Description
About the Product
Exora MCB 4A DP 500V DC 10kA C Curve is a double pole miniature circuit breaker designed for low-current, high-voltage DC applications. It provides reliable protection against overload and short circuit faults while ensuring complete isolation of both conductors in DC electrical systems.
How the Mechanism Works
The breaker operates using a thermal magnetic protection mechanism:
- The thermal element responds to sustained overload conditions with a time-delayed response, protecting cables and connected equipment from overheating.
- The magnetic element ensures instantaneous tripping during short circuit faults, enabling rapid and safe disconnection.
The C curve tripping characteristic allows moderate inrush current handling, ensuring stable performance without nuisance tripping.
Electrical Configuration
This is a double pole (DP) MCB rated at:
- Current: 4A
- 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 installations.
Safety & Protection
The breaker provides protection against:
- Overload conditions
- Short circuit faults
Its 10kA high breaking capacity allows safe interruption of high fault currents. The double pole design ensures full circuit isolation, which is critical for safety in high-voltage DC environments.
Mounting and Durability
Designed for DIN rail mounting, the breaker allows easy installation in DC distribution panels and control boards. Its compact and rugged construction ensures long-term durability and reliable performance in demanding conditions.
Application Domains
Suitable for advanced DC systems including:
- Solar photovoltaic (PV) systems (high-voltage strings)
- Battery energy storage systems (BESS)
- DC distribution panels
- Industrial automation systems
- Telecom and instrumentation circuits
Key Features
- Rated current: 4A
- 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 systems
- Battery storage systems
- DC control panels
- Industrial automation systems
- Telecom installations
