IMO UB10C2008A 8 Amp 2 Pole Miniature Circuit Breaker: UL 489, C Curve, 10kA
DIN rail mount miniature circuit breaker for industrial branch circuit protection. Rated for 8 amps, 480Y/277VAC or 96VDC with two-pole switching, C-curve tripping and a 10kA short circuit breaking capacity.
✅ Designed for Industrial Branch Circuit Protection
The
IMO Precision Controls UB10C2008A is designed to protect low-current electrical circuits against overloads and short circuits. Its 8 amp rating and two-pole configuration make it suitable for control panels and electrical distribution systems that require simultaneous protection across two conductors.
The breaker uses a C tripping curve, allowing it to tolerate the moderate startup current commonly produced by transformers, relays, contactors and small motor loads without sacrificing dependable fault protection.
Reliable 8 Amp Protection for Industrial Control Panels
The
IMO UB10C2008A miniature circuit breaker provides thermo-magnetic protection for industrial control panels, machine automation equipment and electrical distribution applications. Thermal tripping responds to sustained overload conditions, while magnetic tripping isolates high-current faults rapidly to help limit equipment damage.
With a
10kA short circuit breaking capacity, UL 489 approval and ratings up to 480Y/277VAC or 96VDC, the UB10C2008A provides dependable branch circuit protection in a compact DIN rail package. A built-in contact position indicator allows technicians to confirm breaker status during installation, inspection and troubleshooting.

✅ Why Choose the UB10C2008A?
The UB10C2008A combines UL 489 branch circuit approval, a 10kA interrupting rating and C-curve performance in a compact two-pole breaker. It is a practical choice when a control panel requires reliable 8 amp protection without using unnecessary enclosure space.
⚠️ Installation Requirements
Qualified installation: Installation and servicing should be completed by qualified electrical personnel in accordance with applicable electrical codes.
Verify ratings: Confirm that the breaker current, voltage, pole configuration and interrupting capacity match the circuit requirements before installation.
Terminal torque: Tighten conductors to the specified 2.5 Nm (22.2 lb-in) fastening torque.
🔧 Thermo-Magnetic Protection
Thermal protection: Responds to sustained overloads that can overheat conductors and 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: Accommodates moderate equipment startup current while maintaining dependable overcurrent protection.
🏭 Common Applications
The IMO UB10C2008A can protect branch circuits inside industrial control panels and OEM machinery where a two-pole, 8 amp breaker is required. Its C-curve response also makes it suitable for control circuits that power relays, transformers or small motors with moderate startup current.
Other suitable installations include machine automation systems, electrical distribution equipment and panel-mounted control assemblies operating within the breaker’s specified voltage, temperature and fault-current ratings.
