Circuit Breakers: R11-2-.750A-B 121EV Application Field and Working Principle

In this article we will focus on the application field and working principle of the R11-2-.750A-B 121EV circuit breaker. One of the most important advances of this circuit breaker is its ability to provide reliable protection for residential and commercial wiring applications at a reasonable cost. It is also suitable for use in hazardous locations where flammable materials are present.

The R11-2-.750A-B 121EV circuit breaker has a trip rating of 13 kiloamps, a 30 amp instantaneous trip rating, and a 150 volt power supply requirement. It is designed for a variety of applications and can handle a variety of circuits. It is also certified for UL listing. This UL listing is an important safety feature, ensuring that it is capable of protecting against arcing or electrical shorts.

The device features manual overload and lockout features, both of which can be used to prevent damages caused by overcurrent. The lockout feature prevents the circuit breaker from being reset until the overload condition has been cleared, thus preventing the possibility of further damage. Additionally, the thermally sensitive element contained in the breaker will open the circuit in the event of an over current or short circuit.

The R11-2-.750A-B 121EV circuit breaker is designed for a variety of applications, and is suitable for use in residential, commercial and industrial settings. This type of circuit breaker is typically used in applications where an extended short circuit can cause a considerable amount of damage, such as motors, transformers and air conditioning units. Additionally, the device is suitable for use in hazardous locations, ensuring that the circuit breaker will protect against dangerous conditions.

The device operates on the principle of an electrical switch that is opened when an electrical overload or short occurs. When the switch is opened, it interrupts the power flow and eliminates the possibility of damage to connected equipment. As the switch trips, a spring on the switch arm pushes against a stopper to close the switch.

The trip point of the switch is adjustable and can be adjusted using a manual thumb-ratchet screw (adjustable range 0.12A-0.50A). The spring force of the manual thumb-ratchet screw is adjustable to match the breaker\'s current rating. Additionally, the contacts of the breaker feature spring damping to ensure that the opening and closing action is smooth and accurate.

To ensure optimal performance, the R11-2-.750A-B 121EV circuit breaker is designed with modern insulation technology. Its insulation is designed with advanced thermal protection that protects against overheating. In addition, it is designed to operate in high vibration, shock and extreme environmental conditions. Its use of superior materials ensures that it is suitable for use in harsh environments and is reliable in protect against short circuits, overloads and other hazardous conditions.

In conclusion, the R11-2-.750A-B 121EV circuit breaker is a reliable and cost-effective solution for residential, commercial and industrial applications. With its adjustable trip point and thermal protection, this breaker is capable of providing reliable protection against a variety of hazard conditions. Additionally, its design features ensure that it is suitable for use in hazardous locations, making it an ideal solution for protecting against arcing and electrical shorts. Finally, its use of superior materials ensures that it will withstand vibration, shock and extreme environmental conditions.
