Overview

Our Miniature Circuit Breaker (MCB) Isolator Switch is a professional low-voltage electrical protection device integrating circuit breaking and safe isolation functions. Manufactured in strict accordance with IEC 60898-1 and IEC 60947-3 international standards, this isolator switch features compact structure, stable performance and high safety coefficient. It can effectively protect electrical circuits from overload, short circuit and leakage faults, and achieve complete circuit isolation during equipment maintenance to ensure construction safety. Widely applicable to residential buildings, commercial buildings, industrial workshops, solar PV power systems and various low-voltage distribution boxes, it is the preferred safety protection component for modern electrical engineering.

Core Features & Advantages

  • Dual Functions of Protection & Isolation: Integrates overcurrent protection, short circuit protection and physical isolation switch functions. It can automatically cut off the power supply when circuit faults occur, and manually isolate the circuit to form a visible break for safe maintenance.
  • Wide Specification Coverage: Supports multiple pole types including 1P, 1P+N, 2P, 3P, 4P, with current range from 0.5A to 125A, covering household, commercial and industrial power demand, compatible with AC and DC power systems.
  • Premium Fireproof & Durable Material: Adopts high-strength flame-retardant PA66 shell, anti-aging, anti-breakdown, high temperature resistance and impact resistance. Internal pure copper conductive parts ensure low resistance, fast heat dissipation and stable electrical conductivity.
  • Standard DIN Rail Mounting: Designed with universal DIN rail installation structure, plug-and-play, easy and fast installation, no complex wiring required, saving construction time and cost.
  • High Breaking Capacity: Equipped with precise electromagnetic tripping system, fast fault response speed, reliable arc extinction performance, effectively avoid arc leakage and circuit burnout, greatly improve electrical system safety.
  • Long Service Life & Low Maintenance: Mechanical life up to 10,000 times, no frequent replacement required, reusable after fault reset, compared with traditional fuses, it has lower later maintenance cost and higher practicability.
  • Full Safety Certification: Comply with international IEC standards, pass strict quality tests, with stable performance in high and low temperature, humid and other harsh environments.

63a isolated miniature circuit breaker switches for household use

Application Scenarios

This MCB isolator switch is versatile and suitable for all low-voltage distribution occasions:
  • Residential Use: Household distribution boxes, lighting circuits, socket circuits, household electrical equipment overload protection.
  • Commercial Use: Office buildings, shopping malls, hotels, supermarket power distribution systems, commercial electrical equipment safety isolation.
  • New Energy System: Solar PV power generation systems, wind power auxiliary circuits, energy storage equipment DC circuit protection and isolation.
  • Industrial Use: Factory workshops, mechanical equipment, low-voltage control cabinets, industrial distribution box circuit protection.
  • Public Facilities: Schools, hospitals, subway, street lighting and other public power supply systems.

Product Advantages & Value

Different from ordinary miniature circuit breakers, our MCB isolator switch adds independent physical isolation function, which can form a visible disconnection point after power off, completely eliminate potential safety hazards of induced electricity and leakage, and provide double safety guarantee for equipment maintenance and circuit inspection. The optimized internal structure reduces power consumption and heat generation, effectively improving the stability of the power distribution system. With compact size, it saves installation space and is compatible with most mainstream distribution boxes on the market. High cost performance and long service life make it an ideal replacement for traditional circuit protection switches, widely recognized by global engineering contractors and electrical distributors.
