IMO UB10C2032A 32 Amp 2 Pole Miniature Circuit Breaker: UL 489, C Curve, 10kA
DIN rail mount 32 amp miniature circuit breaker for industrial branch circuit protection. Features two-pole switching, C-curve tripping, thermo-magnetic operation and a 10kA short circuit breaking capacity.
✅ Designed for Industrial Branch Circuit Protection
The IMO Precision Controls UB10C2032A protects electrical circuits against overload and short circuit conditions. Its 32 amp rating and two-pole configuration support applications that require coordinated protection and disconnection across two conductors.
The breaker’s C tripping curve accommodates the moderate startup current produced by equipment such as transformers, relays, contactors and small motors while maintaining dependable protection during sustained overloads and electrical faults.
Reliable 32 Amp Protection for Industrial Control Panels
The IMO UB10C2032A 32 amp miniature circuit breaker provides thermo-magnetic overcurrent protection for industrial control panels, machine automation systems and electrical distribution equipment. Thermal tripping responds to sustained overload conditions, while magnetic tripping quickly isolates high-current short circuits to help reduce damage to wiring and connected equipment.
UL 489 approval allows the UB10C2032A to be used for qualifying branch circuit protection applications. Its compact DIN rail housing supports efficient panel layouts, while the built-in contact position indicator gives technicians a clear way to verify breaker status during operation, inspection and troubleshooting.

⚠️ Installation Requirements
Qualified installation: Installation and servicing should be completed by qualified electrical personnel in accordance with applicable electrical codes.
Verify circuit requirements: Confirm that the breaker’s current, voltage, pole configuration and interrupting capacity are appropriate for the application.
Terminal torque: Tighten connected conductors to the specified 2.5 Nm (22.2 lb-in) fastening torque.
🔧 Thermo-Magnetic Protection
Thermal protection: Responds to sustained overload current that can overheat conductors or damage connected equipment.
Magnetic protection: Trips rapidly when a high short circuit current is detected, helping isolate the fault before damage spreads.
C-curve response: Allows moderate equipment startup current while maintaining dependable circuit protection.
🏭 Common Applications
The IMO UB10C2032A is well suited for branch circuits inside industrial control panels and OEM machinery that require a two-pole, 32 amp circuit breaker. Its C-curve response helps prevent nuisance tripping when connected equipment produces a moderate startup current.
It can also protect circuits associated with machine automation systems, electrical distribution equipment and panel-mounted control assemblies when the application falls within the breaker’s specified voltage, temperature and fault-current ratings.
