Product details

MX 2nd opening voltage release for MasterPact MTZ drawout

The Schneider Electric LV839242 is an MX 2nd opening voltage release — a control-mounted opening coil for MasterPact MTZ drawout circuit breakers. It operates on a 100-130 V AC 50/60 Hz or 100-130 V DC control circuit, with a tripping threshold of 0.7 to 1.1 times the nominal control voltage. The response time is 50 ms ±10% across the MTZ1, MTZ2, and MTZ3 frames.

Drawout mounting and panel integration

Mounting mode is drawout, meaning this coil installs into the MasterPact MTZ's control compartment and connects via the breaker's drawout cradle — no separate DIN-rail or panel footprint. The supply holding power is 4.5 VA / 4.5 W, which the control transformer must support continuously. Verify the control circuit voltage matches your site's supply: 100-130 V AC/DC, 50/60 Hz.

Frequently asked questions
