Product FAQs
5 answersWhat is the direct replacement for the legacy 1489-A1C100 circuit breaker?
The 1489-A1C100 has been superseded by the Allen Bradley 1489-M1C100. The updated 1489-M series maintains the same UL 489 branch circuit rating, 10A capacity, and C-curve trip profile for seamless integration into existing panels.
What type of trip curve does the 1489-A1C100 feature?
This breaker utilizes a C-curve trip profile. It is engineered to handle moderate inrush currents without nuisance tripping, which is typical for small control circuits, lighting loads, and auxiliary equipment.
Does the 1489-A1C100 provide branch circuit protection or supplementary protection?
As part of the Bulletin 1489-A series, this device is UL 489 listed for branch circuit protection. It can be used as a primary overcurrent protective device, unlike UL 1077 breakers which are limited to supplementary protection.
What type of enclosures or panels are compatible with the 1489-A1C100?
This miniature circuit breaker is designed for high-density industrial control panels and motor control centers. It snaps directly onto standard 35mm DIN rails, making it ideal for space-constrained modular assemblies.
How does the thermal-magnetic trip mechanism function on this breaker?
The fixed thermal-magnetic design provides two layers of protection. The thermal element offers delayed tripping for sustained overloads, while the magnetic element provides instantaneous tripping to quickly isolate short circuits and prevent equipment damage.
