Molded Case Circuit-Breakers

Circuit breakers for distribution:

Thermal and magnetic protection for electric circuits in general; setting of the short circuit protection from 5 to 10 times the circuit breaker rated current, with tripping curve according to the criteria of IEC 60947-2 standard

Circuit breakers for motors:

Magnetic protection only. The short circuit tripping curve is set from 7.5 to 15 times the circuit breaker. Such setting allows starting the motor without premature trip of the protection system.

Circuit breakers for generators:

The protection against short circuit is set to trip up to 5 times the circuit breaker rated current, protecting the generator against current surges that may damage the electronics and compromise its regulation
