Cole Hersee Continuous Duty Solenoid Switch 12V 100A Normally Open 24512-10BX

The Cole Hersee Continuous Duty Solenoid Switch 24512-10BX is a 12V, 100A unit with a normally open SPST Off/On action. It is described as a continuous duty solenoid, making the duty rating and switching style the key details to check when matching it to a vehicle or equipment application.

Mounting details are also clearly defined, with mounting holes sized 8mm x 15mm and 56mm centre-to-centre. Plated steel nuts and washers are included, which helps when you are replacing an existing solenoid and want the mounting hardware to suit the supplied unit.

Application and Buying Notes

For replacement work, the main compatibility checkpoints are the part number 24512-10BX, the 12V system voltage, and the 100A continuous duty rating. If the original unit is a normally open solenoid with an SPST Off/On function, that is another strong match point before ordering.

Terminal style matters just as much as the electrical rating. This unit has 2 blade and 2 stud terminals, 5/16 - 24 copper stud threads, and an insulated 10-32 copper coil terminal. If the existing installation uses a different terminal style or thread size, the physical connection may not line up even if the voltage is correct.

Mounting should also be checked carefully. The listed mounting holes are 8mm x 15mm with 56mm centre-to-centre spacing, so confirm that the bracket, tray, or firewall mounting points in the vehicle or equipment can accept those dimensions. The included plated steel nuts and washers are useful, but they do not replace the need to confirm the mounting pattern first.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number 24512-10BX helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Continuous Duty Solenoid 12V 100A Normally Open. Part number 24512-10BX should be checked first. Listed voltage is 12. Listed output rating is 100. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 24512-10BX, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a solenoid switch in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 100 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by matching the part number 24512-10BX, the 12V 100A continuous duty rating, the normally open SPST action, and the terminal and mounting dimensions before purchase.
