US10D2001A IMO 10kA UL1077 MCB 2 pole 1A D Curve

Why Choose the IMO US10D2001A Miniature Circuit Breaker?

The IMO US10D2001A is a compact and dependable UL1077 supplementary miniature circuit breaker (MCB) designed to protect industrial control circuits, machinery and automation equipment against overload and short circuit conditions. Manufactured by IMO Precision Controls, it provides reliable electrical protection in a space-saving DIN rail-mounted format.

The US10D2001A features a 10 kA short circuit breaking capacity and a D curve tripping characteristic. This operating curve allows the breaker to tolerate higher temporary inrush currents, making it particularly suitable for transformers, motors, solenoids and other inductive electrical loads.

With a rated current of 1 A and a 2 pole configuration, the IMO US10D2001A is ideal for protecting low-current circuits where simultaneous isolation of two conductors is required. Its compact construction and straightforward DIN rail installation make it a practical solution for panel builders, machine manufacturers and industrial automation engineers.

Reliable Protection for Industrial Control Circuits

Supplementary miniature circuit breakers help protect electrical equipment by automatically interrupting the circuit when excessive current or a short circuit is detected. This can reduce equipment damage, improve system reliability and simplify the restoration of a circuit after a fault has been resolved.

The D curve response of the IMO US10D2001A is particularly useful in circuits where brief but substantial starting currents are expected. It helps prevent unnecessary tripping during normal equipment start-up while maintaining dependable protection against sustained overcurrent and fault conditions.

Typical Applications

• Industrial control panels and electrical cabinets.
• Machine building and OEM equipment.
• Transformer and power supply circuits.
• Motor control and automation systems.
• Solenoid and inductive load circuits.
• Manufacturing and processing machinery.
