Product details

It is classified as a voltage release type (opening coil) and draws a holding power of 4.5 W / 4.5 VA. The threshold tripping voltage spans 0.7 to 1.1 Un, and the response time is 50 ms ±10% across the MTZ1, MTZ2, and MTZ3 frames.

The LV839244 uses a drawout mounting mode, meaning it plugs into the breaker cradle rather than being hard-wired. This allows the opening coil to be swapped without removing the MasterPact MTZ from the switchgear — useful for retrofit or maintenance on drawout chassis.
