Why Choose the ABB E3N/MS 2500 3P F HR Switch Disconnector?
The ABB E3N/MS 2500 3P F HR, order code 1SDA058973R1, is a heavy-duty SACE Emax air switch disconnector designed for high-current switching and isolation in low-voltage power distribution systems. Built on the ABB E3 frame, this three-pole unit provides a rated uninterrupted current of 2500 A and uses a fixed installation format with rear flat horizontal terminals.
The E3N/MS 2500 combines robust SACE Emax construction with the N short-circuit performance level. It provides a rated short-time withstand current of 65 kA for 1 s and 65 kA for 3 s, together with a rated short-circuit making capacity of 143 kA peak, providing strong withstand performance for demanding industrial distribution systems.
Rated for operation up to 690 V AC or 250 V DC, with a rated insulation voltage of 1000 V and rated impulse withstand voltage of 12 kV, the E3N/MS 2500 is engineered for substantial low-voltage distribution duties. As an ABB /MS switch disconnector, it retains the overall Emax architecture and accessory capability of the corresponding circuit-breaker platform while operating without an overcurrent trip unit.
Key Advantages
- Heavy-duty 2500 A SACE Emax switch disconnector for high-current distribution and isolation.
- Three-pole fixed construction for robust permanent switchboard installations.
- Rear flat horizontal terminals provide a practical connection arrangement for switchboard busbars.
- Rated for operation up to 690 V AC or 250 V DC.
- 65 kA short-time withstand current for both 1 s and 3 s.
- AC-23A utilisation capability supports switching of motor loads and other highly inductive loads.
Key Features
- ABB SACE Emax E3N/MS series.
- 2500 A rated uninterrupted current.
- Three-pole (3P) construction.
- Fixed (F) installation version.
- Rear flat horizontal (HR) terminals.
- 690 V AC / 250 V DC rated operational voltage.
- 1000 V rated insulation voltage.
- 12 kV rated impulse withstand voltage.
- N short-circuit performance level.
- 143 kA peak rated short-circuit making capacity.
Reliable High-Current Isolation for Power Distribution
ABB /MS switch disconnectors are derived from the corresponding SACE Emax circuit breakers and retain their overall dimensions and accessory possibilities while omitting the electronic overcurrent trip unit. The E3N/MS 2500 therefore provides dedicated switching and isolation where circuit protection is supplied separately, while its AC-23A utilisation category supports switching of motor loads and other highly inductive circuits within its applicable ratings.
With its 2500 A current rating, three-pole fixed construction and 65 kA short-time withstand capability, the E3N/MS 2500 is well suited to demanding industrial switchboards. Rear flat horizontal terminals facilitate integration with engineered busbar systems, while the established SACE Emax mechanism provides the durability required for long-term power distribution service.
Typical Applications
- Industrial low-voltage power distribution switchboards.
- Main incoming and distribution isolation.
- High-current fixed switchgear assemblies.
- Industrial plants and manufacturing facilities.
- Commercial and infrastructure power distribution systems.
- High-current feeder and busbar isolation.
