Product Introduction
The Allen-Bradley 815-BOV169 Manual Reset Overload Relay is a dependable motor protection device designed to safeguard industrial equipment from overload conditions. Developed by Rockwell Automation under the trusted Allen-Bradley lineup, this relay is widely used in motor control circuits requiring reliable thermal protection and manual reset functionality.
This overload relay is engineered to monitor motor current and react to prolonged overcurrent conditions that could otherwise lead to motor damage or system failure. Once an overload condition is detected, the relay trips and interrupts the circuit, requiring a manual reset before the system can resume operation. This feature enhances operational safety by ensuring that faults are addressed before restarting.
Its compact construction and robust internal design make it suitable for installation in control panels, motor starters, and industrial distribution systems. The device is optimized for consistent performance in 600 VAC environments, offering stable and reliable protection across a wide range of industrial applications.

FAQ
- How does the overload relay detect an overload condition?
The relay uses a thermal sensing mechanism that responds to current flow over time. When the current exceeds a predefined level for a sustained period, the internal element heats up and triggers a trip. - What happens after the relay trips?
Once tripped, the relay opens the control circuit, stopping the motor. It remains in this state until it is manually reset by an operator. - Why is manual reset important in industrial applications?
Manual reset ensures that the cause of the overload is investigated before restarting, reducing the risk of repeated faults and equipment damage. - Can this relay be used with different types of motors?
Yes, it is suitable for various AC motor types, provided the operating conditions match the relay’s specifications. - Is the relay affected by ambient temperature changes?
While thermal relays are influenced by temperature, they are designed to operate within specified ranges to maintain reliable protection performance. - How is the relay installed in a control system?
It is typically mounted within a motor starter assembly or control panel and connected in series with the motor control circuit. - Does the relay provide short-circuit protection?
No, overload relays are designed for overload protection only. Short-circuit protection must be provided by additional devices such as circuit breakers or fuses. - Can the trip setting be adjusted?
Depending on the model configuration, some overload relays allow adjustment of the current setting to match the motor’s rated current. - What is the typical response time of the relay?
The response time depends on the magnitude of the overload. Higher overload currents will result in faster trip times. - Is this relay suitable for continuous operation?
Yes, it is designed for continuous monitoring of motor current and can operate reliably over extended periods in industrial environments.
