It mounts into the drawout chassis — not bolted to a panel — so it slides in with the breaker cradle and connects through the racking mechanism. The part is a control accessory, not a standalone device: it trips the breaker when its control voltage is applied or removed, depending on the release function (opening coil). That dual-range AC/DC input is common on Schneider MX coils — it means the same part works in a panel with a 24 VDC control bus or a 24 VAC transformer supply. The threshold tripping voltage is 0.7 to 1.1 times the rated control voltage (Un), so the coil will reliably operate between about 17 V and 33 V for the DC variant. Holding power is 4.5 VA / 4.5 W — a standard control transformer or DC supply handles that without derating. Response time is 50 ms ±10% across all MTZ frames — MTZ1, MTZ2, and MTZ3. That means from the moment the trip signal hits the coil terminals to the breaker opening, you're looking at roughly 45-55 ms. For a line-down scenario, that's fast enough for most coordination schemes; if you need faster, you'd be looking at a different release type (e.g., a shunt trip with a different response curve).","metaTitle":"Schneider LV839233 MX Opening Voltage Release, 24 V AC/DC, M","metaDescription":"Schneider LV839233 MX opening voltage release for MasterPact MTZ drawout. 24 V AC 50/60 Hz / 24-30 V DC, 50 ms response.
