1-Pole MCB with C-Curve for Overload and Short Circuit Protection in DC Circuits
The DC 500 V Mini Circuit Breaker is a compact protective device designed for direct current (DC) electrical circuits with voltages up to 500 V DC — commonly used in solar photovoltaic (PV) systems, battery installations and DC distribution boards. It acts as an automatic circuit breaker and isolator, protecting circuits from overload and short‑circuit faults.
Key Features:
Rated Voltage: up to 500 V DC, suitable for PV solar applications and other DC systems.
Pole: 1‑pole (1P) — breaks the positive line in DC circuits.
Overload Protection: trips automatically if current exceeds the set rating.
Short‑Circuit Protection: magnetic/thermal trip to interrupt dangerous fault currents.
Current Rating Options: available in 6 A, 10 A, 16 A, 20 A, 25 A, 32 A, 40 A, 50 A, 63 A, etc.
Mounting: standard 35 mm DIN rail for easy installation in panels and distribution boxes.
Compact Design: space‑saving footprint suitable for tight installations.
Safety: compliant with IEC/EN standards with thermal‑magnetic trip characteristics.
Function:
In normal operation, the breaker allows current to flow. When the current load becomes excessive — due to overload or a short‑circuit — the internal thermal or magnetic mechanism automatically trips the circuit, preventing wire damage, equipment failure, or fire hazards in DC systems.
Typical Applications:
Solar PV arrays (string protection between panels and inverters/charge controllers)
DC distribution boards
Battery banks and energy storage systems
DC power systems in off‑grid and backup scenarios
Industrial DC installations and protection points
Benefits:
Reliable protection for high‑voltage DC circuits
Safe isolation for maintenance
Compact DIN rail‑mounted design
Multiple current rating options to match specific system needs
