BRCB-15/30/40 TP Type 2 Surge Protection Device with Mini Circuit Breaker
In today’s increasingly electrified world, protecting electrical systems from power surges has become more critical than ever. The BRCB-15/30/40 TP Type 2 Surge Protection Device (SPD) combined with a Mini Circuit Breaker offers a comprehensive solution for safeguarding electrical installations against transient overvoltages. This innovative device combines the best of both worlds – superior surge protection and reliable circuit breaking functionality.
Understanding Type 2 Surge Protection
Type 2 surge protection devices are designed to protect electrical installations from indirect lightning strikes and switching transients. The BRCB series represents a significant advancement in this technology by integrating a miniature circuit breaker directly into the SPD unit. This combination provides several distinct advantages over traditional standalone surge protectors.
The Type 2 classification indicates that these devices are intended for installation at the distribution board level, typically as secondary protection following a Type 1 SPD at the service entrance. The BRCB-15/30/40 TP models offer varying levels of protection to suit different installation requirements and risk levels.
Key Features of BRCB Series
The BRCB series stands out with several notable features:
- Integrated Protection: Combines surge protection and overcurrent protection in a single compact unit
- Visual Status Indication: Clear indication of protection status and end-of-life warning
- Thermal Disconnect: Automatic disconnection when the device overheats or reaches end-of-life
- Compact Design: Space-saving solution that fits standard distribution boards
- Easy Maintenance: Modular design allows for quick replacement when needed
Technical Specifications
The BRCB series comes in three main variants:
| Model | Maximum Discharge Current (Imax) | Nominal Discharge Current (In) | Voltage Protection Level (Up) |
|---|---|---|---|
| BRCB-15 TP | 15 kA | 7.5 kA | ≤ 1.5 kV |
| BRCB-30 TP | 30 kA | 15 kA | ≤ 1.5 kV |
| BRCB-40 TP | 40 kA | 20 kA | ≤ 1.5 kV |
Installation Considerations
Proper installation is crucial for optimal performance of the BRCB series SPDs. These devices should be installed:
- At the origin of the electrical installation or sub-distribution boards
- In parallel with the electrical system being protected
- With proper earthing connections
- Following all local electrical codes and regulations
The integrated miniature circuit breaker provides several benefits during installation and operation. It serves as both an overcurrent protection device and a means of dis
