Why Choose the IMO UB10C1030A Miniature Circuit Breaker?

The IMO UB10C1030A is a compact and dependable UL 489 miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. Part of the IMO UB10 circuit breaker series, it is suitable for industrial machinery, control panels, automation equipment and branch circuit protection applications.

This circuit breaker has a 30 A rated current, a C curve trip characteristic and a 10 kA short-circuit breaking capacity. The C curve operating characteristic makes it suitable for circuits containing equipment with moderate starting currents, including motors, transformers, solenoids and industrial control devices.

The UB10C1030A uses thermal and magnetic tripping mechanisms to provide reliable protection during sustained overloads and high-current faults. Its compact single-pole format and standard DIN rail mounting arrangement allow straightforward installation within machinery panels, electrical distribution boards and industrial control enclosures.

Reliable Circuit Protection for Industrial Installations

Miniature circuit breakers disconnect electrical circuits when excessive current is detected. Thermal protection responds to sustained overload conditions, while the magnetic trip mechanism provides rapid disconnection during short circuits. This combined operation helps protect wiring, machinery and connected equipment from electrical damage.

The IMO UB10 series is designed for panel builders, machine manufacturers and electrical engineers requiring compact and reliable circuit protection. Its DIN rail format supports efficient panel assembly, while the C curve characteristic makes it suitable for many industrial loads that produce moderate current surges during start-up.

Typical Applications

  • Industrial machinery and control panels.
  • Motor control and starter circuits.
  • Transformers and power supplies.
  • Automation and PLC equipment.
  • Commercial electrical distribution boards.
  • OEM machinery and production systems.
