X-37886 ALLEN-BRADLEY Overload Relay

Review ALLEN-BRADLEY A-b L.h. Overload Relay

The Allen-Bradley X-37886 A-B Single-Phase L.H. Overload Relay is a versatile and reliable electrical component designed for protecting motors and other loads against overcurrent conditions. This overload relay from Rockwell Automation is part of the PowerFlex Lite family, known for its compact size, ease of installation, and cost-effectiveness.

The X-37886 is a single-phase, Class "F" overload relay, which means it is suitable for applications with a normal operating current up to 15 amperes and a maximum overload current up to 125 amperes. The L.H. (line-to-ground) designation indicates that the relay is intended for protecting against ground faults.

This overload relay features a thermal-magnetic element that provides both overload and short-circuit protection. The thermal element responds to the temperature rise caused by an overload condition, while the magnetic element trips the relay when a short circuit occurs. The relay also includes a delay feature, which allows the motor to reach its normal operating temperature before the relay resets, reducing unnecessary downtime.

The Allen-Bradley X-37886 comes with a clear, easy-to-read scale on the dial, which enables operators to quickly assess the load status. The dial is graduated in amperes and includes a red warning zone to indicate when the load is approaching an overload condition. Additionally, the relay includes a removable pilot lamp, which illuminates when the relay trips, making it easy to identify the status of the protected load.

The X-37886 is designed for easy installation and wiring, with conveniently located terminals that accept up to a #10 AWG wire. The relay is also compatible with various mounting configurations, including panel mounting and DIN rail mounting, making it adaptable to various applications.

The Allen-Bradley X-37886 A-B Single-Phase L.H. Overload Relay is a durable and robust component, built to withstand the demands of industrial environments. It is UL listed and CE marked, ensuring compliance with various safety standards. With its reliable protection, ease of use, and versatile design, this overload relay is an essential component for any electrical system that requires overcurrent protection.

The Allen-Bradley X-37886 A-B Load Relay is a protective device used to disconnect overloaded or faulty loads from the power source. This type of relay is widely used in industrial automation applications due to its reliable performance and advanced features.
