1SDA060849R1 ABB E3H-A 3200 PR123/P-LSIG 3200A 3-Pole Withdrawable Moving Part

Why Choose the ABB 1SDA060849R1 E3H-A 3200 PR123/P-LSIG Moving Part?

The ABB 1SDA060849R1, identified as E3H-A 3200 PR123/P-LSIG In=3200A 3p W MP, is a three-pole moving part for a withdrawable SACE Emax E3H-A air circuit breaker. Designed for demanding low-voltage power-distribution systems, it combines a substantial 3200 A rated current with ABB’s advanced PR123/P electronic overcurrent release.

The fitted PR123/P-LSIG electronic trip unit uses an R3200 rating plug and provides long-time, short-time, instantaneous and ground-fault protection. This comprehensive LSIG arrangement supports selective protection against overloads, short circuits and ground faults in critical industrial and commercial distribution systems.

As a withdrawable moving part, the 1SDA060849R1 is designed to interface with a compatible SACE Emax E3 fixed part. The withdrawable architecture allows the breaker moving section to be removed for isolation, inspection, maintenance or replacement while the fixed switchboard connections remain installed.

Key Advantages

• Genuine ABB SACE Emax E3H-A moving part for withdrawable circuit-breaker installations.

Advanced LSIG Protection in Withdrawable Emax Switchgear

The ABB SACE Emax withdrawable architecture separates the removable circuit-breaker moving part from the fixed section installed in the switchboard. The 1SDA060849R1 can therefore be withdrawn from its compatible E3 fixed part for isolation, inspection, servicing or replacement without dismantling the principal fixed switchboard connections.

Its PR123/P-LSIG electronic release provides comprehensive protection: long-time protection responds to sustained overloads, short-time protection supports coordinated response to short circuits, instantaneous protection provides rapid interruption of severe faults, and ground-fault protection addresses unintended current paths to earth. Combined with the 3200 A E3H-A platform, this provides a robust and service-friendly solution for critical high-current distribution systems.

Typical Applications

• Industrial low-voltage main distribution switchboards.
• ABB SACE Emax E3H-A withdrawable circuit-breaker installations.
• High-current main incoming circuit protection.
• High-capacity feeder protection.
• Manufacturing and process-industry switchgear.
• Commercial and infrastructure power-distribution systems.
• Distribution systems requiring ground-fault protection.
• UL switchboards requiring 3200 A LSIG electronic protection.
