A2: 50 Instantaneous Overcurrent Protective Relay Emergency Generator Commonly used electrical symbols The device number designates the relay type (50 = instantaneous overcurrent, 59 = overvoltage, 86 = lockout, and so on). The symbol is frequently shown in conjunction with a transfer switch.

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 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. 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.

A circuit breaker is defined as a switching device that can be operated manually or automatically for controlling and protecting an electrical power system. It consists of two main contacts: a fixed contact and a moving contact. The contacts are normally closed and allow current to flow through the circuit. 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.

symbols (such as j, exp, Cu) are used to indicate mathematical operations, chemical elements etc. Frequently occurring technical phrases are commonly rendered as abbreviations (such as e.m.f., p.d.). In circuit diagrams, graphical symbols identify network components and devices. Electrical Symbols - OVERCURREMT CIRCUIT BREAKER. Circuit breaker (overcurrent circuit breaker, installation circuit breaker type DS) - an element of electrical installation, which breaks the circuit when the current flowing in the circuit exceeds the safe value for this circuit. These circuit breakers are intended for control and protection against overloads (overloads and short circuits.
