Why Choose the ABB OT250ERRR3TZ Enclosed Safety Switch?
The ABB OT250ERRR3TZ is a heavy-duty 250 A three-pole enclosed safety switch-disconnector designed for dependable load switching and electrical isolation in demanding industrial environments. It combines ABB OT switch-disconnector technology with a rigid AISI 316L acid-proof stainless-steel enclosure, making it suitable for applications where corrosion resistance, mechanical durability and reliable isolation are important.
Designed for both indoor and outdoor installations, the OT250ERRR3TZ features an IP65 enclosure, stainless-steel I-O / ON-OFF operating handle, hinged door and door lock. The cover is mechanically interlocked so that it cannot normally be opened while the switch is ON, while a defeatable interlock allows authorised access when required for procedures such as thermographic inspection.
The OT250ERRR3TZ provides an AC-23A motor switching capability of 132 kW at 400 V and 200 kW at 690 V. Factory-supplied 2NO+1NC auxiliary contacts and a PE terminal support integration into industrial control systems, while prepared ring-flange cable openings at the top and bottom allow suitable standard or EMC cable flanges to be selected for the installation.
