Onesto 2P 6kA MCB C-Curve DIN

• The Onesto Double Pole (2P) 6kA C-Curve Miniature Circuit Breaker (MCB) series offers reliable protection for two-conductor electrical circuits in residential, commercial, and light industrial applications.
• Designed to safeguard against overcurrents and short circuits, these MCBs feature a C-Curve tripping characteristic, making them ideal for general-purpose loads such as lighting, socket outlets, and small appliances requiring simultaneous disconnection of both live and neutral (or two phases).
• With a 6kA breaking capacity and compliance with IEC60898-1 standards, this range provides a dependable and safe solution across a wide array of current ratings from 1A to 100A.

Features

• Double Pole (2P) configuration for simultaneous protection of two conductors.
• Rated short-circuit breaking capacity (Icu & Ics): 6kA.
• C-Curve tripping characteristic: Suitable for general purpose, resistive, and moderately inductive loads.

• Dual Protection Mechanism: Thermo-magnetic trip unit offers precise protection against both sustained overloads (thermal) and immediate short circuits (magnetic).
• International Standard Compliance: Adherence to IEC60898-1 ensures recognized quality, safety, and performance.
• Wide Current Range: Extensive selection of current ratings allows for precise matching to various circuit requirements.
• Simplified Installation: Standard DIN rail compatibility ensures quick and convenient mounting in most distribution boards and enclosures.

In-Depth Technical Specifications

Ideal Use

• Single-phase circuits requiring switching of both live and neutral conductors for enhanced safety or regulatory compliance.
• Two-phase circuits in specific industrial or commercial applications.
• Protection of appliances and equipment like water heaters, air conditioning units (smaller capacity), and fixed machinery.
• General distribution circuits in residential, commercial, and light industrial environments where a 2P C-Curve MCB with 6kA breaking capacity is specified.
• Consumer units and sub-distribution boards.

Tips

• Application Check: Ensure a 2P MCB is required for your application (e.g., for complete isolation of line and neutral, or for two-phase loads).
• Correct Amperage: Select the MCB's current rating based on the circuit's conductor size and the load's normal operating current to ensure proper protection.
• Tripping Curve Consideration: The C-Curve is for general loads. For equipment with higher inrush currents (e.g., some motors), a D-Curve might be more suitable.
• Professional Installation: Installation should always be performed by a qualified electrician in accordance with local electrical codes and safety regulations.
• Secure Terminal Connections: Ensure all terminal connections are tightened to the manufacturer's specified torque values to prevent overheating and ensure a safe, reliable connection.
• Enclosure: While IP20 rated, install these MCBs within a suitable enclosure to provide adequate protection against environmental factors like dust and moisture, especially if a higher overall IP rating is needed.
