1489 Thermal-Magnetic Circuit Breakers. Bulletin 1489-M Thermal-magnetic Circuit Breakers are UL 489 Listed for branch circuit protection in the United States and Canada, and they are certified as Miniature Circuit Breakers for IEC applications. These circuit breakers are ideal for extreme ambient conditions, feature fast breaking time, and superior shock and vibration resistance.

Use the following steps to determine the current rating for the breaker. 1. Take the rated current of the equipment. For example, 10 A. 2. Take the ambient temperature of the 1492-SP location (e.g., 50 °C (122 °F)). 3. Refer to the table below, which rerates the 1492-SP current for the given ambient temperature.

This document assists the designer of a control system in choosing an Allen-Bradley Molded Case Circuit Breaker (MCCB) or Miniature Circuit Breaker (MCB) for proper coordination in main (primary) and branch circuits. You can choose either Selective Protection or Back-up Protection based on these tables in this publication.

definitions for circuit breakers. A circuit breaker’s primary function is to protect wire. In North America, the term ‘circuit breaker’ generally refers to a device that is a UL489 / CSA 22.2 No. 5 constructed device. In other parts of the world, there are other guidelines

1489-M Thermal-magnetic Miniature Circuit Breakers, 1489-M miniature circuit breakers (MCBs) can be used in the 1-po le version up to 48V DC and the 2-pole version with series conn ection of the two poles up to 96V DC. If voltages to earth exceeding 48V DC occur, see the 2-pole version of Bulletin 1489-M for 1-pole disconnection.

A type MCB – Miniature Circuit Breaker is highly sensitive to the short circuit, and hence we can find its application in the manufacturing of semiconductors. B Type MCB trips off the circuit when the current exceeds 3-5 times the current flow and finds its application in cable protection. C Type MCB trips off the circuit when the current

Rockwell can provide various circuit breaker of different configurations, voltage ranges and current ranges to meet customer requirements, including, Allen-Bradley miniature circuit breakers (Rockwell MCB, Allen Bradley MCB, AB MCB) including series Bulletin 1489-M, Bulletin 188-J&188-K, etc.
