Circuit Breaker FAQs

Find quick answers to common questions about selecting and using industrial circuit breakers.

A circuit breaker automatically interrupts the flow of electricity when it detects an overload, short circuit, or fault condition. This protects wiring, equipment, and personnel from electrical hazards and prevents costly damage to industrial systems.

Choosing the correct circuit breaker depends on several factors:

  • Load size and type (motor, lighting, HVAC, etc.)
  • Voltage rating (low voltage, medium voltage)
  • Interrupt rating (ability to handle fault currents)
  • Application environment (indoor, outdoor, corrosive conditions). Wistex’s technical team can assist you in selecting the best circuit breaker for your specific needs.

Motor circuit breakers are specially designed to handle the high inrush currents typical during motor startup. They provide both overload and short-circuit protection tailored for motors. Standard circuit breakers are used for general electrical circuits, such as panelboards and lighting, where the startup current is lower and more consistent.
