- Description
The Schneider Electric LV833670SP is an MN undervoltage release for MasterPact MTZ1, MTZ2 and MTZ3 air circuit breakers, wired for a 100/130 V AC / 100/130 V DC supply, that trips the breaker instantaneously if its control voltage falls below the set threshold — a safety function rather than a standard on/off command coil.

Selection Notes
LV833670SP trips the breaker the moment its 100/130 V AC / 100/130 V DC supply drops below 0.35-0.7 Un — size the upstream control circuit so a brief sag never crosses that threshold by accident. MTZ1 opens in 45 ms on an undervoltage event, roughly half the 95 ms response of the MTZ2/MTZ3 frames, which matters for coordination studies that assume a specific breaker-opening time on loss of control power.
