# Lightning Protection Device BRCB-15/30/40 Type 2 with Integrated Mini Circuit Breaker
## Introduction to Surge Protection
In today’s increasingly electrified world, protecting electrical systems from power surges has become essential. The BRCB-15/30/40 Type 2 Surge Protection Device (SPD) with integrated Mini Circuit Breaker represents a significant advancement in electrical protection technology. This innovative device combines surge protection with circuit breaking capabilities in a single compact unit.
## Key Features of BRCB-15/30/40 Type 2 SPD
1. Comprehensive Protection
The BRCB series offers Type 2 surge protection, designed to protect against indirect lightning strikes and switching transients. The integrated Mini Circuit Breaker provides additional protection against overloads and short circuits.
2. Multiple Current Ratings
Available in three variants (15A, 30A, and 40A), the BRCB series can accommodate different electrical load requirements while maintaining optimal protection levels.
3. Space-Saving Design
The combination of SPD and circuit breaker in one device saves valuable panel space while simplifying installation and maintenance procedures.
