A User can use the GYM9-63DC circuit breaker for DC rated voltage to 1000V, rated current to 63A line, for overload and short circuit protection, and can also use it as an infrequent operation. They use Circuit breakers in DC applications such as communications and photovoltaic systems. Our Miniature Circuit Breakers (MCBS) is top of the line
The general rule of thumb is that circuit breaker size should be 125% of the ampacity of cable and wire or the circuit which has to be protected by the CB. Let see the following solved examples: Example 1: Suppose a 12-gauge wire is to be used for a 16-ampere lighting circuit with a 120V single-phase supply.
