Why Choose the IMO UB10D101.6A Miniature Circuit Breaker?
The IMO UB10D101.6A is a compact UL 489 miniature circuit breaker (MCB) engineered to provide reliable overload and short-circuit protection for industrial control systems, machinery and electrical installations. As part of the trusted IMO UB10 series, this single-pole device delivers dependable branch circuit protection for low-current industrial applications.
Featuring a D curve tripping characteristic, the UB10D101.6A is ideally suited to circuits supplying transformers, switched-mode power supplies, contactors, solenoids and other inductive equipment that generate high temporary inrush currents. Its thermo-magnetic operating mechanism provides rapid fault isolation while helping to minimise nuisance tripping during normal equipment energisation.
With a 1.6 A rated operational current, a single-pole configuration and a 10 kA short-circuit breaking capacity, the IMO UB10D101.6A is ideal for protecting sensitive control and auxiliary circuits. Its compact DIN rail mounted design enables straightforward installation inside industrial control panels, machinery cabinets and electrical enclosures.

Reliable Protection for High-Inrush Control Circuits
Miniature circuit breakers automatically disconnect electrical circuits when overload or short-circuit conditions occur, helping to protect conductors, control devices and connected equipment from electrical damage. This improves operational safety, reduces downtime and simplifies system recovery once a fault has been cleared.
The D curve response of the IMO UB10D101.6A allows correctly designed circuits to tolerate temporary current peaks of approximately 10 to 20 times the rated current before instantaneous magnetic tripping occurs. This makes it particularly suitable for inductive equipment with significant energisation currents.
Typical Applications
- Industrial control and auxiliary circuits.
- Control transformers and switched-mode power supplies.
- Solenoid, relay and contactor circuits.
- PLC and factory automation panels.
- OEM machinery and production equipment.
- Electrical cabinets and distribution enclosures.
