Product Selection 1
Feature Description
Carrying Endurance
Meets the withstand requirements of the following currents:
• The rated current value is calculated according to the rated power of the load, and the
current value of other electrical appliances needs to be considered
• Calculate the peak current according to the peak power of the load and the overload time is
confirmed
Recommended applications - contact make
• Capacitive/active load:Pre-charger、Motor Controller、Charger、Compressor、DC/DC、
Power steering etc.
• Resistive load:PTC、Heating film
Recommended applications - contact break
• Main Relay:Small current/rated current/peak current /10 times short-circuit current cut-off
capacity
• Charge Relay:Charging current/10 times short-circuit current cut-off capacity
• Auxiliary Relay:Rated current/peak current/10 times short-circuit current cut-off capacity
• Pre-charge Relay:Non cut-off capacity needed (still can stand 10 times cut-off)
Short Circuit Current
Main relay and normal charge rely : No fire or explosion after short circuit.
