UB10D100.5A IMO 10kA UL489 MCB 1 pole 0.5A D Curve

Why Choose the IMO UB10D100.5A Miniature Circuit Breaker?

The IMO UB10D100.5A is a compact and dependable single-pole miniature circuit breaker (MCB) designed to protect industrial control circuits, machinery and electrical equipment against overloads and short circuits. As part of the IMO UB10 circuit breaker series, it provides reliable branch circuit protection for low-current industrial applications.

This circuit breaker features a D curve tripping characteristic, making it suitable for equipment that can produce high temporary inrush currents during energisation. Typical loads include transformers, power supplies, solenoids, contactors and other inductive devices used in industrial automation and machine-control systems.

With a rated current of 0.5 A, a single-pole configuration and a 10 kA short-circuit interrupting capacity, the UB10D100.5A is ideal for protecting sensitive auxiliary and control circuits. Its compact DIN rail mounted construction enables straightforward installation inside electrical control panels, machinery cabinets and distribution enclosures.

Key Advantages

• Dependable overload and short-circuit protection for low-current circuits.
• 0.5 A rated current suitable for sensitive control and auxiliary equipment.
• Single-pole configuration for individual circuit protection.

Reliable Protection for Low-Current Control Circuits

Miniature circuit breakers automatically disconnect electrical circuits when excessive current or a short circuit is detected. This helps protect conductors, control components and connected equipment from electrical damage while improving installation safety and reducing the risk of equipment downtime.

The D curve response of the IMO UB10D100.5A allows the breaker to tolerate short-duration current surges that can occur when energising transformers, solenoids and industrial power supplies. Its low 0.5 A rating makes it particularly suitable for protecting sensitive control circuits where accurate overcurrent protection is required.

Typical Applications

• Industrial control and auxiliary circuits.
• Transformers and industrial power supplies.
• Solenoids, contactors and electromagnetic loads.
• PLC and automation control panels.
• OEM machinery and production equipment.
• Electrical distribution and machinery cabinets.
