ELEKTROPLAST NEO OCB/B20/3P Miniature Circuit Breaker, 3-Pole, B-Curve, 20A, 6kA

The ELEKTROPLAST NEO OCB/B20/3P is a high-quality 3-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits. This device is designed to monitor current flow and automatically disconnect power in the event of an overload or short circuit, ensuring the safety of your electrical infrastructure. With its robust construction and precise tripping mechanism, it serves as a critical component in modern electrical distribution systems.

Advantages

This miniature circuit breaker offers exceptional reliability and durability for various electrical applications. Its B-curve tripping characteristic makes it particularly effective for protecting circuits with moderate inrush currents, such as lighting and general-purpose outlets. The 6kA breaking capacity ensures that the device can safely interrupt fault currents, providing peace of mind and preventing potential damage to connected equipment and wiring.

Suitable for

• Residential electrical distribution boards
• Commercial office lighting circuits
• General-purpose power outlets
• Small-scale industrial control panels

When it may not be suitable

This circuit breaker is not intended for use in circuits with high inrush currents, such as those powering large motors or heavy-duty transformers, where a C or D curve device would be more appropriate. It is also not suitable for applications requiring a higher breaking capacity than 6kA or for systems operating outside of the specified voltage and current ratings.

Key specifications

• Number of poles: 3
• Rated current: 20A
• Tripping characteristic: B-curve
• Breaking capacity: 6kA

How to use

The device is designed for standard DIN-rail mounting within an electrical distribution enclosure. Installation should be performed by a qualified electrician in accordance with local electrical regulations. Ensure that the supply power is disconnected before mounting the breaker. Secure the device onto the rail, connect the input supply cables to the top terminals, and connect the load cables to the bottom terminals, ensuring all connections are tightened to the manufacturer's specified torque.

What to consider before purchase

• Verify that the 20A rating matches the load requirements of your circuit
• Ensure the B-curve characteristic is compatible with your connected appliances
• Check that your distribution board has sufficient space for a 3-pole device
• Confirm that the 6kA breaking capacity meets the short-circuit current requirements of your installation

Usage recommendations

Regularly inspect the circuit breaker for signs of physical damage or overheating. It is recommended to perform a functional test of the tripping mechanism periodically to ensure continued operational safety.
