(A) MCB 1P 4A C CURVE 277VAC US/230VAC I

Allen-Bradley, Rockwell Automation 1492-SPM Circuit breaker protects your electrical supply from current overloads. When a surge in current reaches the maximum allowance of 10kA, the MCB is thermo-magnetically tripped to stop a short circuit that could otherwise damage the wires.

1492-SPM MCB have type C tripping curve and fast breaking time to provide a higher level of safety for your application. 1492-SPM MCB include screw terminals, are IP20 finger safe, and can be DIN rail mounted for optimal convenience. 1492-SPM MCB have dual terminals for wiring and bus bar flexibility and have excellent shock and vibration resistance which helps to prevent nuisance tripping, avoiding unnecessary downtime.

Type C Miniature Circuit Breaker are suitable for use in commercial and light industrial applications, such as fluorescent lighting and small electric motors, and are designed to trip at currents between five and ten times their rated load.
