Product information

Description

The Legrand TX3 3-pole miniature circuit breaker is a robust electrical protection device engineered to ensure safety and reliability in demanding power distribution systems. With a rated current of 50 A and compatibility with voltages ranging from 240 V to 415 V, this circuit breaker is designed to handle significant electrical loads while maintaining consistent performance across standard 50-60 Hz frequencies.

Advantages

This device offers superior protection for electrical circuits by effectively managing high inrush currents, which are common in industrial and commercial environments. Its Type D tripping characteristic provides a delayed response to short-circuit currents, preventing nuisance tripping during the startup of heavy machinery or inductive loads. The compact 3-pole design allows for efficient space utilization within electrical distribution boards, while the high-quality construction ensures long-term operational stability and safety.

Suitable for

Industrial machinery and motor control centers
Commercial electrical distribution boards
Systems with high inrush current requirements
Three-phase electrical installations

This circuit breaker may not be suitable for residential lighting circuits or standard household appliances where a Type B or Type C characteristic is typically required to ensure faster tripping during minor faults. It is also not intended for use in environments exposed to moisture or dust without an appropriate protective enclosure, as the device itself is rated IP20.

Key specifications

Rated current: 50 A
Number of poles: 3
Tripping characteristic: Type D
Voltage range: 240 - 415 V
Frequency: 50 - 60 Hz
Protection rating: IP20
Dimensions: 88 mm (H) x 53.1 mm (W) x 77.8 mm (D)

The installation of this miniature circuit breaker should be performed by a qualified electrician in accordance with local electrical codes. The device is designed for mounting onto a standard DIN rail within a distribution board. Ensure that all wire connections are tightened to the manufacturer's specified torque settings to prevent overheating and ensure optimal electrical contact.

What to consider before purchase

Verify that the Type D characteristic matches the startup current requirements of your connected equipment.
Ensure the 50 A rating is appropriate for the cross-section of the cables being used.
Check the available space in your distribution board to accommodate the 3-pole width.
Confirm that the operating environment meets the IP20 protection requirements.

Always perform a thorough inspection of the electrical circuit and verify the load requirements before installing a 50 A Type D circuit breaker to ensure system compatibility and safety.
