This E-T-A 1620-3H-10A is a single-pole, thermal miniaturised circuit breaker (Mini-CBE) specifically engineered for automotive electrical system protection. It conforms to ISO 8820-3, Type F fuse block standards, making it a direct replacement for compatible fuse types.
The circuit breaker offers a 10A current rating and a maximum voltage rating of 29V DC, suitable for both 12V and 24V systems. It meets SAE J553 requirements and provides automatic reset functionality for 12V DC systems. The open circuit version ensures contacts remain open until the load is removed, with a reset period of less than 35 seconds.
Designed for installation in potentially inaccessible locations, this thermal circuit breaker operates within an ambient temperature range of -40°C to +85°C. Its robust construction is tested for vibration, shock, corrosion, and humidity resistance according to IEC standards, ensuring reliability in demanding automotive environments. The device has a service short-circuit breaking capacity of 300 operations at 2x IN and an ultimate short-circuit breaking capacity of up to 2000A.
Key technical data includes a typical voltage drop of less than 150mV at rated current. The operating area offers IP40 protection, while the terminal area is IP00. Its compact size and lightweight design (approx. 3g) facilitate integration into various automotive fuse block designs.
