Power switch LZM3, 3-pole Ir=315-630A LZMN3-AE630-I 111969

Power switch for demanding applications

The LZM3 power switch is a reliable solution for protecting electrical installations, both in construction and industry. The three-pole design with an overload release setting range of 315-630A provides flexibility and adaptation to different loads. The rated continuous current of 630A guarantees stable operation even with high power consumption.

Functionality and safety in one device

The LZM3 switch is characterized by a high short-circuit breaking capacity of 50kA at 400V, which ensures effective protection against the effects of short circuits. The lack of an integrated undervoltage release and earth fault protection allows for flexible adaptation to the specific requirements of the installation, and the optional motor drive expands the possibilities of remote control. The location of the main circuit connections on the front side facilitates installation and access to connections.

Wide compatibility and accessories

LZM3 switches are compatible with a wide range of additional Eaton accessories, such as remote drives, releases, and auxiliary contacts – allowing the device to be adapted to individual project needs. The possibility of using direct or door-type rotary drives and mechanical locking of manual drives increases functionality and safety. It is also worth mentioning the possibility of using releases to protect motors and generators, as well as NZMH versions with a high short-circuit capacity of 100kA. Compliance of electrical parameters to a temperature of 50°C ensures stable operation in various environmental conditions.
