The Schurter Inc. 4420.0237 is a thermal-magnetic circuit breaker designed for equipment protection. It offers high short circuit performance and is available in AC and DC configurations within the same frame size.
This 2-pole breaker has a rated current of 5A and a rated voltage of 480V AC (UL/CSA) or 240V AC (IEC). It also supports a DC voltage rating of 65V. The breaker is designed for DIN-rail mounting and features a manual ON/OFF actuation type with a positively trip-free mechanism.
Key electrical specifications include a conditional short circuit capacity of 5 kA at 480V AC (no fuse) and 2 kA at 65V DC (no fuse). It has a lifetime of 6000 switching cycles at 1x Ir and an insulation resistance greater than 5 MΩ at 250/440 VAC. The degree of protection from the front side is IP40.
Applications for this circuit breaker include industrial appliances. It supports wire cross-sections from 1.5 to 25 mm² (16 to 4 AWG). The switched neutral function closes with manual closure of the poles and opens automatically with thermal magnetic tripping.
