EBS1B DPN Miniature 1P+N Circuit Breaker

EBS1B DPN Miniature Circuit Breaker (MCB)
1. Product Identity & Core Design
The EBS1B DPN (also called "Phase+Neutral" circuit breaker or MCB DZ30 DPN) features an elegant appearance and innovative structure, engineered specifically for residential electrical applications. It aligns with the IEC60898-1 international standard, ensuring compliance with global safety and performance benchmarks.

2. Key Electrical Specifications
Tailored for 230V AC 50/60Hz power systems, it adopts a 1P+N pole configuration with selectable rated currents from 3A to 32A. Offering B/C tripping characteristics, it provides precise overload and short-circuit protection for diverse residential loads. A 4.5kA breaking capacity enables rapid fault current interruption to prevent equipment damage and safety hazards.

3. Durability & Installation Efficiency
It delivers exceptional longevity with 20,000 mechanical life cycles and 10,000 electrical life cycles, supporting long-term reliable operation. The breaker is designed for 35mm DIN-rail mounting, enabling quick, tool-free installation into standard residential distribution boards and simplifying system maintenance or expansion.

4. Environmental Adaptability
It operates stably in ambient temperatures from -5°C to +40°C (24h average ≤+35°C), at altitudes up to 2,000m, and under relative humidity ≤95%. Rated for **Pollution Level II**, it performs reliably in typical residential environments, requiring installation on surfaces free of obvious vibration or impact.
