Picking the right circuit breaker is key for smart building automation. Follow these steps:
1. Define the Scenario
Lighting: Calculate total wattage to choose a breaker (15 - 20A for small setups, higher for large spaces).
HVAC: Account for inrush current; a 30 - 50A breaker suits small - medium units.
EV Charging: Higher - rated breakers (30A +) handle EV charging demands.
2. Prioritize Smart Connectivity
Opt for breakers supporting Modbus/MQTT. They enable remote monitoring (current, voltage) and automation (e.g., peak - time disconnections). Simpower’s ARBI - 32 fits smart building needs.
3. Check Protection Rating
Indoor: IP40 protects from dust/small objects, ideal for offices.
Outdoor: IP65 resists dust and water, perfect for parking lots or charging stations.
4. Verify Certifications
Ensure CE (European) and local (e.g., GB/T) certifications for safety and compliance. Simpower meets these standards.
5. Evaluate Brand Service
Choose a brand like Simpower with global support and customization. It ensures timely help and solutions for unique project needs.
By following these, you’ll select a breaker that safeguards systems and enables smart control.
