Product Description

The ABB Tmax T5N 630 is a series of high-performance Molded Case Circuit Breakers (MCCBs) within ABB’s SACE Tmax T family. Its primary function is to provide reliable protection, isolation, and control of electrical power distribution circuits in industrial, commercial, and utility applications.

• Type: Molded Case Circuit Breaker (MCCB).

• Frame Size: T5 (medium-high current frame).

• Rated Current (In): $630\,\text{A}$.

• Breaking Capacity Level: N (Normal).

• Protection Mechanism: It is available with both fixed Thermal-Magnetic (TMA) trip units for basic protection or, more commonly, advanced Electronic Trip Units (such as the PR221DS or Ekip series) for sophisticated, selective protection and communication.

Product Specifications

The specifications provided are typical for the T5N 630 frame size, which can be configured for 3-pole or 4-pole versions.

Electronic Trip Unit (The “Central Control Module” Feature)

When equipped with an Electronic Trip Unit (e.g., PR221DS or Ekip), the device gains significant control capabilities:

• L – Long Time Delay (Overload Protection): Adjustable rated current setting ($I_{1}$) and adjustable time delay ($t_{1}$).

• S – Short Time Delay (Short-Circuit Protection): Adjustable pickup setting ($I_{2}$) and time delay ($t_{2}$), crucial for selectivity (coordination).

• I – Instantaneous (High Short-Circuit Protection): Adjustable pickup setting ($I_{3}$).

• G – Ground Fault Protection (Optional on Ekip units): Adjustable pickup setting and time delay for earth fault protection.

• Communication: Advanced Ekip units offer communication protocols (Modbus, Profibus, etc.) for remote monitoring and control in a substation automation system.

Product Advantages

• High Breaking Capacity: The Tmax series is engineered to safely interrupt very high short-circuit currents, ensuring system integrity and reliability.

• Advanced Selectivity: With electronic trip units, the T5N 630 allows for precise setting of time-current curves (L, S, I), ensuring that only the breaker closest to the fault trips, minimizing system downtime.

• Field Versatility: It supports a wide range of accessories (auxiliary contacts, shunt trips, motor operators) and connection methods (front, rear, plug-in), making it adaptable to various panel designs.

• High Reliability & Durability: Designed for industrial environments, it features high electrical and mechanical endurance, reducing maintenance needs.

• Data and Connectivity (with Electronic Trip Unit): The ability to measure current, track diagnostics, and communicate status remotely makes it an integral part of modern smart electrical distribution systems.

Precautions

• Trip Unit Setting: The electronic trip unit must be set precisely according to the electrical network’s coordination study. Incorrect settings compromise selectivity and protection performance.

• Wiring/Torque: Use the specified cable size and ensure the terminals are tightened to the precise torque value provided by ABB to maintain optimal electrical contact and prevent overheating.

• Accessory Voltage: When adding accessories like shunt trips or undervoltage releases, ensure the control voltage of the accessory (e.g., $24\,\text{V DC}$, $110\,\text{V AC}$) matches the auxiliary supply.

• Maintenance: Although designed for high durability, periodic maintenance (visual inspection, checking trip function, and contact resistance) is necessary, especially after a short-circuit interruption.

• Application Environment: Ensure the breaker’s performance level (N) and breaking capacity ($I_{cu}$) are appropriate for the maximum expected fault current at the point of installation.

Product Applications

The Tmax T5N 630 is a foundational component used for primary and secondary protection in medium-to-large power distribution applications.

• Main Distribution Boards (MDBs): Used as the primary incoming breaker or as a large feeder breaker to protect distribution feeders.

• Feeder Protection: Protecting heavy-duty loads such as large motors, transformers, capacitor banks, or busbar feeders.

• Industrial Plants: Used in control panels and motor control centers (MCCs) to provide fault protection and isolation for major machinery.

• Commercial Buildings: Serving as branch circuit protection for large HVAC systems, elevators, and lighting panels.

• Renewable Energy: Used as a disconnect and protection device in the AC side of large solar (PV) inverters or wind turbine substations.
