## Summary description

Eti-Polam EB2S 250/3LA is a three-pole power circuit breaker rated at 250 A with 16 kA breaking capacity and adjustable thermal protection. Designed for industrial and commercial electrical panels, it provides overcurrent and short-circuit protection, configurable tripping via thermal regulation, and is suitable for motor feeders, distribution boards and protection of installations.

## Long description

Eti-Polam EB2S 250/3LA is a three-pole power circuit breaker rated for 250 A nominal current with a 16 kA rated short-circuit breaking capacity and adjustable thermal protection. Designed for industrial and commercial electrical distribution, this breaker provides overcurrent and short-circuit protection with configurable thermal tripping to match conductor and load characteristics. The compact three-pole design fits typical motor feeders, distribution boards and switchgear requiring reliable protection and selective tripping.
Advantages
The breaker combines a high 16 kA breaking capacity with adjustable thermal protection, enabling coordination with upstream and downstream devices and protection of conductors and motors. The three-pole configuration ensures simultaneous disconnection of all phases, reducing the risk of unbalanced faults. Its adjustable thermal element allows setting of tripping thresholds to accommodate varying load profiles while the robust mechanical construction ensures long-term operational stability in demanding environments.
Suitable for
 Protection of three-phase motor feeders and starters
 Incoming and distribution circuits in commercial and industrial panels
 Short-circuit and overcurrent protection in switchboards and control panels
 Applications requiring selective coordination with thermal adjustment
Key specifications
 Poles: three-pole design for three-phase systems
 Rated current: 250 A nominal
 Breaking capacity: 16 kA (short-circuit interruption capability)
 Protection types: overcurrent and short-circuit with adjustable thermal trip
 Thermal adjustment: configurable thermal tripping range for coordination with load and conductors
 Mounting: panel/switchboard mounting compatible with standard three-pole installations
How to use
Install the breaker in the distribution board or switchgear following local electrical codes and the equipment manufacturer's installation instructions. Connect the three-phase supply and load conductors to the corresponding terminals, ensuring secure tightness and correct torque values for terminals. Set the thermal adjustment according to conductor ampacity and motor starting characteristics to achieve proper tripping coordination. Verify correct operation by performing functional tests under de-energized conditions and by testing protection settings with qualified personnel before putting the circuit into service.
Usage recommendations
Regularly inspect terminal connections for tightness and signs of overheating, and verify thermal adjustment settings after significant load changes. Use coordinated upstream and downstream protection to maintain selectivity, and schedule periodic functional testing and maintenance in accordance with applicable standards to ensure continued reliable operation.
