The Schurter 4420.0512 is a thermal-magnetic circuit breaker designed for equipment protection. It offers high short circuit performance and is available in the same frame size for both AC and DC applications.
Key electrical specifications include a rated current of 10A and a voltage rating of 277V AC (UL/CSA) and 65V DC. The breaker has a conditional short circuit capacity of up to 10 kA (UL 1077) and 5 kA (IEC 60934). It is designed for 6000 switching cycles at 1x Ir.
This circuit breaker features manual ON/OFF actuation and a positively trip-free mechanism. It is suitable for wire cross-sections from 1.5 to 25 mm² (16 to 4 AWG). The degree of protection from the front side is IP40.
Mounting is achieved via DIN rail, making it suitable for industrial appliances and control panels. The switched neutral function ensures that the neutral closes with manual pole closure and opens automatically with thermal magnetic tripping.
