1489-M1C200 | Allen-Bradley Miniature Circuit Breaker, 1 Pole, Trip Curve C, 20A

The 1489-M1C200 is a miniature circuit breaker (MCB) designed to protect electrical circuits from overcurrent conditions such as overloads and short circuits. It is commonly used in control panels, distribution boards, and machinery. This device interrupts the current flow when excessive current is detected, helping to prevent damage to equipment and reduce fire risk. It’s suitable for both residential and industrial applications. Allen-Bradley ensures its durability and performance under international standards.

This breaker is designed for DIN rail mounting, allowing fast and secure installation in standard enclosures. DIN rail mounting also facilitates easy replacement and modular assembly. It’s a common method in industrial automation panels and residential systems. The compact design saves space while maintaining accessibility. The unit locks onto the rail with a reliable latch mechanism.

Yes, it can operate in DC systems up to 48V DC, making it versatile for control circuits and low-voltage DC applications. It provides the same overcurrent protection in DC as it does in AC systems. However, the breaking capacity and arc suppression are specially designed for DC operation. Care must be taken with polarity in DC wiring. Always verify compatibility with DC-rated loads before installation.

The 1489-M1C200 is a 1-pole circuit breaker, which means it protects a single-phase line. This is ideal for most standard branch circuits, lighting loads, or individual motor feeds. Single-pole breakers are efficient for compact wiring solutions. It interrupts one conductor and is typically used in low-voltage systems. Its simple design ensures straightforward wiring and maintenance.

Yes, the 1489-M1C200 is currently in production and widely available. It is part of Allen-Bradley’s active product line and complies with current UL and IEC standards. There are no indications that it is being phased out. Should it be discontinued in the future, equivalent models like the 1489-M1C series with the same trip curve and current rating can serve as direct replacements. Always check Rockwell Automation's lifecycle status for the latest update.
