Why Choose the ABB 1SDA072726R1 Emax 2 E1.2B 800 Air Circuit Breaker?
The ABB 1SDA072726R1 is a high-performance SACE Emax 2 E1.2B air circuit breaker designed for protection, switching and control in low-voltage electrical distribution systems. Configured as the E1.2B 800 Ekip Touch LSIG 4p WMP, this four-pole withdrawable moving part combines a 800 A rated uninterrupted current with ABB's advanced Ekip Touch LSIG solid-state electronic protection release.
The Ekip Touch LSIG release provides comprehensive long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. Its adjustable electronic protection functions support coordinated protection and selectivity within distribution networks, while integrated ground-fault protection provides an additional layer of protection for suitable electrical systems.
The E1.2B performance level provides a rated ultimate short-circuit breaking capacity of 42 kA at 400 V AC and is suitable for systems with rated voltage up to 690 V AC. Its withdrawable moving-part construction, four-pole configuration and fitted auxiliary contacts make it a versatile solution for switchboards requiring advanced protection and convenient maintenance access.

Comprehensive Protection for Low-Voltage Power Distribution
The ABB SACE Emax 2 E1.2B provides switching and overcurrent protection for low-voltage electrical distribution systems. Its electronic trip unit monitors current conditions and initiates circuit interruption when configured protection thresholds are exceeded, helping protect conductors, switchgear and connected equipment against overload, short-circuit and ground-fault conditions.
The Ekip Touch LSIG release combines four key protection functions within one electronic protection unit: long-time overload protection, short-time short-circuit protection, instantaneous short-circuit protection and ground-fault protection. Combined with adjustable protection thresholds and withdrawable construction, the ABB 1SDA072726R1 provides a flexible solution for distribution systems requiring comprehensive protection, coordination and maintainability.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial electrical distribution systems.
- Manufacturing and process facilities.
- Commercial building power distribution.
- Infrastructure electrical installations.
- Critical distribution systems requiring integrated ground-fault protection.
