How to Select the Right Manufacturer
Assess Needs
To pick the right manufacturer of air circuit breakers, you must know what your project needs. Every job is different. Factories might need breakers that handle more current and have special trip features. Offices or stores often want smaller breakers that are easy to put in. Always check if the breaker’s current rating and fault interrupting capacity match your system. Make sure it works with your switchgear. Things like heat, shaking, and wetness can change how well a breaker works. If you pick a breaker that is too big or the wrong kind, you might spend too much or not get good protection. Try not to make these mistakes:
- Using the wrong breaker for your project
- Forgetting about the place and how it is used
- Picking a breaker with too much interrupting power
- Getting the wrong terminal or actuator
