Why Choose the ABB E1.2C 1250 Ekip Touch LI 4p WMP Air Circuit Breaker?
The ABB E1.2C 1250 Ekip Touch LI 4p WMP, order code 1SDA072814R1, is a high-performance four-pole withdrawable air circuit breaker moving part designed for protection and switching in low-voltage power distribution systems. Part of the ABB SACE Emax 2 E1.2 series, it combines a 1250 A rated current with an Ekip Touch LI electronic trip unit for advanced overload and instantaneous short-circuit protection.
The Ekip Touch LI solid-state electronic release provides long-time overload and instantaneous short-circuit protection. Protection thresholds can be configured through the touch-sensitive display, with overload protection adjustable from 0.4–1 × In and instantaneous protection from 1.5–15 × In, supporting precise coordination with the electrical distribution system.
The E1.2C performance level provides an ultimate short-circuit breaking capacity of 50 kA at 400/415 V AC and 42 kA at 690 V AC, with a rated short-time withstand current of 42 kA for 1 s. Its withdrawable moving-part construction enables convenient servicing and replacement when installed with the corresponding ABB Emax 2 fixed chassis.
Key Advantages
- 1250 A rated current for demanding low-voltage power distribution.
