Description
About the Product
Exora MCB 10A SP 250V DC 10kA C Curve is a single pole miniature circuit breaker designed for medium-load DC applications requiring enhanced fault interruption capability. It ensures reliable protection against overload and short circuit conditions in demanding DC systems.
How the Mechanism Works
The breaker operates using a thermal magnetic protection mechanism:
- The thermal element responds to sustained overload conditions, providing delayed tripping to protect cables and connected equipment.
- The magnetic element ensures instantaneous tripping during short circuit faults, enabling fast and effective fault isolation.
The C curve tripping characteristic supports moderate inrush current, preventing nuisance tripping while maintaining system stability.
Electrical Configuration
This is a single pole (SP) MCB rated at:
- Current: 10A
- Voltage: 250V DC
- Breaking capacity: 10kA
The 10kA high breaking capacity allows safe interruption of higher fault currents, making it suitable for installations with higher fault levels compared to standard 6kA breakers.
Safety & Protection
The breaker provides protection against:
- Overload conditions
- Short circuit faults
Its enhanced 10kA fault interruption capability significantly improves safety, ensuring protection of cables, connected equipment, and electrical systems.
Mounting and Durability
Designed for DIN rail mounting, the breaker allows easy installation in DC panels and distribution boards. Its compact and durable design ensures long service life and reliable performance in industrial and commercial environments.
Application Domains
Suitable for a wide range of DC applications including:
- Solar photovoltaic (PV) systems
- Battery energy storage systems (BESS)
- DC distribution systems
- Industrial automation and control panels
- Telecom and instrumentation circuits
Key Features
- Rated current: 10A
- Single pole (SP) configuration
- Rated voltage: 250V DC
- Breaking capacity: 10kA
- C curve tripping characteristic
- Thermal magnetic protection mechanism
- High fault interruption capability
- DIN rail mounting compatible
- Suitable for DC applications
- Compact and durable construction
Applications
- Solar PV systems
- Battery storage systems
- DC control panels
- Industrial automation systems
- Telecom installations
