IMO UB10C2006A 6A UL 489 Circuit Breaker, 2-pole, C Curve, 10kA, 480Y/277V AC, 96V DC
6A 2-pole miniature circuit breaker with C-curve thermo-magnetic protection, 10kA interrupting capacity, DIN-rail mounting, and UL 489 approval.
Why Choose the IMO UB10C2006A Circuit Breaker?
The IMO Precision Controls UB10C2006A is a 6A 2-pole miniature circuit breaker for two-pole auxiliary-power and control branches designed around a 6A protective rating. It is rated for 480Y/277V AC or 96V DC and provides UL 489 branch-circuit protection in industrial control panels, machinery, and distribution equipment when applied within its electrical ratings.
Thermo-magnetic operation combines a thermal response for sustained overloads with rapid magnetic tripping during severe faults. The C-curve characteristic is designed for correctly engineered loads with moderate inrush, while the contact-position indicator gives maintenance personnel a clear visual reference during inspection and troubleshooting.
ā” 6A Rating
Protects a correctly sized circuit rated for 6A
š 2 Poles
Provides 2-pole protection for a properly designed two-conductor branch
š”ļø 10kA Capacity
Offers 10kA short-circuit breaking capacity for suitable electrical systems
ā
UL 489 Approved
Approved for branch-circuit protection when selected and installed correctly
ā ļø Verify the Complete 6A 2-pole Circuit Design
Do not select this breaker from current rating alone. Confirm the 6A rating, 2-pole configuration, conductor current, load requirements, 480Y/277V AC or 96V DC rating, available fault current, C trip curve, ambient conditions, and applicable electrical codes before installation.
š 6A C-Curve Magnetic Trip Range
The C-curve magnetic element operates at 5ā10 times rated current. For the UB10C2006A, that corresponds to a specified instantaneous magnetic range of approximately 30ā60A. The thermal element provides overload response below severe fault levels. Always confirm coordination with normal startup current and upstream or downstream protective devices.

š 2-pole Breaker Selection and Installation Overview
1. Calculate the Load: Confirm that conductor current and connected equipment are compatible with a 6A protective device.
2. Verify Pole and Voltage Requirements: Confirm that the circuit requires 2 poles and operates within the 480Y/277V AC or 96V DC rating.
3. Check Fault and Inrush Current: Verify the available fault current, 10kA breaking capacity, and compatibility of the C curve with normal startup demand.
4. Mount and Terminate: Install on DIN rail using conductors within the specified 18ā3 AWG range and apply the listed 2.5 Nm terminal torque.
5. Inspect Before Energizing: Verify wiring, labeling, protective-device coordination, and code compliance before commissioning.
Circuit-breaker selection and installation must be completed by qualified personnel in accordance with the equipment documentation and applicable electrical codes.
