Electronic Shear Pin

Industrial wastewater treatment system with Load Controls PMP-25 for pump monitoring and process optimization.

In heavily geared or high-torque drive systems, a mechanical jam can transmit enormous force through the drivetrain before a conventional overload relay responds. The result is broken shafts, damaged gearboxes, and costly repairs that take equipment offline for extended periods.

Load Controls' power sensors provide an electronic shear pin function, acting as a virtual mechanical fuse for motor-driven equipment without the replacement cost or downtime of a physical shear pin. When load spikes beyond a configured threshold, indicating a jam or sudden overload, the sensor triggers an instant motor shutdown, protecting the drivetrain, gearbox, and connected equipment. Response times are adjustable to match the mechanical characteristics of your specific drive system. All sensors are non-invasive, install at the motor control panel, and are manufactured in the USA to ISO 9001:2015 standards.

Q: What is the advantage of an electronic shear pin over a mechanical one?

A mechanical shear pin requires physical replacement after every trip, taking equipment offline and requiring maintenance intervention. An electronic shear pin resets without physical replacement, restoring operation far more quickly.


Q: Can the electronic shear pin function be combined with other monitoring functions?

Yes. Load Controls sensors can simultaneously provide electronic shear pin protection, overload detection, and loss-of-load monitoring from a single unit.
