Battery Switch Relay JK451A
A 12V or 24V 100A battery switch relay assembly that cross references OEM part numbers JK451 and 1417036600001, fitted to STEYR, FOTON, AUMAN trucks, excavators, engineering vehicles and buses. It controls the main battery circuit by connecting or disconnecting the positive terminal under manual or automatic command. Supplied in neutral, customised or CHINO branded packaging with a 12 month warranty from B/L date.
MOQ 10 pcs · Free samples, freight at your cost · Neutral or own brand packing · 12 month warranty from B/L date
Key Benefits
- Cross references two OEM part numbers so one line item covers multiple vehicle builds
- 100A capacity handles high current draw from starter motors and auxiliary systems
- Dual voltage compatibility (12V and 24V) supports both light and heavy commercial vehicles
- Mechanical power switch design allows manual override in case of electrical failure
- Plugs directly into the original loom with no rewiring required at the workshop
- Twelve month warranty from B/L date protects distributor and fleet inventory
Application Scenarios
Where It Is Used
- Fleet workshops replacing failed battery switches on STEYR and AUMAN trucks after prolonged electrical load
- Aftermarket distributors stocking battery relays for engineering machinery and excavators
- Truck repair chains diagnosing vehicles that fail to start due to open battery circuits
- Body builders integrating battery switches into new chassis for FOTON and AUMAN vehicles
Who It Is For
- Truck parts importers who buy against OEM numbers JK451 and 1417036600001

Use Guide
- Confirm the vehicle uses a 12V or 24V system before fitting
- Match the physical connector and mounting style against the original relay before ordering
- Disconnect the battery, remove the old relay, and install the replacement with correct orientation
- Test the switch by turning the ignition on and verifying the battery circuit closes fully
- If the switch fails to close, check the control signal wire and ground connection before replacing the relay
