Why Choose the IMO US10D3063A Miniature Circuit Breaker?
The IMO US10D3063A is a robust three-pole miniature circuit breaker and supplementary protector designed to provide dependable overcurrent protection within industrial control panels, machinery and automation systems. Part of the IMO US10 circuit protection range, it offers a compact and practical solution for protecting three-phase electrical circuits against overload and short-circuit conditions.
With a rated current of 63 A and a D curve tripping characteristic, the US10D3063A is particularly suitable for equipment that produces high inrush currents during start-up. This makes it an effective choice for motors, transformers, solenoids and other inductive industrial loads where a more tolerant instantaneous trip response is required.
The breaker features a space-efficient modular construction for installation on a standard 35 mm DIN rail. Its three mechanically linked poles provide simultaneous circuit isolation across three-phase systems, helping panel builders and machine manufacturers achieve reliable protection, convenient installation and straightforward maintenance.
Key Advantages
- Compact three-pole circuit protection device for industrial applications.
- 63 A rated current for higher-load electrical circuits.
- D curve tripping characteristic suitable for equipment with high starting currents.
- Provides protection against overload and short-circuit faults.
- Mechanically linked poles support coordinated isolation of three-phase circuits.
- DIN rail mounting enables quick installation inside control cabinets.
Key Features

Reliable Protection for High-Inrush Industrial Loads
The IMO US10D3063A uses thermal-magnetic operation to protect connected equipment from damaging electrical faults. The thermal element responds to sustained overload conditions, while the magnetic mechanism provides rapid disconnection when a significant short-circuit current is detected.
Its D curve characteristic permits a higher temporary inrush current than breakers with B or C curve characteristics. This helps reduce unnecessary tripping when motors, transformers and similar inductive equipment are energised, while maintaining reliable protection against genuine fault conditions.
Typical Applications
- Industrial control panels and switchgear assemblies.
- Three-phase motor and machinery circuits.
- Transformers and inductive electrical loads.
- Manufacturing and production equipment.
- OEM automation systems.
- Pumps, compressors and material handling machinery.
