100A Isolator Switch ZMG1-125

The ZMG1-125 miniature isolating switch is suitable for the power distribution and control circuits with an alternating current of 50Hz, a rated current of 125A or less, and a rated voltage of up to 400V. It mainly serves as the main switch in the terminal combination electrical appliance, and can also be used to infrequently control various small-power electrical appliances and lighting. It is widely applied in industrial and mining enterprises, high-rise buildings, commercial places, households and other locations.
Compliance standards: GB/T 14048.3, IEC 60947-3.

Miniature Isolating Switches (MIS) are core devices in low-voltage power distribution systems, used for circuit isolation and ensuring maintenance safety. Their advantages revolve around three core aspects: safe isolation, convenient operation, and wide application adaptability.

1. Core Advantage: Physical Isolation to Eliminate Maintenance Safety Hazards

2. Operational Advantage: Simple Structure and Clear On/Off Status

3. Adaptability Advantage: Compact Size and Flexible Installation

4. Performance Advantage: Strong Withstanding Capacity and Stable Operation

5. Cost Advantage: High Cost-Effectiveness and Low Maintenance Costs

   Miniature isolating switches are not used for fault protection (such as overload and short circuit). Instead, through physical isolation + clear status indication + convenient operation, they address the core needs of “maintenance safety” and “circuit breaking control”. Especially in household power distribution, small commercial premises, and industrial auxiliary circuits, they are “essential devices” that ensure personnel safety and simplify operation and maintenance. They form a complementary “protection + isolation” combination with miniature circuit breakers, jointly building a safe system for low-voltage power distribution.

   Miniature isolating switches are suitable for multiple scenarios, including homes and residential buildings, small commercial and public spaces, household photovoltaic system isolation, backup power switching isolation, and medical auxiliary equipment isolation.
