Earth-Leakage Circuit Breaker (Thermal Magnetic)
ZLM30L series earth-leakage circuit breaker is a new type of circuit breaker developed by us. Basing on Mitsubishi PSS series, our earth-leakage circuit breaker is widely used in electricity distribution networks for distributing energy and protecting the electrical circuit and power equipment from damage caused by overload, short circuit or under-voltage.

Features of Earth-Leakage Circuit Breaker (Thermal Magnetic)
1. According to its rated short-circuit breaking capacity, our earth-leakage circuit breaker falls into three types---Compact type (C), Standard type (S) and High capability type (H);
2. The three types of ELCB possess the same overall dimension in the same frame current;
3. In order to make operation easier, its overall dimension is classified into five specifications;
4. In order to make operation easier for users, the external dimensions of MCCB, ELCB, Thermal Magnetic Adjustable breaker and Electronic Adjustable breaker are uniformly divided into five kinds of sizes(adjustable breaker are divided into 4 kinds of sizes),under same frame size, the external dimensions of MCCB,ELCB, Thermal Magnetic Adjustable breaker and Electronic Adjustable breaker are completely same.
5. With the rated current 30A-800A, the panel size is of a standard and reasonable design;
6. Our earth-leakage circuit breaker is easy to install and safe to operate.
7. It can be installed vertically or horizontally.
8. It is in conformity with IEC60947-2 and GB14048.2 standards.

Working and Mounting Conditions
1. The maximum altitude is above 2000m.
2. The ambient medium temperature should be within -5℃ to +40℃ (+45℃ for shipping product).
3. This earth-leakage circuit breaker is resistant to moisture, salt fog, oil fog, nuclear radiation, mildew, and more.
4. The maximum tilt angle is 22.5°.
5. It works reliably even when the product is subjected to vibration from ships, earthquakes (4g), etc.
