140G-N6K3-E12 | Circuit Breaker

The 140G-N6K3-E12 Molded Case Circuit Breaker has a N Frame and 1200 Amps. It also has a 60 kA Interrupting Rating and 3 Poles.• Magnetic and thermal trip currents may be fixed or adjustable• Must be sized per NEC/CEC rules• May be used for motor circuits, but 140MG (MCP) is first choice• Motor Current (thermal rating)– ≤ 250% motor full load amperes (FLA)– ≤ 300% for motors ≤ 100 A if the circuit trips on start– ≤ 400% for motors ≥ 100 A if the circuit breaker trips on start• Magnetic trip current is generally set at 1000% (10x) of circuit breaker thermal ratings• May be UL Listed as part of UL 508/UL 60947-4-1• May also be used for motor control-circuit transformers, but Bulletin 1489 miniature circuit breakers (MCBs) are a moreappropriate choice
