Circuit Breakers

Circuit breakers are safety devices that damage or tear electrical circuits due to an overload of electricity or other potentially hazardous events. The Type 219-3-2988-928 circuit breaker is a thermal magnetic circuit breaker designed for the protection of low voltage, direct current installations. The breaker performs the task of automatic short circuit and overload protection, as well as providing manual control operations.

Application Field

The Type 219-3-2988-928 circuit breaker is designed for applications in both domestic and industrial environments. It is ideal for providing protection for direct current (DC) motor systems and starting systems. Its compact size makes it excellent for thermal protection of transformers, branch circuits, DC supplies, and AC supplies. It can also be used for motor circuits, AC lighting, circuits, contactors, and motor controllers.

Working Principle

The Type 219-3-2988-928 circuit breaker is a thermal magnetic circuit breaker which utilizes both thermal and magnetic principles to provide overload and short circuit protection. The thermal component of the breaker is activated when an overload or short circuit current is detected. The magnetic component also senses the current level and trips the breaker when the current exceeds the tripping threshold.

When the current reaches the set tripping threshold, the thermal component activates a bimetal which deforms and breaks the circuit. At the same time, the magnetic component triggers a relay. The relay then triggers the breaker, de-energising the circuit by opening the contactor and thereby preventing an unsafe flow of current.

The Type 219-3-2988-928 circuit breaker can detect both overloads and short circuits, making it an ideal choice for protection against both current levels. It is manually adjustable, making it easy to set the desired current tripping threshold. The breaker is also resettable, meaning it can be used multiple times in the case of multiple overloads or short circuit events. Additionally, it can be installed and maintained without any special tools.

Safety Features

The Type 219-3-2988-928 circuit breaker is rated for protection against electrical shocks and hazardous environments. The housing is dust-proof and corrosion protected, and the breaker also includes an electromagnetic interference shield for added protection. In the event of a short circuit, the breaker immediately trips and breaks the circuit to protect against further damage.

The breaker is also designed with a manual reset switch that can be used to easily reset the breaker in the event of an overload. The reset switch can also be used to manually trip the breaker in the case of an emergency. This switch is made from a polyamide material that is highly resistant to fire and chemical corrosion.

Conclusion

The Type 219-3-2988-928 circuit breaker is a thermal magnetic circuit breaker designed for the protection of low voltage, direct current installations. It is ideal for providing protection against both overloads and short circuits due to its dual thermal and magnetic capabilities. The breaker is manual adjustable, resetable, and easy to install and maintain without any special tools. It is also rated for protection against electrical shock and hazardous environments.
