Product details

The LV846321 is a Schneider Electric MasterPact MTZ2 25 HH switch-disconnector rated for 2500 A at 440 V AC, 4 poles, in a drawout chassis mount.

Rated operational current is 2500 A AC at 440 V, with utilisation categories AC-23A and AC-3 covering motor switching and mixed resistive-inductive loads. The short-time withstand rating is 75 kA for 3 seconds (or 100 kA for 1 second), which coordinates with downstream protection devices during a delayed trip. Mechanical durability is 15,000 cycles with periodic preventive maintenance; electrical durability is 5,000 cycles at 440 V under AC-23A duty.

This is a drawout switch-disconnector mounted on a chassis, with a 115 mm connection pitch. Panel cutout dimensions are 556 mm wide by 439 mm high by 403 mm deep.

Frequently asked questions

What is the breaking capacity of LV846321?

The LV846321 has a rated breaking capacity (Icu) of 100 kA at both 220/415 V AC and 440 V AC, 50/60 Hz, per EN/IEC 60947-2. The service breaking capacity (Ics) is also 100 kA at those voltages.

What standards does the LV846321 comply with?

The LV846321 complies with EN/IEC 60947-3 for switch-disconnectors and EN/IEC 60947-2 for circuit-breaker performance. It is suitable for isolation per EN/IEC 60947-3 and carries a pollution degree 3 rating per EN/IEC 60947-4-1.
