Frequently Asked Questions

What protection functions does the Ekip Dip LSI release provide?

The Ekip Dip LSI release provides three levels of protection: Long-time (L) for overload protection, Short-time (S) for delayed short-circuit protection, and Instantaneous (I) for immediate response to high fault currents. Settings are configured via DIP switches directly on the release unit.

What is the breaking capacity of the E1.2B 1250 Ekip Dip LSI 3p F F at 400 V AC?

The rated ultimate breaking capacity (Icu) is 42 kA at 400 V AC, as specified in the SACE Emax2 product family documentation.

Is this breaker withdrawable or fixed?

This is a fixed-mount (F F) unit. It is designed for permanent installation within a switchboard or distribution panel. A withdrawable variant is available separately in the Emax2 product range.

What are the physical dimensions and weight?

The E1.2B 1250 Ekip Dip LSI 3p F F measures 210 mm (width) × 296 mm (height) × 183 mm (depth) and weighs 14 kg.
