Description
Andeli SP 20A MCB – Product Overview
The Andeli SP 20A MCB is a single pole miniature circuit breaker designed to protect electrical circuits from overload and short circuit conditions. It is suitable for residential, commercial, and light-duty electrical installations where controlled and reliable circuit protection is required. The single pole configuration is designed to disconnect the live conductor during a fault, helping protect wiring systems and connected equipment.
This breaker is commonly installed in distribution boards to protect individual circuits such as lighting lines, socket outlets, or dedicated small appliances. It is intended for fixed low-voltage installations operating within standard 220–240V AC supply systems.
Andeli SP 20A MCB – Single Pole Protection
The Andeli SP 20A MCB features a single pole (SP) design, meaning it controls and isolates one conductor, typically the live line. This type of breaker is widely used in standard single-phase distribution systems for protecting branch circuits.
Single pole breakers are commonly selected for individual circuit protection where neutral isolation is handled separately within the distribution board. Proper breaker selection should always be based on the expected load and correct cable sizing.
Andeli SP 20A MCB – Thermal-Magnetic Operation
The breaker operates using a thermal-magnetic tripping mechanism. The thermal component responds to sustained overload conditions, helping prevent overheating of cables over time. The magnetic mechanism reacts quickly in the event of a short circuit, disconnecting the circuit almost instantly to reduce potential damage.
This combination allows the breaker to tolerate normal temporary current increases, such as those caused by equipment startup, while still providing protection against abnormal current flow.
Andeli SP 20A MCB – 20 Amp Current Rating
The 20A rating makes this MCB suitable for moderate-load circuits, depending on the installation method and cable size used. It is commonly applied in circuits supplying socket outlets, small power tools, kitchen appliances, or specific lighting arrangements that require slightly higher current capacity than standard lighting circuits.
Before installation, it is important to confirm that the 20A rating aligns with the intended circuit design and complies with local electrical regulations. Proper load calculation ensures safe and efficient system performance.
Andeli SP 20A MCB – Durable Construction
The breaker is enclosed in a heat-resistant insulating housing designed to contain internal arcs and provide protection against accidental contact with live components. The toggle switch clearly indicates ON and OFF positions, allowing easy manual operation.
In the event of a trip, the handle moves to indicate that the breaker has disconnected due to a fault. The compact modular design allows installation on standard DIN rails in most distribution boards, ensuring compatibility with common electrical panels.
Andeli SP 20A MCB – Suitable Applications
This MCB is appropriate for various fixed wiring applications, including:
Socket outlet circuits
Small appliance circuits
Lighting circuits with moderate load
Office and shop installations
Residential distribution boards
Light commercial electrical systems
It is designed for indoor installation within a suitable enclosure. The breaker should not be exposed directly to moisture, dust, or harsh environmental conditions without proper protection.
Andeli SP 20A MCB – Installation Guidelines
For reliable and safe performance:
Install on a compatible DIN rail inside an approved distribution board
Ensure the cable size supports the 20A rating
Tighten terminals securely to prevent overheating
Do not exceed recommended current limits
Follow applicable local electrical regulations
Have installation performed by a qualified electrician
Correct installation and periodic inspection support long-term electrical safety.
