HOMER UEM5-100 is a high-performance plastic case leakage circuit breaker designed for low-voltage power distribution systems.It is suitable for residential,commercial and industrial environments,providing multiple protection functions and high reliability.The following is a comprehensive analysis of its core functions and technical parameters:
I.Product Overview
The UEM5-100 series circuit breakers use a thermosetting composite shell from IDI,USA,with high strength and insulation performance to ensure stable operation of the whole machine.Its design integrates the electromagnetic repulsion current limiting principle,modular accessory system and wide voltage compatibility,and is suitable for low-voltage power grids with AC 50Hz and rated current of 6A to 800A.
II.Core Functions
Multi-function protection
Leakage protection:adjustable residual operating current(30/100/300mA,etc.),non-delayed or delayed operating time optional,line voltage as low as 50V can still work reliably to prevent electric shock and electrical fire.
Overload and short-circuit protection:realized by thermal magnetic tripping device,fast breaking speed,small tripping force,and support two-step breaking system to improve breaking capacity.
Undervoltage protection:ensure that the equipment automatically cuts off the power supply when the voltage fluctuates to avoid damage.
Flexible scalability
Box accessory design:Modules such as shunt release and auxiliary contacts do not need to be installed without removing the cover,and support insulation box design to enhance safety.
Shunt release compatibility:The rated voltage range covers AC220V to AC415V to prevent damage caused by wiring errors.
High interchangeability
Models with different breaking capacities in the same series have the same appearance and dimensions,which is convenient for installation and maintenance,and reduces the pressure on spare parts inventory.
