FS360040A - 40Amp Circuit Breaker Description

FS360040A - 40Amp Circuit Breaker

When you’re maintaining existing electrical equipment, a replacement breaker needs to match more than the amp rating. The FS360040A is a 40-amp, 3-pole Type FS thermal-magnetic circuit breaker with a non-interchangeable trip unit and a 40°C rating. These breakers are built to last, while proper compatibility remains the key consideration. Before installation, compare the FS360040A with the existing breaker and equipment requirements, paying particular attention to amperage, number of poles, system voltage, A.I.C. rating, Type FS designation, thermal-magnetic operation, trip-unit configuration, physical dimensions, and terminals.

Key Features and Benefits

  • 40A rating: Matches equipment specifically requiring a 40-amp circuit breaker.
  • 3-pole configuration: Provides the specified arrangement for three-pole applications.
  • Thermal-magnetic operation: Maintains the specified operating configuration of the FS360040A.
  • Non-interchangeable trip unit: Preserves the specified Type FS breaker configuration.
  • 40°C rated: Provides another defined specification to check when matching the breaker to existing equipment.
  • Load terminals included: Matches the supplied configuration for this model.

Where It Works Best

The FS360040A is best considered for existing and legacy electrical equipment that specifically requires a 40A, 3-pole Type FS thermal-magnetic circuit breaker with a non-interchangeable trip unit. For replacement work, the physical footprint matters just as much as the electrical specifications. Confirm that the 4.13-inch width, 6.00-inch height, and 3.38-inch depth correspond to the breaker being replaced and the equipment requirements.
