Breaking capacity reaches 100 kA at 240 V AC, 50 kA at 400 V, 10 kA at 500 V, and 4 kA at 690 V. At the common 400 V line, 50 kA covers most industrial service-entrance fault levels without requiring an upstream current-limiting fuse — a real panel-space saver.
Terminals accept 1 to 2.5 mm² solid or stranded (two wires per clamp) and 2.5 to 6 mm² (two wires).
Shock-rated to 25g for 11 ms. RoHS compliant per the substance prohibition date of 01.05.2012.
The 3RV6021-4DA10 is a peer in the SIRIUS family with a similar motor-protection role, but verify your specific current and breaking-capacity requirements — the ratings differ. We can source both and confirm fit against your BOM.
RoHS compliant per the substance prohibition date of 01.05.2012. Standard documentation includes CE, UL, and CSA certifications — available on request with the RFQ.
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time — no minimum order quantity restrictions.
