Rated Current (A) Rated Current (A) Coil Resistance at 25 C Curves AD, MD 0.00 Coil Resistance (Ω) Curves AA, BA, MA Voltage Drop Due to Resistance or Impedance The internal resistance or impedance of a circuit breaker tends to be larger for a smaller rated current. Therefore, when circuit breakers with a small rated current are used, voltage drop should be taken into consideration. Internal resistance also varies with time delay curves, even at the same rated current. This should also be considered during installation Impedance (Ω) Time Delay Curve and Ambient Temperature Since RA series circuit breakers employ an electromagnetic tripping system, the rated current (trip current) is not affected by the ambient temperature, but the time delay varies with the oil viscosity in the tube. Lower oil viscosity at higher temperatures results in shorter delay; whereas at lower temperatures, the delay will be prolonged. The time delay curves, shown starting on page - 7, are at 25 C. Time delay curves can be corrected.

Voltage Drop Due to Coil Impedance The internal impedance of a circuit breaker tends to be larger for a smaller rated current. Therefore, when low rated circuit breakers are used, the voltage drop should be taken into consideration.

29 Instructions Instructions: All Series General IDEC s circuit breakers have been developed for the protection of electrical circuits and small-sized electrical equipment and provide excellent protection against overloads and short-circuits. Additionally, IDEC s circuit breakers are designed to suit specific needs. Each series offers unique circuit protection characteristics and a choice of actuator styles. IDEC s Circuit Breaker Features Various models are available with different internal circuits, tripping characteristics, and rated currents - to 3- multi-pole Inertia delay Auxiliary contacts and alarm contacts The electromagnetic tripping system is not affected by ambient temperature Safe trip-free mechanism Vibration- and impact-resistant design When using accessories such as plug-in bases, flush plates, and colored caps, a variety of mounting styles is possible such as DI rail mounting, snap mounting into panel cut-outs, and color-coded arrangement on the panel Mounting Instructions: Installation Angle Designed to be mounted on a vertical surface, the circuit breakers should be mounted on a surface within of the vertical plane. If the circuit breaker is mounted on a horizontal surface or at any angle other than the specified angle, its characteristics will be changed. Multi-Pole Assemble Multi-pole types such as 2- or 3-pole should be assembled by IDEC. Because of their characteristics, -pole breakers cannot be combined to produce multi-pole units. Applications The IDEC RA circuit breaker series features superior overload and short-circuit protection. Many combinations of protection mechanisms and internal circuit connections enable wide applications. Precision measuring instruments: electronic counters, projection instruments, oscilloscopes, industrial instrumentation, and analytic devices Electronic communication devices: facsimile machines, computers, recorders Industrial machinery: printers, elevators, cranes Chemical and food industry machines: vacuum devices, wrappers, centrifuges, agitators Machine tools: mill grinders, drills, presses Business machines: automatic vendors, medical equipment, beauty salon equipment, entertainment games Other: office equipment, air-conditioners, conveyor belts, and many more How the Breaker Operates IDEC s hydraulic magnetic circuit breakers operate like a solenoid coil. The coil unit consists of an oil-filled tube with a metal core at one end and a pole piece and armature at the opposite end with a spring in between. When a current load passes through the coil winding, it creates a magnetic field. As long as the current load is either at or below the nominal rating of the breaker, the metal core will remain stationary. If the current load increases beyond the nominal rating, the strength of the magnetic field causes the core to move toward the pole-end of the tube. The oil viscosity regulates the core s movement through the tube, thereby regulating the time delay. As the percentage of current load increases, the required trip time of the breaker decreases and vice versa. When the current reaches the overload rating, the metal core will meet the pole piece at the opposite end of the tube. At this point, the armature is attracted to the same pole piece, tripping the breaker. In case of sudden short circuit, the magnetic field created will instantly trip the breaker. Internal Circuits Overview Description Circuit Example Load Series Trip This is the most common circuit breaker, providing excellent overload and short circuit protection. It can also be used as an O/ switch. Load B Load B Load A Load A Series Trip with Auxiliary Contact Since the auxiliary contact operation is interlocked with the O/ of the main contactor, circuit breaker operation can be monitored by a lamp or buzzer. This circuit breaker can also be used to control auxiliary circuits up to 250V AC/5A (resistive load). Series Trip with Alarm Contact Since the alarm contact is electrically independent of the main contactor, but actuates when the protective element operates. The alarm can be used with a lamp or buzzer to monitor trip operations, and can also be used for controlling alarm circuits. The contact rating is 250V AC/5A (resistive load).
