Why Choose the ABB E1.2N 1000 Ekip Dip LSI 4p WMP Air Circuit Breaker?
The ABB E1.2N 1000 Ekip Dip LSI 4p WMP, order code 1SDA072782R1, is a four-pole withdrawable air circuit breaker moving part from the ABB SACE Emax 2 range. Designed for low-voltage AC power distribution, it combines a 1000 A rated current with the E1.2N performance level and an Ekip Dip LSI solid-state electronic trip unit.
The Ekip Dip LSI release provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection. Its adjustable protection thresholds support effective coordination within distribution networks, helping protect cables, busbars, switchgear and connected electrical equipment against overload and short-circuit conditions.
With an ultimate short-circuit breaking capacity of 66 kA at 400 V AC, the E1.2N platform is suited to demanding distribution applications. The withdrawable construction connects through a separate fixed chassis, allowing the breaker moving part to be withdrawn for inspection and servicing while supporting maintainable switchboard designs.
Key Advantages
- 1000 A rated current for demanding low-voltage distribution applications.
- Four-pole configuration for switching and protecting four-conductor systems.
- Ekip Dip LSI electronic trip unit with adjustable protection thresholds.
- Long-time, short-time delayed and instantaneous protection functions.
- 66 kA ultimate short-circuit breaking capacity at 400 V AC.
- Short-time delayed release adjustment from 600–10000 A.
- Instantaneous release adjustment from 1500–15000 A.
- Withdrawable moving-part construction supports convenient inspection and maintenance.
Key Features
- ABB SACE Emax 2 E1.2N air circuit breaker moving part.
- 1000 A rated uninterrupted current.
- 4-pole construction.
- Ekip Dip LSI solid-state electronic protection release.
- Long-time overload protection.
- Short-time delayed short-circuit protection.
- Instantaneous short-circuit protection.
- Overload release adjustable from 400–1000 A.
- 690 V AC rated voltage.
- Four auxiliary changeover contacts.
- Open/closed circuit breaker position indication.
- Optional motor operator capability.
Selective LSI Protection for Low-Voltage Distribution
The Ekip Dip LSI release provides three complementary protection functions for low-voltage distribution systems. Long-time protection responds to sustained overloads, short-time protection supports selective coordination during short-circuit events, and instantaneous protection provides rapid response to severe fault currents.
The withdrawable E1.2N construction is particularly suitable for switchboards where serviceability and operational flexibility are important. The breaker moving part connects through a separate chassis section and can be withdrawn when required, while four auxiliary changeover contacts and open/closed position indication support integration with switchboard signalling and control systems.
Typical Applications
- Main low-voltage distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical distribution.
- Manufacturing and process facilities.
- Infrastructure and utility installations.
- Transformer distribution systems.
- Generator and installation protection.
- Withdrawable switchgear requiring selective LSI protection.
