Ferraz Shawmut AJT45 Molded Case Circuit Breaker

Ferraz Shawmut AJT45 Molded Case Circuit Breaker is a 45 A, 600 V overcurrent protection device designed for electrical distribution equipment. The AJT45 model belongs to Ferraz Shawmut’s molded case breaker family and carries Class J characteristics, defining its trip behavior for protecting circuits from overloads and short circuits within systems up to 600 volts. Molded case breakers of this type typically use a thermal-magnetic trip mechanism to provide reliable protection and are designed for installation in standard electrical enclosures within commercial and light-industrial installations. With a 45 A rating, this device protects feeders and branch circuits from overcurrent up to its maximum voltage rating, helping to prevent electrical damage and downtime in systems that operate at or below 600 V.
