1SDA073154R1 ABB E4.2V 3200 Ekip Touch LI 4p WMP Air Circuit Breaker

Why Choose the ABB E4.2V 3200 Ekip Touch LI 4p WMP Air Circuit Breaker?

The ABB E4.2V 3200 Ekip Touch LI 4p WMP, order code 1SDA073154R1, is a high-performance four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection and switching in demanding low-voltage power distribution systems. Rated at 3200 A, this withdrawable moving part combines the E4.2 frame with ABB's V short-circuit performance level and an advanced Ekip Touch LI electronic trip unit.

The Ekip Touch LI release provides long-time overload (L) and instantaneous short-circuit (I) protection. Long-time protection is adjustable from 0.4–1 × In, while instantaneous protection is adjustable from 1.5–15 × In. A touch-sensitive display provides an intuitive interface for configuring protection settings and accessing operating information.

With a rated operational voltage of 690 V AC, rated insulation voltage of 1000 V AC and an ultimate short-circuit breaking capacity of 150 kA at 380–440 V AC, the E4.2V 3200 is engineered for networks with very high prospective fault currents. Its four-pole withdrawable moving-part construction supports efficient inspection, servicing and replacement when installed with the corresponding ABB SACE Emax 2 fixed chassis.

High-Performance Protection for Critical Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 provide switching, isolation and protection for high-current low-voltage electrical networks. The E4.2V platform combines a substantial 3200 A continuous-current rating with very high short-circuit breaking performance, making it suitable for main distribution systems where prospective fault currents demand robust circuit protection.

The Ekip Touch LI trip unit provides adjustable long-time overload and instantaneous short-circuit protection through an intuitive touch-sensitive interface. Combined with the E4.2V platform's 150 kA breaking capability at 380–440 V AC, this configuration is well suited to high-current feeders, transformer circuits and main distribution applications in appropriately engineered electrical networks.

Typical Applications

• Main low-voltage distribution switchboards.
• High-fault-level industrial electrical networks.
• Transformer secondary protection.
• Main and high-current feeder protection.
• Manufacturing plants and process facilities.
• Data centres and critical power infrastructure.
• Commercial and infrastructure electrical distribution.
• Large switchgear and power distribution installations.
