This Schurter Inc. 4400.0021 is a thermal circuit breaker with a 1.5A current rating and a voltage rating of 240 VAC / 48 VDC. It is designed for panel mounting and features quick connect terminals for easy installation.
The breaker offers a conditional short circuit capacity of 2 kA and a short circuit capacity (Icn) of 8 x In (for In < 6.5A) or 96 A (for In ≥ 6.5A). It operates within a temperature range of -5 °C to 60 °C and has an ingress protection rating of IP40 on the front side.
Key features include a compact design, positively trip-free release, and different mounting possibilities. The actuation type is push-to-reset, and it has an endurance of typically 500 switching cycles at 2 x Ir. Applications include power tools, household equipment, power supplies and chargers, and industrial appliances.
The circuit breaker is rated for 240 VAC and 48 VDC.
The allowable operating temperature is -5°C to 60°C.
It is panel mounted with quick connect terminals.
