Circuit Breakers are an important aspect of electricity generation, distribution, transmission, and consumption. They provide protection to the electrical infrastructure and provide a way to safely and efficiently manage the current flow. The JTMP-2-1RLS4R-31615-400S circuit breaker belongs to the family of molded case circuit breakers. It is used for applications typically in industrial or commercial facilities, including motor control centers, panel boards, switchboards, and other similar applications. The short circuit current rating of the breaker is up to 15KA, with an interrupting rating of up to 400A.

A circuit breaker is an electromechanical device designed to interrupt the flow of electric current in the event of an overload or short circuit. When an overload or short circuit is detected, an electric current flows through a solenoid, which then produces a strong magnetic field. This magnetic field actuates a mechanical switch, which opens the contacts of the circuit and shuts down the flow of electric current.

The JTMP-2-1RLS4R-31615-400S breaker is a trip unit with thermal-magnetic protection. It is designed with two distinct current sensing elements; the thermal element and the magnetic element. The thermal element is used to detect overloads and slow short-circuit currents, which allow the breaker to respond to both overloads and sustained short-circuit currents. The magnetic element is designed to respond to very fast short circuits, which could result in catastrophic damage and/or injury. When activated, the breaker trips on the thermal element and then within a few milliseconds also trips off the magnetic element to ensure complete shut-down of the circuit.

The operation of the JTMP-2-1RLS4R-31615-400S breaker is simple but effective. It is designed with manual reset buttons that allow the breaker to be reset after an interruption. The reset buttons are protected by a lockable front cover, which helps to prevent unauthorized manipulation of the breaker. Once the breaker is manually reset, the thermal element is reactivated, allowing the breaker to remain in operation until another overload or short circuit is detected. If a second overload or short circuit is detected then the breaker will trip as before, requiring manual resetting.

The JTMP-2-1RLS4R-31615-400S breaker is suitable for a wide range of applications, from residential to commercial, small to large, from single to three phase systems. It is designed for use in motor control centers, panel boards, switchboards and other related applications. It is suitable for use in a variety of climates and environments, including those that are exposed to dust, moisture, and corrosive elements. The breaker is designed in accordance with IEC 60898-1, as well as UL 1077, making it suitable for use around the world.

The JTMP-2-1RLS4R-31615-400S breaker is an excellent example of the advancements in circuit breaker technology. With its efficient and reliable operation, it is designed to offer years of trouble-free service and protection for the electrical equipment it is protecting. It is easy to install and maintain, making it a popular choice among many electrical pros.
