XCMG Power Relay 803600882
XCMG 803600882 is listed as a power-relay assembly associated with MZJ-400A006 and MZJ-50A references. It switches higher-current DC circuits under a control command; coil voltage and terminal function are critical.
Identification and Matching
XCMG number 803600882
MZJ-400A006 and MZJ-50A labels
Coil voltage and polarity
Main and auxiliary terminal layout
Mounting and controlled load
Application and Service Scenarios
Replace after verified burned or welded contacts, open coil, heat damage or excessive voltage drop. Batteries, wiring, fuses, control relays and the load can produce similar symptoms.
Inspection and Installation
Isolate battery power, label heavy cables and use correct terminal torque and insulation. Test coil command, voltage drop and heating under the specified load.
Frequently Asked Questions
Does a click prove the relay is good?
No. Main contacts may remain high resistance.
Can coil voltage be assumed?
No. Read the original label and circuit data.
Can terminals be bridged?
Bypassing creates serious electrical and fire risk.
Export Packing
Terminals are insulated and the relay is cushioned against shock and shorting.
