Circuit Breakers

295-11-1REC5-37774-3 is an electrical protection device used to safeguard electrical systems from damage due to overloads and short circuits. Circuit breakers protect by cutting off electrical power when the circuit is overloaded or short circuited, thereby preventing further damage to the electrical system. This type of circuit breaker has a wide range of applications and is used in many different types of electrical systems.

Application Field

The 295-11-1REC5-37774-3 is mainly used in low-voltage, single-phase, residential and commercial applications. This type of circuit breaker is a good choice for applications where there is a potential for occasional overloading of the circuit, as well as for backup protection in the event of a short circuit. It is also suitable for use in appliances, industrial machines, and electronic equipment.

This circuit breaker is especially popular in North America, as it is approved by the National Electrical Code (NEC) and meets the Underwriters Laboratories (UL) Standard 489-M. Moreover, it has also been designed to meet the requirements of the Canadian Standards Association (CSA).

Working Principle

The 295-11-1REC5-37774-3 utilizes both thermal and magnetic action to break the circuit. When the current running through the breaker exceeds its rating, the thermal element begins to heat up. This causes the trip lever connected to the thermal element to reach a preset temperature and trip the breaker. The magnetic component is activated once the trip lever is in the trip position, causing an arc to be drawn across the contacts, effectively breaking the circuit.

In the event of an overload, the trip lever will move to the trip position and open the contacts, interrupting the flow of electricity and preventing further damage to the electrical system. Once the circuit breaker has tripped, it must be manually reset. This can be done by pushing the reset button, rotating the reset lever, or using a key to reset the breaker.

When the current running through the circuit normalizes and no longer exceeds the circuit breaker\'s rating, the breaker can be reset and the electrical power can flow once again.

It is important to note that the 295-11-1REC5-37774-3 is not able to reset itself if the cause of the trip is not found and corrected first. For this reason, it is important to rule out any potential causes of the trip before resetting the circuit breaker.

In conclusion, the 295-11-1REC5-37774-3 is a reliable and popular circuit breaker. It is designed to protect an electrical system from overloads and short circuits, and has been approved by the NEC in North America. This type of circuit breaker utilizes both thermal and magnetic action to break the circuit, and must be manually reset after tripping the breaker.
