Reliable Protection for Industrial Electrical Systems
Miniature circuit breakers automatically disconnect an electrical circuit when excessive current is detected. Thermal protection responds to sustained overload conditions, while magnetic protection operates rapidly during short circuits. This helps protect cables, machinery and connected electrical equipment from damage.
The D curve characteristic of the IMO UB10D3010A allows higher temporary inrush currents before magnetic tripping occurs. This makes the breaker well suited to industrial loads that draw a substantial starting current while still providing dependable protection during genuine electrical faults.
Typical Applications
- Three-phase motor circuits.
- Industrial control panels.
- Transformers and inductive loads.
- Machine building and OEM equipment.
- Factory automation systems.
- Commercial and industrial distribution boards.
