Schneider Electric Vamp 125 vs Blue Jay AFR-4 Arc Flash Relays

Vamp 125 vs AFR-4

When selecting arc protection relays, Schneider Electric Vamp 125 and Blue Jay AFR-4 cater to distinct needs. The Vamp 125 excels in high-security environments like industrial power systems and utilities, offering ultra-fast response times (≤2ms for light+current, 1ms for light-only) and advanced features such as dual protection zones, fault waveform recording, and multi-protocol support (Modbus RTU, IEC 61850, DNP3). Ideal for medium/low-voltage switchgear, it integrates seamlessly with larger protection systems like VAMP 221/321, ensuring reliability for critical infrastructure

In contrast, Blue Jay AFR-4 prioritizes affordability and practicality for low-voltage/small MV systems. With ≤15ms response (light+current) and ≤5ms (light-only), it provides essential arc detection and overcurrent coordination. Its MT mode supports busbar zoning logic, while six relay outputs and Modbus RTU communication ensure flexibility for cost-sensitive projects like building power distribution or feeder cabinets. The AFR-4’s budget-friendly design and functional versatility make it a strong contender for SMEs and OEMs seeking reliable protection without premium costs.

Both devices enhance safety and minimize downtime—choose Vamp 125 for mission-critical systems or AFR-4 for economical, scalable solutions. Upgrade your protection strategy today with precision-engineered reliability!
