Description
About the Product
Exora MCB 6A DP 500V DC 10kA C Curve is a double pole miniature circuit breaker designed for low to medium current, high-voltage DC applications. It provides reliable protection against overload and short circuit faults while ensuring complete isolation of both conductors in DC systems.
How the Mechanism Works
The breaker operates using a thermal magnetic protection mechanism:
- The thermal element responds to sustained overload conditions with time-delayed tripping, protecting cables and connected equipment from overheating.
- The magnetic element ensures instantaneous tripping during short circuit faults, enabling rapid disconnection and minimizing potential damage.
The C curve tripping characteristic allows moderate inrush current handling, ensuring stable operation without nuisance tripping.
Electrical Configuration
This is a double pole (DP) MCB rated at:
- Current: 6A
- Voltage: 500V DC
- Breaking capacity: 10kA
The DP configuration ensures simultaneous disconnection of both conductors (positive and negative), while the 500V DC rating makes it suitable for high-voltage DC systems such as solar arrays and battery banks.
Safety & Protection
The breaker provides protection against:
- Overload conditions
- Short circuit faults
Its 10kA high breaking capacity enables safe interruption of high fault currents, while the double pole design ensures full circuit isolation, which is essential in high-voltage DC environments for safety and maintenance.
Mounting and Durability
Designed for DIN rail mounting, the breaker allows easy installation in DC distribution boards and control panels. Its compact and rugged construction ensures long-term durability and consistent performance in demanding industrial and renewable energy applications.
Application Domains
Suitable for advanced DC systems including:
- Solar photovoltaic (PV) systems (high-voltage DC strings)
- Battery energy storage systems (BESS)
- DC distribution panels
- Industrial automation systems
- Telecom and instrumentation circuits
Key Features
- Rated current: 6A
- Double pole (DP) configuration
- Rated voltage: 500V DC
- Breaking capacity: 10kA
- C curve tripping characteristic
- Thermal magnetic protection mechanism
- Complete isolation of both conductors
- High fault interruption capability
- DIN rail mounting compatible
- Suitable for high-voltage DC applications
- Compact and durable design
Applications
- Solar PV high-voltage DC systems
- Battery storage systems
- DC control and distribution panels
- Industrial automation systems
- Telecom infrastructure
