50 amp single pole miniature circuit breaker (MCB) is a protective device used in electrical systems to protect circuits from damage caused by overcurrent or short circuits. This mini circuit breaker has protection functions of short circuit, overload, and circuit break, and can be mounted on a 35mm DIN rail.

Single Pole MCB Breaker Features

Rapid arc extinguishing system: This single pole mini circuit breaker eliminates line danger, can sense even small currents, and provides sensitive protection.
Thermosetting shell: 1 pole MCB breaker uses thermosetting plastic, which solidifies or has insoluble characteristics under heat or other conditions.
Sealed terminal: 50 amp miniature circuit breaker has a built-in sealed terminal, which is rust-proof and convenient, and meets certification standards.
Ergonomic handle: The handle is comfortable to operate, has high segmentation capacity, and is sensitive to action.

Tips: 50 amp 1 pole miniature circuit breaker applications

A 50 amp 1 pole miniature circuit breaker (MCB) is commonly used in residential, commercial, and light industrial applications to protect electrical circuits from overloads and short circuits. In residential settings, it’s typically used for high-power appliances like electric water heaters, ovens, and air conditioning units. In commercial buildings, it can protect lighting circuits, small machinery, and HVAC systems. Light industrial applications include safeguarding equipment like small motors and specialized tools.

The single pole design means the mini MCB protects one live wire, making it suitable for 120V circuits in North America or single-phase circuits in other regions. Its compact size allows easy installation in standard electrical panels, saving space while ensuring reliable protection. Additionally, the quick trip mechanism prevents damage to connected devices and reduces fire risks. Always ensure compatibility with the circuit’s voltage and load requirements, and consult local electrical codes or a qualified electrician before installation.
