What Is A MCB Plug In Type ?
A MCB Plug In Type ZMB1 is a low-voltage power distribution protection component that integrates the “circuit protection function of a miniature circuit breaker” and a “plug-in mounting structure”. Its core feature is replacing the “screw terminal fixing” of traditional fixed circuit breakers with a “plug-in connection”. While providing overload and short-circuit protection for circuits, it significantly simplifies the installation, replacement, and maintenance processes.
- No complicated wiring disassembly required
- Low installation threshold
- Controlled power-off range
- Reduced electric shock risk
- Compatible with standardized bases
- Compact size, space-saving
- Stable contact
- Anti-misinsertion design
Due to its structural characteristics (current-carrying capacity is usually ≤ 63A, suitable for low-voltage low-power circuits), it is mainly used in low-voltage power distribution terminal scenarios, such as:
- Residential buildings: Branch circuits in living rooms, bedrooms, kitchens, etc. (e.g., socket circuits, lighting circuits);
- Small commercial premises: Branch power distribution in convenience stores and offices (e.g., cash register circuits, office equipment circuits);
- Industrial auxiliary circuits: Local protection for small workshop motors and control equipment (non-main power circuits).
