The Schurter Inc. 4420.0173 is a thermal-magnetic circuit breaker designed for equipment protection. This 1-pole breaker offers high short-circuit performance and is suitable for AC and DC applications within the same frame size.
Key electrical specifications include a 4A current rating and a 277V AC voltage rating. The breaker operates with a thermal-magnetic tripping mechanism and features a positively trip-free design. It is designed for DIN rail mounting and accepts wire cross-sections from 1.5 to 25 mm² (16 to 4 AWG).
Applications for this circuit breaker include industrial appliances. The device offers a degree of protection from the front side of IP40 and has a lifetime of 6000 switching cycles at 1x Ir. It meets various approval standards including CSA and UL.
Note: The datasheet references part number AS168XAC1 and lists different current and voltage ratings than those specified for the 4420.0173 part number. This may indicate a content mismatch or that the datasheet covers a broader series.
