General Electric | TR21540 | Circuit Breaker | 4-Pole | 240V

Meet the General Electric TR21540 4-Pole 240V Circuit Breaker—built for dependable overload protection in demanding electrical systems. Designed for maintenance, retrofit, and replacement in GE panels, this unit delivers precise fit and trusted performance when you need to protect 3-phase equipment and complex electrical loads.

Why the TR21540 stands out

Designed as a true 4-pole solution, this GE circuit breaker provides simultaneous disconnection across all poles, a critical safety feature for 3-phase, 4-wire systems. The 240V rating ensures reliable protection for high-demand circuits such as motors, compressors, and controlled equipment, helping to prevent damage from overcurrent events. By choosing a part-numbered unit—TR21540—you align with GE’s proven engineering standards, reducing uncertainty during replacement or retrofit projects.

Key specifications

• Poles: 4-Pole
• Voltage: 240V
• Part number: TR21540
• Application: Suitable for maintenance, retrofit, and replacement in compatible GE panels
• Compatibility note: Confirm fit and ratings before ordering; the TR21540 part number is the best reference for compatibility

Ideal use cases

Perfect for commercial or industrial environments where 3-phase equipment requires reliable, simultaneous pole disconnection. Common scenarios include:

• Motor control circuits and three-phase drives in manufacturing or processing facilities
• HVAC systems and large compressors that run on 240V multi-pole configurations
• Panel retrofits or replacements where exact GE specification needs to be maintained

How it solves real problems

Uncertain compatibility and mismatched replacements can lead to improper protection and nuisance trips. The TR21540 is a purpose-built, GE-branded solution that minimizes mismatch risk, ensuring your protection scheme remains intact after a service event. Its four-pole design reduces the number of components you need to manage and simplifies maintenance workflows in panels designed for 4-wire, 240V systems.

Practical tips for installation and care

• Before purchasing, verify panel compatibility by referring to the panel’s labeling and the TR21540 part number as the reference point for fit.
• Keep a spare TR21540 on hand for proactive maintenance in facilities with high uptime requirements.
• Use the 240V rating as a guide for the expected load characteristics—match to the equipment’s operating voltage to ensure proper protection level and trip characteristics.
