IP55 Rated 1P/2P/3P/4P DIN Rail Circuit Breaker with Overload and Short Circuit Protection

The EDB1-63 series miniature circuit breakers are designed for reliable circuit protection in various electrical applications. These DIN rail mounted devices offer comprehensive protection against overloads and short circuits in DC systems up to 1000V.

With rated currents ranging from 6A to 63A, these breakers are suitable for multiple applications including photovoltaic systems, communication equipment, and commercial lighting distribution. The units feature energy limitation class 3 protection and are available in 1P, 2P, 3P, and 4P configurations.

The breakers comply with IEC/EN 60898-1 standards and offer excellent mechanical durability with 20,000 operation cycles. Their compact design allows for space-efficient installation on standard DIN rails, making them ideal for panel builders and electrical contractors.

Key protection features include conventional circuit breaker functionality, circuit-breaker failure protection, overcurrent protection, and overvoltage protection (OVP). The units are available with both Type B (3-5x In) and Type C (5-10x In) tripping characteristics to suit different application requirements.

These circuit breakers are certified to ISO9001-2000, CE, CB, CCC, and SAA standards, ensuring compliance with international safety requirements. The robust construction includes arc-extinguishing in air and reliable terminal connections for conductors up to 25mm².
