Review MURRAY Duplex Type Mh t Circuit Breaker 120 Vac 30 Ka

The Murray MP3030 Duplex MH-T Circuit Breaker is a versatile and reliable electrical safety device designed for use with 120 Volt AC power systems. This circuit breaker features a duplex design, which allows for the installation of two circuit breakers in a single housing, making it an ideal solution for applications where space is limited.

The MP3030 circuit breaker is rated for a current interruption capacity of 30 Amperes and a thermal trip rating of 10 Kalgoras. This means that it can safely interrupt up to 30 Amperes of current to prevent overloads or short circuits, and its thermal trip function will automatically disconnect the power if the temperature of the circuit exceeds safe levels.

The MH-T designation of this circuit breaker signifies that it is a molded case circuit breaker with a thermal magnetic trip unit. This type of circuit breaker provides fast and accurate tripping action by combining thermal and magnetic trip elements. The thermal element responds to the temperature rise in the circuit, while the magnetic element trips when the current exceeds a predetermined level.

The Murray MP3030 circuit breaker also features a convenient slide-out handle design, which allows for easy operation and testing. The handle can be slid out to the "OFF" position to disconnect power to the circuit, and it can be slid back to the "ON" position to restore power once the issue has been resolved. Additionally, the circuit breaker comes with a test button, which can be used to simulate a short circuit condition and verify that the breaker is functioning correctly.

Overall, the Murray MP3030 Duplex MH-T Circuit Breaker is a high-quality and reliable electrical safety device that is ideal for use in residential, commercial, and industrial applications where 120 Volt AC power is being used. Its duplex design, fast tripping action, and slide-out handle make it a convenient and practical solution for a wide range of electrical wiring applications.
