Family Overview
Selection And Application Context
The 1P+N Miniature Circuit Breaker (DPN) series provides critical protection for modern electrical systems, particularly in single-phase applications. These devices are designed to safeguard against both overloads and short circuits, ensuring the safety and integrity of connected equipment and wiring. By combining protection for both the live and neutral conductors within one compact module, DPN MCBs simplify installation and optimize space on DIN rails.
Manufactured to comply with IEC60898-1 standards, our DPN circuit breakers are rated for a voltage of 240V and operate effectively across a frequency range of 50Hz to 60Hz. They are available with various tripping curves—B, C, and D—to accommodate different load characteristics and fault current levels. Tripping curve B responds to (3-5) times the rated current (In), curve C to (5-10)xIn, and curve D to (10-20)xIn, providing flexibility for diverse operational requirements.
Designed for longevity and consistent performance, these circuit breakers offer an electrical life of 10,000 cycles and a mechanical life of 20,000 cycles. Their IP20 degree of protection ensures basic safety against solid objects. Installation is straightforward with standard DIN-rail mounting, making them a practical choice for efficient panel assembly. We also offer ODM and private label manufacturing support, providing tailored solutions for OEM panel assemblers and electrical wholesalers seeking reliable, compliant circuit protection devices.
