Product details

The LV846182 is a MasterPact MTZ2 fixed circuit breaker from Schneider Electric's MasterPacT range, built for power distribution protection in industrial and commercial switchboards. The 4-pole design with neutral on the left is common for three-phase + N distribution. Selectivity category B means it coordinates with downstream breakers to isolate only the faulted branch — a key requirement for maintaining uptime on a critical bus.

Breaking capacity and what that means for your panel

The H2V performance level delivers 100 kA Ics at 415 V AC and 440 V AC.

Integration and mounting constraints

Fixed mounting on rails or a base plate. The 537 mm width, 352 mm height, and 300 mm depth — plus the 115 mm connection pitch — determine the panel cutout and busbar layout. Front or rear connections on both the line and load sides give flexibility for cable entry direction. IP30 means no protection against water ingress; install inside a switchboard enclosure rated for the environment. Derate above 2000 m altitude.

Suitability for isolation per EN/IEC 60947-2 means it provides a visible break and meets the safety requirements for disconnecting a circuit.

Frequently asked questions

How do I get current pricing and availability for LV846182?

The LV846182 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm quote.

What is the closest alternative to LV846182 in the MasterPact family?

Within the MasterPact MTZ2 range, the closest alternative would be a different performance level (e.g., H1 or H3) or a different rated current. The LV846182 is the 1250 A, H2V, 4P fixed version. If your fault current requirement is lower, an H1 variant (65 kA) may save cost; if higher, an H3 (150 kA) exists. All share the same frame, mounting, and connection pitch.

What compliance documentation does LV846182 come with?

The breaker is designed to EN/IEC 60947-1, EN/IEC 60947-2, and EN/IEC 60947-2 Annex H. It carries a suitability-for-isolation marking per EN/IEC 60947-2. For RoHS, REACH, and UL documentation, the manufacturer's product compliance page or a request through the distributor is the standard path.
