## Summary description

The LOVATO Electric SM2X14400 is an undervoltage release designed for side mounting on SM2R and SM3R series motor protection circuit breakers. It operates at 400V AC with a frequency of 50/60Hz. This accessory ensures reliable protection by automatically tripping the circuit breaker when the supply voltage drops below a specified threshold, enhancing safety in industrial electrical systems.

## Long description

The LOVATO Electric SM2X14400 is a specialized undervoltage release accessory engineered for seamless integration with SM2R and SM3R series motor protection circuit breakers. Designed for side mounting, this component serves as a critical safety mechanism in industrial electrical installations by monitoring the supply voltage and triggering an automatic trip of the circuit breaker if the voltage falls below the required operational threshold.
Advantages
This undervoltage release provides a robust solution for protecting sensitive electrical equipment from the risks associated with low voltage conditions. By ensuring that the circuit breaker disconnects power when voltage levels become unstable, it prevents potential damage to motors and connected machinery. The side-mounting design allows for efficient installation without occupying additional space on the DIN rail, maintaining a compact footprint within the control panel while ensuring reliable and consistent performance in demanding industrial environments.
Suitable for
Industrial motor control centers
Protection of machinery against voltage drops
Automated electrical safety systems
Integration with SM2R and SM3R circuit breakers
When it may not be suitable
This device is specifically calibrated for use with the LOVATO Electric SM2R and SM3R series and is not compatible with other circuit breaker models. It is intended for AC systems operating at 400V and should not be used in DC applications or systems with different voltage requirements.
Key specifications
Rated voltage: 400V AC
Frequency: 50/60Hz
Mounting type: Side mount
Compatibility: SM2R and SM3R series motor protection circuit breakers
How to use
Installation should be performed by a qualified electrician in accordance with local safety regulations. Ensure the main power supply is disconnected before attempting to mount the accessory. The unit is designed to be attached to the side of the compatible circuit breaker. Once physically secured, connect the control wiring according to the provided technical diagrams to ensure the release can monitor the supply voltage effectively. After installation, perform a functional test to verify that the circuit breaker trips correctly when the voltage is removed or drops below the threshold.
What to consider before purchase
Verify the voltage rating of your electrical system matches the 400V AC requirement.
Confirm that your existing circuit breaker is part of the SM2R or SM3R series.
Ensure there is sufficient physical space on the side of the circuit breaker for mounting.
Usage recommendations
Always verify that the control circuit voltage matches the rated voltage of the release to prevent malfunction or damage to the device. Regular inspection of the connection points is recommended to ensure long-term operational reliability.
