Circuit breakers are a form of electrical protection device that’s designed to protect electrical circuits from being damaged by overcurrent or from being overloaded. The W93-X1110-20 is a model of circuit breaker designed to provide overcurrent and overload protection. In this article, we’ll take a look at the application field and working principle of the W93-X1110-20 circuit breaker.

The W93-X1110-20 circuit breaker is designed for overcurrent and overload protection of residential, commercial and industrial applications. It is suitable for AC 50/60Hz circuit with rated voltage up to 250V and household appliances, lighting fixtures, electric motor power control, and power distribution in building facilities. It is UL listed and meets the requirements for a variety of national and international standards, including UL 489, IEC 60947-2, and CSA C22.2.

The W93-X1110-20 circuit breaker is designed with a thermally operated switch mechanism that is activated by heat due to an overload. The current rating indicates the value of current that the circuit breaker is designed to safely interrupt. When an overload current occurs, the heat generated is higher than normal, and the switch contact separator will move to open the circuit and the breaker trips. The reset button must be manually reset after the afromentioned overheated condition to return the circuit breaker to its normal state.

The W93-X1110-20 circuit breaker comes with a UL listed lockable switch. This lockable switch prevents unauthorized personnel from tampering with the device, thereby providing an additional layer of safety. In addition, the circuit breaker has a visible trip indicator on the handle, which indicates whether the device has been tripped during an overload or short circuit.

The W93-X1110-20 circuit breaker has a double overload protection design to improve its service life and reduce the risk of damage due to over-current and overload. It uses heaters to provide an additional layer of protection by thermal trip. This design helps protect against unexpected overloads that can cause fires or burnout motor insulation. To further increase the lifespan of the breaker, it is designed with a contact uniformity, which ensures that contacts remain clean and efficient during operation.

In short, the W93-X1110-20 circuit breaker is designed to provide overcurrent and overload protection for a variety of residential, commercial and industrial applications. It is UL listed and meets the requirements for a variety of national and international standards. It is designed with a thermally operated switch mechanism that is activated by heat due to an overload and is further protected with a double overload protection design for increased safety. Additionally, it is designed with a visible trip indicator to indicate when it has been tripped and is fitted with a lockable switch to prevent unauthorized tampering.
