The LV847483 is a MasterPact M2c programmable contact designed for the MasterPact MTZ1 drawout circuit breaker platform. It functions as a safety logic controller element with 2 normally-open signal contacts, each rated 3 A at 250 V AC and 3 A at 30 V DC. The minimum load it reliably switches is 10 mA at 5 V DC, which matters when the contact is used in low-energy logic circuits — below that threshold, oxide films on the silver-alloy contacts may not break down, causing intermittent opens in PLC or safety-relay inputs.
The drawout mounting style means the contact block plugs into the MTZ1 cradle without disturbing the breaker's power connections. This is standard for MasterPact switchgear — the programmable contact is wired to the control wiring harness, and the entire assembly slides into the cassette. The 2 NO configuration gives two isolated signal paths, typically used for dual-channel safety circuits or separate status feedback to the PLC and a local annunciator.
