the time limit for the over current protection as we said above. In our case we have set 0.5 sec. It means, the MCCB allows 320+ Amps for just 0.5 sec only.
