Reliable Protection for Industrial Control Circuits
The IMO US10C2040A automatically disconnects an electrical circuit when excessive current is detected. Its thermal element responds to sustained overload conditions, while its magnetic mechanism rapidly interrupts higher-current short circuits. This dual-action design helps reduce the risk of damage to cabling, machinery and electrical control components.
As a UL1077 supplementary protector, the US10C2040A is intended for installation within electrical equipment where suitable branch-circuit protection is already provided. Its compact modular construction makes it particularly well suited to industrial control panels and machinery enclosures where panel space is limited.
