The D52S30A is a 30 Amp welding grade circuit breaker manufactured by ABB. This device is a cost-effective solution for applications requiring reliable fault protection and high reliability. The D52S30A is designed for use in industrial and commercial applications including motor control centers, distribution boards, and motor control panels. The device is also capable of providing overload and short-circuit protection to prevent premature failure of the connected equipment.

The D52S30A features ABB’s reliable Minigrip technology which provides maximum contact stability and withstands thermal overloads better than other circuit breakers. In addition, the device is UL-approved and features an adjustable trip rating of up to 30 amps. The D52S30A also has a wide range of accessories including an adjustable shut-off switch, terminal block, and trip indicator.

The D52S30A is designed to be used with a welding grade (0.081–0.080) filer media. This is important because the lower the welding grade filer media the better the weld and the less chance of a fault occurring in the welding process. The D52S30A is designed to be connected to either single-phase or three-phase systems. The device features a push-to-test mechanism that ensures the breaker will reset correctly after the test has been conducted.

To understand the working principle of the D52S30A, it is important to know that it is a thermal-magnetic circuit breaker. This means that when a certain current level is exceeded, the trip coil in the device will heat up. This causes the trip indicator to open so that the high current is cut off from the circuit. This will prevent any further damage occurring to the connected equipment.

The D52S30A circuit breaker is ideal for motor control centers, distribution boards, and motor control panels. Thanks to its low cost and high reliability, the device is also suitable for use in machine applications and for providing overload and short-circuit protection. The adjustable trip rating of up to 30 amps ensures protection against high current loads, and the UL-approved Minigrip technology greatly helps to prevent premature failure of the connected equipment.
