ABB Sace Emax2 E1.2 B630 air circuit breaker, 630A, 690V low voltage protective switch

Product Description

The ABB Sace Emax2 E1.2 B630 is a compact air circuit breaker built for reliable low-voltage power distribution protection, rated at 630A nominal current and 690V operational voltage. As part of the ABB Sace Emax2 series, this ABB Sace Emax2 E1.2 B630 combines robust short-circuit and overload protection with integrated power measurement and digital communication capacity, moving beyond basic breaking functions to serve as an on-site power manager for electrical panels.

The ABB Sace Emax2 E1.2 B630 follows IEC 60947-2 standards and supports isolation functions when contacts are open, meeting safety requirements for maintenance work on downstream circuits. Its Ekip electronic trip unit delivers adjustable protection curves, precise energy metering with Class 1 accuracy, event logging and alarm recording. Users can configure overload, short delay and instantaneous protection parameters directly, and view real-time electrical data through local display or remote access. This ABB Sace Emax2 E1.2 B630 is available in fixed or withdrawable versions, with front terminal connection options that simplify busbar wiring inside compact switchgear cabinets.

For performance, the ABB Sace Emax2 E1.2 B630 handles 50/60Hz AC systems up to 690V, with high short-time withstand current to secure selectivity in multi-level distribution networks. Mechanical and electrical endurance is engineered for frequent switching cycles in industrial and commercial environments. Built-in Bluetooth and multiple industrial communication protocols allow seamless integration into SCADA, BMS and ABB Ability cloud platforms, supporting remote monitoring, predictive maintenance and load management strategies.

This ABB Sace Emax2 E1.2 B630 suits a wide scope of applications including factory power centers, building main distribution boards, data center auxiliary power circuits and marine low voltage systems. Its compact footprint helps reduce the overall dimension of switchgear, while standardized accessories across the whole ABB Sace Emax2 range cut inventory and engineering workload. Installation, testing and replacement of the ABB Sace Emax2 E1.2 B630 can be finished efficiently, minimizing downtime for critical power loads.
