## Discrepancy

DURING CLIMB AS THE LEFT ENGINE ANTI-ICE WAS SELECTED, THE CIRCUIT BREAKER TRIPPED.  CREW FOLLOWED THE COCKPIT OPERATING MANUAL PROCEDURES AND THE BREAKER TRIPPED AGAIN.  AIRCRAFT RETURNED TO MSP AND LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE REPLACED THE LEFT ENGINE ANTI-ICE VALVE, OPERATIONAL CHECK OK.
