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.
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.

The IMO US10D3063A is used to protect three-phase industrial circuits and connected equipment against overload and short-circuit conditions.
The breaker has a rated current of 63 A, making it suitable for higher-load industrial electrical circuits.
A D curve breaker permits relatively high temporary starting currents before its instantaneous magnetic trip operates, making it suitable for motors, transformers and other inductive loads.
The US10D3063A has a three-pole configuration designed for coordinated protection and isolation of three-phase circuits.
The breaker is designed for mounting on a standard 35 mm DIN rail inside a suitable electrical panel or protective enclosure.
