The T21-2-15.0A-01-11AL-V is a two-pole, series trip hydraulic-magnetic circuit protector that combines power switching with reliable overcurrent protection. It is rated for 15.0A and features a slow time delay for operation on DC or 50/60Hz circuits, making it suitable for starting certain types of motors and most transformer or capacitor loads. This snap-acting protector ensures immediate opening of contacts, is trip-free to prevent being held on during an overload, and operates reliably in ambient temperatures from -40°C to +85°C. As a VDE and CCC approved device, it is commonly used in applications such as office appliances, electronic data processing, medical equipment, and business machines.
