3D20UM

Circuit breakers are an essential part of the electrical industry and have a wide variety of applications. One such product is the 3D20UM, which is an advanced molded case circuit breaker (MCCB) that offers superior protection, exceptional reliability, high performance, ease of installation and maintenance. This article will take a look at the 3D20UM application field and working principle.

The 3D20UM is designed for use in panel systems and distribution boards that are used in residential, commercial, and industrial applications. It has a current rating of up to 125 A, and can be used to protect both DC and AC electrical systems up to 600V. The product is engineered to meet both industry and customer requirements, and can be used in marine and explosion proof environments.

The 3D20UM is designed for safety and reliability. It is designed to trip when an abnormal current or voltage is detected, to protect downstream components and prevent electrical fires. The trip unit monitors both line and load current and has built-in self-test and thermal overload protection capabilities. It is also designed to prevent short-circuiting and reverse current.

In terms of installation and maintenance, the 3D20UM has several innovative features that make it easier to use. It has spring-loaded terminals, so installation only requires a simple alignment and tightening of the terminal screws. The operating knob has also been specifically designed for ease of use, with a one-finger, one-action design. The product also has a load side test function that can be used to quickly test the breaker without having to de-energize the circuit.

The 3D20UM is an advanced and reliable circuit breaker that offers superior protection for operational safety and reliability. It has a wide range of applications, from residential and light commercial installations to industrial and hazardous areas. The product is designed for easy installation and maintenance, and is engineered to meet the highest industry standards.
