Why Choose the ABB E1B-A 1200 PR122/P-LI 1200A 3-Pole Withdrawable Air Circuit Breaker?
The ABB E1B-A 1200 PR122/P-LI, order code 1SDA057253R1, is a SACE Emax air circuit breaker moving part designed for dependable protection and switching in low-voltage power distribution systems. This E1B-A configuration combines a 1200 A rated current, three-pole construction and withdrawable execution with ABB's PR122/P electronic overcurrent protection technology.
The breaker is equipped with a PR122/P-LI R1200 electronic overcurrent release, providing long-time and instantaneous protection functions. Long-time protection helps safeguard circuits against sustained overload conditions, while instantaneous protection provides rapid operation during severe short-circuit faults, with an instantaneous setting identified at 18000 A for this configuration.
The withdrawable moving-part execution is designed for use with compatible ABB SACE Emax fixed switchgear equipment, supporting inspection, servicing and replacement without requiring the permanent power connections to form part of the moving breaker assembly. The unit is supplied with four auxiliary contacts and open/closed position indication for integration into switchgear monitoring and control systems.
