1489-M1C020 | Allen-Bradley Miniature Circuit Breaker, 1 Pole, Trip Curve C, 2A

This MCB supports various voltage ratings depending on standards:

• 240V AC and 48V DC under UL/CSA standards.
• 230V AC according to IEC/EN standards.
• 277V AC is also listed under general specifications.

These ratings make it compatible with a wide range of control systems globally.

Yes, its miniature form factor is designed for compact installations. It conserves space while allowing for multiple breakers to be mounted side-by-side. Its DIN-rail mounting compatibility further simplifies integration into dense control cabinets. This helps reduce overall panel size and improves installation flexibility.

Installation is straightforward:

• Mounts easily on standard DIN rails.
• Connect input and output terminals using proper torque values.
• Label the circuit clearly for maintenance purposes.
• Combine with other 1489 series breakers for modular setups.

Always consult Allen-Bradley’s installation guide for safe and compliant mounting.

Yes, this breaker handles both types of current:

• Rated up to 240V AC for branch circuit applications.
• Supports DC voltages up to 48V for control or signaling systems.
• DC use must observe polarity and wiring guidelines.
• Effective tripping remains consistent under either AC or DC use.

This dual compatibility adds flexibility for engineers and panel designers.

Yes, the 1489-M1C020 remains in active production and is readily available through Allen-Bradley’s authorized distribution channels. It continues to be supported with documentation, accessories, and compatibility updates. Buyers can confidently integrate it into new projects or use it as a replacement in existing systems.
