Why Choose the ABB E1N/MS 1000 4-Pole Withdrawable Switch-Disconnector?
The ABB E1N/MS 1000, order code 1SDA059256R1, is a robust SACE Emax switch-disconnector moving part designed for isolation and switching in high-current low-voltage electrical distribution systems. Part of the proven ABB SACE Emax E1N/MS series, this four-pole device has a rated current of 1000 A and uses a withdrawable configuration for integration into compatible Emax switchgear.
Unlike an overcurrent-protective circuit breaker, the E1N/MS is configured as a switch-disconnector, providing dependable switching and circuit isolation where protection is provided elsewhere in the installation. Its E1N performance level and heavy-duty SACE Emax construction make it suitable for industrial switchboards, distribution assemblies and other installations requiring reliable high-current isolation.
This version is a four-pole withdrawable moving part with a rated operational voltage of up to 690 V AC. Its withdrawable design supports convenient inspection, servicing and isolation within compatible switchgear, while a rated short-time withstand current of 50 kA for 1 s provides robust performance under demanding electrical conditions.
