Product Description

Allen-Bradley 1489-M1C250 25A UL489 DIN Rail Circuit Protection

The Allen-Bradley 1489-M1C250 is a Bulletin 1489-M series miniature circuit breaker engineered for dependable branch circuit protection in North American and IEC-based industrial systems. This 1-pole, 25 amp device uses a C-curve thermal-magnetic trip mechanism to protect wiring and connected equipment from overloads and short circuits.

UL489-Listed Thermal-Magnetic Protection

  • 25 amp rated current with C-curve tripping characteristics
  • UL 489 and CSA certified for branch circuit protection
  • Current-limiting design to reduce let-through energy
  • Red/green mechanical indicator for contact status visibility

DIN Rail Architecture for Control Panels

This breaker mounts directly to standard 35 mm DIN rail and features dual terminals that support wire or bus bar connections. Reversible line and load orientation allows flexible panel layouts while maintaining compliance with industrial wiring practices.

Industrial Applications

  • Industrial control panels and automation systems
  • Branch circuit protection for power distribution
  • Transformer, heater, and general load protection
