How to Select BYSON RCBO?

Choosing the right BYSON RCBO (Residual Current Circuit Breaker with Overcurrent Protection) requires consideration of parameters, application requirements, safety standards, and brand-specific features. Below is a step-by-step guide to help you make the best selection.

Electrical Parameters:

1. Rated Current:

   • Based on the circuit load: 1A, 2A, 3A, 4A, 5A, 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A.

   • Should be slighterly higher than the needed operating current.

2. Poles Number:

   • 1P+N
   • 2P
   • 3P
   • 3P+N
   • 4P

3. Residual Operating Current:

   • 30mA: electric shock protection (e.g., residential).

   • 100mA, 300mA: fire protection (e.g., industrial).

4. Breaking Capacity:

   • 3kA

   • 4.5kA

   • 6kA

Verify Compliance & Certifications:

Ensure the BYSON RCBO meets:

• IEC 61009-1 (RCBO standard).

• Regional certifications: CE, CCC
