EATON LD2600F LD35K I/O module

Product Detailed Description

• Function: The primary function of the LD2600F MCCB is to provide overcurrent protection for electrical circuits and equipment. It automatically interrupts the flow of electricity when an overcurrent condition (either an overload or a short circuit) occurs, preventing damage to downstream equipment, cables, and minimizing fire hazards.

• Protection Mechanism: It employs a combination of fixed thermal and fixed magnetic trip mechanisms:

• Fixed Thermal Trip: Responds to sustained overloads by heating a bimetallic strip, which eventually bends and trips the breaker. "Fixed" means the overload trip setting is not adjustable by the user.

• Fixed Magnetic Trip: Responds instantaneously to high short-circuit currents by generating a magnetic field that trips the breaker. "Fixed" means the short-circuit trip setting is not adjustable.

• Frame Only: The "Frame only" designation implies that the core mechanical and electrical structure, including the fixed trip unit, is provided. It typically requires lugs or other terminals to be added separately for wire connections.

• Series C: Part of Eaton's popular Series C line, known for its compact size, robust construction, and high performance.

• Application: Suitable for use as main circuit breakers, feeder circuit breakers, or branch circuit protection in various commercial, industrial, and utility applications.

• Certifications: UL 489 (Standard for Molded-Case Circuit Breakers, Molded-Case Switches and Circuit-Breaker Enclosures)

Product Advantages

• Reliable Circuit Protection: Eaton Series C MCCBs are known for their robust design and proven performance in protecting electrical systems from overloads and short circuits.

• High Interrupting Capacity: The 35 kAIC @ 480VAC rating provides significant fault current interruption capability, suitable for a wide range of industrial and commercial applications.

• Compact Design: Series C breakers offer a good balance of performance and space-saving design, allowing for higher density installations in panels and switchboards.

• Durable Construction: Built to withstand demanding industrial environments, ensuring long service life and reduced maintenance.

• Patented Contact Design: Features high-speed "blow-open" action, which contributes to superior performance during fault conditions by rapidly separating contacts to quench the arc.

• Reverse Feed Capable: L-frame circuit breakers with non-interchangeable trip units are generally suitable for reverse feed applications (where power is supplied to the load terminals).

• UL Listed: Ensures compliance with recognized safety standards for molded case circuit breakers.

Precautions

• Correct Selection: Always verify that the circuit breaker's amperage rating, voltage rating, and interrupting capacity are appropriate for the specific circuit and load it will protect. Over-sizing or under-sizing can lead to improper protection or nuisance trips.

• Proper Installation: Installation must be performed by qualified personnel in accordance with the National Electrical Code (NEC) or local electrical codes, and Eaton's installation instructions. Ensure proper torquing of terminal connections.

• Environmental Conditions: Install the breaker in an environment within its specified temperature and humidity ranges. Protect it from excessive dust, moisture, and corrosive atmospheres unless specifically rated for such conditions (e.g., in an appropriate enclosure).

• Wiring Compatibility: Ensure that the wire sizes used for connection are compatible with the breaker's terminals and the amperage rating. Use appropriate lugs or terminals for secure connections.

• Safety: Always de-energize the circuit before working on or around the circuit breaker. Follow Lockout/Tagout procedures. Never attempt to bypass or defeat the breaker's protective mechanisms.

• Maintenance: Although MCCBs are generally low-maintenance, periodic visual inspection for signs of damage or overheating is recommended.

• Accessory Compatibility: If using accessories (e.g., shunt trips, undervoltage releases, auxiliary contacts), ensure they are compatible with the LD2600F frame.
