TMAX T5N630 ABB Bailey

TMAX T5N630 ABB Bailey Analog Output Modules

Product  Description：

• • • • The ABB SACE Tmax T5N 630 is a high-performance Moulded Case Circuit Breaker (MCCB) designed for reliable protection and isolation in low-voltage electrical distribution systems. It is part of the extensive ABB SACE Tmax T series of circuit breakers.

        Product Specifications

        • Product Type: Moulded Case Circuit Breaker (MCCB)

        • Frame Size/Series: Tmax T5

        • Short-Circuit Performance Level: N (Standard Breaking Capacity)

        • Rated Uninterrupted Current ($\text{I}_\text{u}$): $630 \text{ A}$ (Amps)

        • Number of Poles: 3-pole (suitable for three-phase AC systems)

        • Mounting Style: Fixed installation (F)

        • Connection Type: Front terminals (F)

        • Rated Operational Voltage ($\text{U}_\text{e}$): Up to $690 \text{ V AC}$

        • Rated Ultimate Short-Circuit Breaking Capacity ($\text{I}_\text{cu}$): $36 \text{ kA}$ at $380/415 \text{ V AC}$ (This value determines the maximum fault current the breaker can safely interrupt)

        • Rated Service Short-Circuit Breaking Capacity ($\text{I}_\text{cs}$): $36 \text{ kA}$ at $380/415 \text{ V AC}$ (Often 100% of $\text{I}_\text{cu}$ for this series, ensuring reliable operation after interruption)

        • Release Type: Electronic Release (EL), typically a solid-state trip unit like the PR221DS-LS/I.

        • Protection Functions: The electronic release offers adjustable protection settings for:

          • L (Long Time): Overload protection

          • S (Short Time): Short-circuit protection with a time delay

          • I (Instantaneous): Instantaneous short-circuit protection

        • Standards: Compliant with IEC 60947-2 international standards.

        Product Advantages

        • High Performance and Safety: The Tmax series features a high-speed electric arc interruption system, which minimizes the specific let-through energy ($\text{I}^2\text{t}$), significantly reducing thermal and mechanical stress on downstream equipment during a short-circuit fault.

        • Selectivity and Coordination: The optional electronic trip units, such as the PR221DS, allow for precise setting of the protection curves, enabling superior selectivity with other protective devices in the network to ensure that only the faulty section of the system is isolated.

        • Compact Design: Despite its high-current rating and breaking capacity, the T5 breaker maintains a compact size, allowing for space-efficient installation in switchgear and control panels.

        • Flexible Protection: The electronic release provides highly accurate and adjustable protection functions (L, S, I), offering greater flexibility compared to fixed thermal-magnetic releases for matching specific load characteristics.

        • Wide Range of Accessories: The Tmax family supports a comprehensive array of internal and external accessories, including auxiliary contacts, shunt trips, undervoltage releases, and motor operators, for enhanced control and monitoring capabilities.

        Important Considerations (Precautions)

        • Qualified Personnel: Installation, wiring, and maintenance must only be performed by qualified, authorized electrical personnel.

        • Power Disconnection: Always ensure the circuit is de-energized and verified as dead before any installation, wiring, or service work is performed on the MCCB to prevent electric shock.

        • Torque Settings: Terminal screws must be tightened to the manufacturer's specified torque values. Insufficient torque can lead to poor electrical contact, overheating, and eventual failure, while excessive torque can damage the terminals.

        • Correct Calibration: The settings on the electronic trip unit (e.g., L, S, I settings) must be correctly calculated and set according to the application's load requirements and upstream/downstream device coordination to ensure proper protection.

        • Environmental Conditions: The breaker should be installed in an appropriate electrical enclosure that provides adequate protection against dust, moisture, and extreme temperatures to ensure its rated performance and longevity.

        Product Applications

        The ABB Tmax T5N 630 MCCB is designed for demanding power distribution and industrial applications.

        • Main and Sub-Distribution Boards: Used as the primary protective device for incoming power feeders and outgoing lines in commercial buildings, factories, and industrial facilities.

        • Industrial Machinery: Providing reliable protection for high-current circuits supplying large industrial loads, such as motor control centers, large pumps, compressors, and heating systems.

        • Transformer Protection: Used to protect the secondary side of distribution transformers from overloads and short circuits.

        • Generator Sets: Installed in generator power output circuits for protection and isolation.

        • Infrastructure: Utilized in critical infrastructure like data centers, hospitals, and transportation systems where high reliability and selective fault isolation are paramount.
