Description
About the Product
Exora Combo MCB 32A DP AC + 32A DP DC 10kA C Curve is a high-capacity dual-protection device that integrates both AC and DC miniature circuit breakers into a single compact unit. It is designed for advanced hybrid electrical systems where both AC distribution and DC power sources operate together, such as solar PV and battery storage installations.
How the Mechanism Works
The combo unit contains two independent thermal magnetic breakers:
- The AC MCB (240V AC, 32A) protects AC circuits against overload and short circuit faults.
- The DC MCB (500V DC, 32A) protects DC circuits such as solar arrays and battery systems.
Both breakers operate using:
- Thermal tripping for overload protection
- Magnetic tripping for instantaneous short circuit interruption
The C curve tripping characteristic enables moderate inrush current handling, ensuring smooth operation without nuisance tripping.
Electrical Configuration
- AC Side:
o Current: 32A
o Voltage: 240V AC
o Poles: Double Pole (DP)
- DC Side:
o Current: 32A
o Voltage: 500V DC
o Poles: Double Pole (DP)
- Breaking Capacity: 10kA (both AC and DC sides)
The DP configuration ensures simultaneous disconnection of both conductors, providing complete isolation for both AC and DC circuits.
Safety & Protection
This combo MCB provides:
- Protection against overload conditions
- Protection against short circuit faults
- Full isolation for both AC and DC systems
- Safe operation during maintenance and emergency conditions
Its 10kA breaking capacity ensures safe interruption of higher fault currents in demanding hybrid installations.
Mounting and Durability
Designed for DIN rail mounting, the combo MCB helps reduce panel space by combining two breakers into a single unit. Its compact and robust construction ensures reliable performance, durability, and long service life in industrial and renewable energy environments.
Application Domains
Ideal for advanced hybrid electrical systems such as:
- Solar photovoltaic (PV) installations
- Hybrid inverter systems
- Battery energy storage systems (BESS)
- Residential and commercial solar systems
- Industrial panels with combined AC and DC circuits
Key Features
- Dual protection: AC + DC in one unit
- AC rating: 32A, 240V AC
- DC rating: 32A, 500V DC
- Double pole (DP) configuration for both circuits
- Breaking capacity: 10kA
- C curve tripping characteristic
- Thermal magnetic protection mechanism
- Complete isolation of AC and DC circuits
- Space-saving compact design
- DIN rail mounting compatible
- Suitable for high-load hybrid systems
Applications
- Solar PV hybrid systems
- Battery storage systems
- Residential and commercial installations
- Industrial automation panels
- Mixed AC and DC distribution systems
