BMT 40A DIN Rail Adjustable Over/Under Voltage Protection Relay AC 220V

The BMT 40A DIN Rail Over/Under Voltage Protector is a versatile and reliable device designed to safeguard electrical equipment from harmful voltage fluctuations. Suitable for both industrial and residential applications, this adjustable relay monitors AC supply voltage and automatically disconnects the load when the voltage exceeds or falls below predefined thresholds.

With a rated current range from 1A to 80A (default 40A), this protector ensures flexible deployment for a variety of load capacities. The over-voltage cut-off is adjustable from 240V to 300V (default 270V for 220V systems), while the under-voltage cut-off is adjustable from 140V to 210V (default 170V for 220V systems). Users can also configure overcurrent settings between 1A and 63A as needed.

Key features include a boot delay time adjustable from 1s to 300s (default 5s), low power consumption 2W, and a robust mechanical life of 100,000 operations. The protector is designed for operation in environments with temperatures ranging from -5 C to +40 C and is compatible with both 220VAC 50Hz and 120VAC 50Hz systems.

The BMT DIN Rail protector is ideal for industrial automation, home appliances, and sensitive electronic systems, offering reliable protection against over-voltage, under-voltage, and overcurrent conditions while maintaining system stability and extending the lifespan of connected devices.
