ABB 3-Pole Screw Mount Switch Disconnector with IP65 Rating 0A, Series OTR

ABB 1SCA022569R5970 OTR32BA3M is a 3-pole screw mount switch disconnector optimized for both indoor and outdoor industrial applications with an IP65 ingress protection rating. This switch disconnector belongs to the OTR series and features a rigid enclosure made of stainless steel class AISI304, providing robust mechanical protection and resistance against corrosion.

The enclosure includes a hinged door with a locking mechanism and an interlocked cover that prevents the cover from being opened when the switch is in the ON position, enhancing user safety. The interlock function can be overridden temporarily for thermographic inspections. The product is suitable for use in electrical automation, manufacturing, HVAC, and various construction settings requiring reliable isolation of electrical circuits.

It features screw clamp type terminals for secure wiring connections and supports mounting via screws. The handle is black for easy identification and operational control. The rated operational voltage is 750V, and the switch supports a switching current of 0A with provision for mounting up to two auxiliary contacts (2NO/2NC) to enable additional control and signaling functions.

The disconnector has a compact size with dimensions of 150mm width, 100mm length, and 100mm depth, making it convenient for panel mounting. Cable entries are of knockout type, allowing flexible cable entry options including neutral and protective earth terminals. This IP65 rated switch disconnector offers protection against dust ingress and water jets, making it ideal for tough industrial environments.

Compliance with RoHS directives ensures that the product meets environmental and sustainability standards. Its operating temperature range starts from 0°C, suitable for applications in controlled environments but not recommended for freezing conditions. The ABB OTR series screw mount switch disconnector is an essential component for safe electrical system isolation and maintenance in industrial automation, electrical equipment control, and power distribution.

The enclosure is constructed from rigid stainless steel class AISI304 for durability. Equipped with a hinged door with door lock and interlocked cover preventing opening when switch is on. Rated operational voltage is 750V suitable for various industrial uses.

Includes screw clamp terminals and accommodates up to 2NO/2NC auxiliary contacts. Designed for mounting via screws with a robust handle in black color. IP65 ingress protection ensures safety against dust and water jet penetration.

Minimum operating temperature is 0°C, supporting stable operation under moderate climate conditions. Dimensions are 150mm width, 100mm length, and 100mm depth for compact installation. Cable entries are knockout types, including N- and PE terminals for grounding.
