# BRCB-15/30/40 TP Type 2 Surge Protection Device with Mini Circuit Breaker
## Introduction to Surge Protection Devices
Surge protection devices (SPDs) play a crucial role in safeguarding electrical systems from voltage spikes and transient overvoltages. The BRCB-15/30/40 TP Type 2 SPD with integrated mini circuit breaker represents an advanced solution for residential and commercial applications.
## Key Features of BRCB-15/30/40 TP
The BRCB series offers several important features:
– Type 2 protection according to IEC 61643-11
– Integrated thermal disconnector
– Built-in mini circuit breaker for overload protection
– Visual status indicators
– Compact DIN rail mounting design
## Technical Specifications
Parameter | Value
Maximum continuous operating voltage (Uc) | 275V AC
Nominal discharge current (In) | 15kA, 30kA, or 40kA
Voltage protection level (Up) | ≤1.5kV
Response time | <25ns
Operating temperature range | -40°C to +80°C
## Installation and Applications
The BRCB-15/30/40 TP is designed for easy installation in distribution boards:
The device should be installed in parallel with the electrical system, preferably as close as possible to the point of entry of the power supply. The integrated mini circuit breaker provides both protection and a convenient means of disconnection for maintenance purposes.
Common applications include:
– Residential electrical panels
– Small commercial buildings
– Industrial control panels
– Telecommunication equipment protection
## Advantages Over Conventional SPDs
The combination of surge protection with a mini circuit breaker offers several benefits:
– Space-saving design reduces panel footprint
– Simplified wiring with integrated disconnection
– Enhanced safety with dual protection
– Easy replacement without complex rewiring
– Clear visual indication of protection status
## Maintenance and Replacement
Regular inspection of the status indicators is recommended. When the SPD reaches its end of life (indicated by the status window), the entire unit can be easily replaced by disconnecting the mini circuit breaker and sliding the device off the DIN rail.
The BRCB-15/30/40 TP provides reliable protection with minimal maintenance requirements, making it an excellent choice for modern electrical installations.
