HOMER UEM5-100 Technical data analysis
UEM5-100 is a plastic shell circuit breaker(including leakage protection function)produced by HOMER.It is suitable for low-voltage power distribution systems and has multi-level protection and intelligent design.The following are its core technical data:
1.Basic parameters
Rated current
Shell current:100A(supports breaking capacity classification:standard type,higher breaking type,high breaking type,current limiting type).
Rated operating current:6A to 100A(specific models may vary,such as 63A rated for UEM5-100L/63-3300).
Voltage specifications
Rated operating voltage:415V AC(50Hz).
Rated insulation voltage:800V.
Break-off capability
Short circuit breaking capability:
Standard type(L):35kA(such as UEM5-100L/63-3300).
Higher breaking type(M):Higher breaking ability(specific valuesrequire reference model).
2.Protection function
Core protection
Overload protection:achieved through a thermomagnetic tripper.
Short circuit protection:The electromagnetic tripper quickly cuts off the fault current.
Undervoltage protection:Protection can still be triggered when line voltage is as low as 50V.
Leakage protection(UEM5L series):
The remaining operation current is adjustable(such as 30mA,100mA,etc.).
The action time supports non-delay and delay adjustment.
Additional protection
Excitation tripper:Supports remote control opening and is compatible with AC220V/415V or DC24V/110V voltage.
Alarm contact:Real-time feedback of overload,short circuit or undervoltage fault status.
III.Structure and Design
Material and shell
Shell material:pressed by IDI thermoset composite material,with high insulation and mechanical strength.
Protection level:IP20(closed type),some models support IP65(such as versions with quick loading and unloading connectors).
Contact system
Electromagnetic repulsive current limit design:the contact repels quickly during fault current to avoid arc reignitment and improve breakage capability.
Dynamic balance optimization:Peak-peak dynamic balance≤0.0127mm to ensure operational stability.
Installation and Extension
Installation method:front/back of the board,plug-in wiring,support rail installation.
Accessories compatibility:Auxiliary contacts,undervoltage trippers,etc.can be installed without removing the cover.
