Cost of 3 phase circuit breaker

The cost of a 3-phase circuit breaker can vary widely depending on several factors, including:

1. Voltage rating: The voltage rating of the circuit breaker, which can range from 208V to 480V or higher.
2. Current rating: The maximum current the circuit breaker can handle, which can range from a few amps to several hundred amps.
3. Type: There are different types of 3-phase circuit breakers, including:
   • Molded case circuit breakers (MCCBs)
   • Air circuit breakers (ACBs)
   • Vacuum circuit breakers (VCBs)
   • Sulphur hexafluoride (SF6) circuit breakers
   • Arc-resistant circuit breakers
4. Brand and quality: The cost of a circuit breaker can vary depending on the brand and quality of the product.
5. Features: Some circuit breakers may have additional features such as:
   • Trip-free mechanism
   • Instantaneous trip
   • Time-delay trip
   • Ground fault protection
   • Arc fault protection

Here are some approximate cost ranges for new 3-phase circuit breakers:

• Molded case circuit breakers (MCCBs):
  • 208V, 15-30A: $50-$200
  • 208V, 30-60A: $100-$400
  • 208V, 60-100A: $200-$600
  • 480V, 15-30A: $100-$300
  • 480V, 30-60A: $200-$500
• Air circuit breakers (ACBs):
  • 208V, 15-30A: $100-$300
  • 208V, 30-60A: $200-$500
  • 208V, 60-100A: $300-$700
  • 480V, 15-30A: $200-$500
  • 480V, 30-60A: $400-$800
• Vacuum circuit breakers (VCBs):
  • 208V, 15-30A: $200-$500
  • 208V, 30-60A: $400-$800
  • 208V, 60-100A: $600-$1,200
  • 480V, 15-30A: $400-$800
  • 480V, 30-60A: $800-$1,600
• Sulphur hexafluoride (SF6) circuit breakers:
  • 208V, 15-30A: $500-$1,000
  • 208V, 30-60A: $1,000-$2,000
  • 208V, 60-100A: $1,500-$3,000
  • 480V, 15-30A: $1,000-$2,000
  • 480V, 30-60A: $2,000-$4,000

Please note that these are approximate cost ranges and the actual cost of a 3-phase circuit breaker can vary depending on the specific product and brand you choose. It's also important to consider the cost of installation, maintenance, and replacement when selecting a circuit breaker.
