They are used to protect batteries, generators, motors, and other electrical equipment from current overload and circuit shorts. Material: thermoplastic colour: Black Package Contents: 1 x circuit breaker panel 4 x screw 3 x switch wire(15CM) Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm. Circuit breaker rated current: 100A Note: The test data is based on a 25°C ambient environment. The duration is influenced by the ambient temperature. When the operating environment temperature is lower than 25°C, the duration will be extended. When the operating environment temperature is higher than 25°C, the duration will be shorter. Refer to the curve diagram for reference; Compliant with SAE J1428, J1625, J553 (200A), J1171, UL1500 (Ignition protection) Circuit breaker shell off current test data: Rated current 100A circuit breaker; at 25°C, at 1.35 times the rated current (135A), it trips within equal to or less than 1800 seconds; At 2 times the rated current (200A), it trips within approximately 60 seconds;
