He is often depicted as a beautiful youth, in keeping with the notion of the sense of freshness and newness of such liberating awareness, and is seated cross-legged on a lotus-flower throne, attired in princely silks and ornaments. In his right hand, raised above his head, he wields the symbol most distinctively his, a flaming sword of wisdom that cuts through the ignorance which binds sentient beings to a cycle of suffering and unhappiness. In his left hand, at his heart, he holds a book, a volume of the Perfection of Wisdom, representing both the source and embodiment of his awakened understanding.

Circuit breakers are also rated by the maximum fault current that they can interrupt; this allows use of more economical devices on systems unlikely to develop the high short-circuit current found on, for example, a large commercial building distribution system.

In the United States, Underwriters Laboratories UL certifies equipment ratings, called Series Ratings or "integrated equipment ratings" for circuit breaker equipment used for buildings. Power circuit breakers and medium- and high-voltage circuit breakers used for industrial or electric power systems are designed and tested to ANSI or IEEE standards in the C37 series.

This low voltage power circuit breaker can be withdrawn from its housing for servicing. Trip characteristics are configurable via DIP switches on the front panel. Many classifications of circuit breakers can be made, based on their features such as voltage class, construction type, interrupting type, and structural features.

Low-voltage circuit breakers[ edit ] Low-voltage less than 1, VAC types are common in domestic, commercial and industrial application, and include: Miniature circuit breaker MCB —rated current not more than A. Trip characteristics normally not adjustable. Thermal or thermal-magnetic operation.

Breakers illustrated above are in this category. Trip current may be adjustable in larger ratings. Low-voltage power circuit breakers can be mounted in multi-tiers in low-voltage switchboards or switchgear cabinets.

The characteristics of low-voltage circuit breakers are given by international standards such as IEC These circuit breakers are often installed in draw-out enclosures that allow removal and interchange without dismantling the switchgear.

Large low-voltage molded case and power circuit breakers may have electric motor operators so they can open and close under remote control. These may form part of an automatic transfer switch system for standby power.

Low-voltage circuit breakers are also made for direct-current DC applications, such as DC for subway lines. Direct current requires special breakers because the arc is continuous—unlike an AC arc, which tends to go out on each half cycle.

A direct current circuit breaker has blow-out coils that generate a magnetic field that rapidly stretches the arc. Small circuit breakers are either installed directly in equipment, or are arranged in a breaker panel.

Inside of a circuit breaker The DIN rail -mounted thermal-magnetic miniature circuit breaker is the most common style in modern domestic consumer units and commercial electrical distribution boards throughout Europe.

The design includes the following components: Actuator lever - used to manually trip and reset the circuit breaker. Most breakers are designed so they can still trip even if the lever is held or locked in the "on" position. This is sometimes referred to as "free trip" or "positive trip" operation.

Actuator mechanism - forces the contacts together or apart.Security. MCB will never ask for your login details by email. Report any suspicious email, website, or unsolicited request that.
