1SDA071896R1 ABB E6.2H 5000 Ekip Touch LSIG 4p FHR Air Circuit Breaker 5000 A

Why Choose the ABB E6.2H 5000 Ekip Touch LSIG 4p FHR Air Circuit Breaker?

The ABB E6.2H 5000 Ekip Touch LSIG 4p FHR, order code 1SDA071896R1, is a high-current four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range. Designed for demanding low-voltage power distribution, it combines a 5000 A rated current with the E6.2H performance class and an advanced Ekip Touch LSIG electronic protection release.

The Ekip Touch LSIG solid-state trip unit provides long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. Its electronic architecture and touch interface support configurable protection and monitoring, making the breaker well suited to installations requiring comprehensive circuit protection and selective coordination.

With a 100 kA breaking capacity and operation at up to 690 V AC, the E6.2H 5000 is engineered for high-capacity distribution systems. This version is supplied as a fixed four-pole breaker with rear horizontal terminals and is fitted with four auxiliary contacts for circuit-breaker open and closed position indication.

Comprehensive LSIG Protection for High-Current Distribution

The Ekip Touch LSIG release combines four complementary protection functions for demanding electrical distribution systems. Long-time protection responds to sustained overloads, short-time protection supports selective fault coordination, instantaneous protection provides rapid interruption of severe short circuits, and earth-fault protection detects potentially damaging current flowing to earth.

Combined with the E6.2H frame's 5000 A current rating and 100 kA breaking capacity, this comprehensive LSIG protection makes the 1SDA071896R1 particularly suitable for high-capacity main switchboards and distribution circuits where substantial load currents, high prospective fault levels and configurable electronic protection must be accommodated.
