The M&M C20 Miniature Circuit Breaker (MCB) is designed to provide dependable protection against overloads and short circuits. Built with high-quality materials and engineered according to IEC/EN 60898-1 standards, it ensures safety, durability, and stable performance in residential, commercial, and industrial applications.

Available in Single Pole (1P), Double Pole (2P), Triple Pole (3P), and Four Pole (4P) variants, the M&M C20 series offers versatile protection solutions for different power setups.

Single Pole (1P) – Basic and Effective Protection

The 1P MCB protects one live (phase) wire in a circuit. It is commonly used in:

Lighting and socket circuits in homes and offices
Small appliances and low-load equipment
Individual line protection in distribution boards

👉 Why choose 1P?

Compact and economical
Protects against overload and short circuit on a single line
Ideal for residential and small-scale use

Double Pole (2P) – Safe for Single-Phase Systems

The 2P MCB protects both phase and neutral conductors at the same time, ensuring higher safety in single-phase systems.

Applications:

Single-phase distribution boards
Home and office wiring systems requiring neutral disconnection
Small machines and sensitive appliances

👉 Why choose 2P?

Disconnects both live and neutral during fault
Extra safety for sensitive loads
Reduces the risk of electric shocks

Triple Pole (3P) – Protection for Three-Phase Loads

The 3P MCB is designed for three-phase power systems, commonly used in industrial and commercial setups.

Applications:

Three-phase motors and equipment
Industrial distribution panels
Commercial buildings with heavy loads

👉 Why choose 3P?

Simultaneous protection of all three phases
Prevents equipment damage due to phase faults
Essential for stable operation of industrial systems

Four Pole (4P) – Complete Safety with Neutral Disconnection

The 4P MCB extends the protection of 3P breakers by also covering the neutral conductor, ensuring maximum safety.

Applications:

Three-phase four-wire systems
Sensitive installations like labs, data centers, and IT setups
Industrial panels requiring neutral isolation

👉 Why choose 4P?

Full isolation of all phases and neutral
Prevents leakage and neutral faults
Provides the highest level of safety in demanding environments
