Circuit Breakers symbols for use in electrical, pneumatic and hydraulic schematic diagrams. Available in SVG, PNG, JPG, DXF & DWG formats The symbolic representation of a fast blow fuses in any electrical circuit. Fast blow fuse instantly blow when the current exceeds beyond its maximum limit. It is the most common type of fuse used in electrical equipment which are sensitive to high current. Slow Blow Fuse

EXPLANATION Transformer Represents a variety of transformers from liquid-filled to dry-types. Additional information is normally printed next to symbol indicating winding connections, primary/secondary voltages, impedance and kVA or MVA ratings. Removable/Drawout Circuit Breaker Normally represents a drawout circuit breaker 5 kV and above. 52 42 - Running Circuit Breaker. 43 - Manual Transfer or Selector Device. 46 - Reverse-phase or Phase-Balance Relay. 47 - Phase-Sequence Voltage Relay. 48 - Incomplete-Sequence Relay. 49 - Machine or Transformer Thermal Relay. 50 - Instantaneous Overcurrent. 51 - AC Time Overcurrent Relay. 52 - AC Circuit Breaker. 1200 A Identifies the drawout circuit breaker represented by the symbol as a 1200 ampere circuit breaker. 225 A/3P Indicates the fixed circuit breaker represented by the symbol as a 225 ampere, three-pole breaker. Indicates that the transformer represented by the symbol is connected delta-wye. Standardized circuit breaker symbols allow electrical and building plans to clearly represent the presence and attributes of circuit breakers across systems. Consistent use of approved symbols ensures accurate interpretation of diagrams by all stakeholders. Adhering to ANSI/IEEE or IEC industry standards for symbols maximize clarity.

Low-voltage <1000 V circuit breakers are represented by the first two of the following symbols shown in Figure 3. Figure 3 - Circuit Breaker Symbols Medium-voltage circuit breakers shown on a one-line typically incorporate the Basic Square Breaker symbol with the ANSI Device Number 52 inside. One of the most important symbols is the "on" and "off" switch. This symbol is pretty self-explanatory and is typically denoted by an "I" and "O" for "on" and "off," respectively. It's essential to know which way to flip the switch when dealing with a tripped circuit breaker. circuit breakers all symbols > electrical installations > switchgear and protective devices (ANSI) > protective devices > circuit breakers circuit breaker 3P circuit breaker with magnetic overload device 3P circuit breaker with magnetic overload device circuit breaker with thermal overload device 3P (form 1) Electronic symbol An air circuit breaker for low-voltage (less than 1,000 volt) power distribution switchgear Four one-pole miniature circuit breakers Electrical installations Wiring practice by region or country North American practice United Kingdom practice Regulation of electrical installations BS 7671 UK wiring regulations

The most common symbol used to represent a circuit breaker is a large red circle with a small black line. This indicates a standard general-purpose circuit breaker, which is rated for currents up to 300 amps. The most common types of circuit breakers include thermal-magnetic, miniature, and high-voltage. Whenever a fault occurs, the trip coils get energized the moving contacts get pulled by some mechanism, and therefore, the circuit breaker is opened and the circuit is broken. Figure 1 shows the parts of a typical oil circuit breaker. Symbol of Circuit breaker. The circuit breaker symbol is shown below. Types of Circuit breaker
Typical Circuit Breaker Nameplate IEC 60947 is the circuit breaker standard and covers the marking of breakers in detail. Any manufacturer following this standard should comply with the markings.. by symbol ; reference temperature for non-compensated thermal releases, if different from 30 °C ; Additional Circuit Breaker Information.
