It mounts onto the breaker body. ## What the voltage rating means for fit The dual AC/DC coil covers standard European control voltages: 230 V line-to-neutral on a 400 V three-phase system, or a 220 V DC control bus from a rectified supply. The dropout voltage is typically 70–35% of rated, so on a 230 V AC line the release will trip somewhere between 161 V and 80 V — early enough to drop the load before contactor chattering starts. Verify your control transformer secondary matches the 220...240 V AC band; the 220...250 V DC band covers most industrial battery-backed DC buses. ## Compliance documentation The 3RV1982-1AF0 carries a Substance Prohibitance date of 05/01/2012. As a SIRIUS accessory, it falls under Siemens' standard declaration of conformity for low-voltage switchgear and controlgear assemblies.","metaTitle":"Siemens 3RV1982-1AF0 SIRIUS Undervoltage Release, 220-240V A","metaDescription":"Siemens 3RV1982-1AF0 SIRIUS undervoltage release for 3RV1.6/7/8. 220-240V AC, 220-250V DC.
