The Schurter Inc. 4420.0317 is a thermal magnetic circuit breaker designed for reliable circuit protection in industrial appliances and equipment. This 2-pole breaker features a manual ON/OFF actuation type and DIN rail mounting for easy installation.
Key electrical specifications include a rated current of 7A and a rated AC voltage of 480V (UL/CSA) or 240V (IEC). It also supports a DC voltage rating of 65V. The breaker offers a high short circuit capacity, with Icn ratings of 5 kA at 420V AC/65V DC (IEC, no fuse) and 5 kA at 480V AC (UL 508, no fuse). For UL 1077, the capacity is 10 kA with a fuse or 5 kA without a fuse at 480V AC, and 2 kA at 65V DC.
Environmental and mechanical features include an IP40 degree of protection from the front, a lifetime of 6000 switching cycles at 1x Ir, and resistance to vibration and shock. The operating ambient temperature range is -10°C to 55°C. It supports wire cross-sections from 1.5 to 25 mm² (16 to 4 AWG).
This circuit breaker is designed according to industry standards such as IEC 60934, UL508, and UL1077. It also includes a switched neutral function that closes with manual pole closure and opens automatically upon thermal magnetic tripping.
The breaker is rated for AC operation at 240 V (IEC) or 277 V (UL/CSA) and DC operation at 65 V.
