1SCA022568R2300 ABB OTR125B4B 125 A 45 kW 4-Pole IP65 Stainless Steel Enclosed Switch

Why Choose the ABB OTR125B4B Stainless Steel Enclosed Switch?

The ABB OTR125B4B, product ID 1SCA022568R2300, is a robust 4-pole 125 A stainless steel enclosed switch-disconnector designed for dependable isolation of industrial machinery, motors and electrical distribution equipment. It provides a 90 A AC-23A rating at 415 V and a motor switching capacity of 45 kW at 415 V.

The OTR125B4B combines ABB load-break switching technology with a durable IP65 stainless steel enclosure. A black pistol operating handle provides clear I-O / ON-OFF indication and incorporates cover interlocking with a defeatable interlock function, supporting controlled access during operation and maintenance.

Designed for demanding industrial environments, the OTR125B4B features B-flange cable entries at the top and bottom and is supplied with N and PE terminals. Its 300 × 200 × 135 mm enclosure and four-pole switching configuration provide a practical solution for applications requiring simultaneous isolation of three phases and an additional conductor.

Heavy-Duty Four-Pole Isolation in Stainless Steel

A four-pole enclosed switch-disconnector provides simultaneous isolation of four conductors, making it suitable for installations where an additional conductor must be switched alongside the three phases. The ABB OTR125B4B combines this 4-pole switching capability with a stainless steel IP65 enclosure for industrial environments where a robust metal housing is required.

With a 125 A AC-22A rating, 90 A AC-23A rating and 45 kW motor capacity at 415 V, the OTR125B4B is designed for substantial machinery and load-breaking duties. The interlocked black pistol handle, N and PE terminals and top-and-bottom B-flange cable entries provide a purpose-built enclosed solution for local isolation and industrial maintenance.

Typical Applications

• Industrial motor isolation up to 45 kW at 415 V.
• Four-pole three-phase and neutral isolation.
• Industrial machinery and production equipment.
• Food and beverage processing installations.
• Pumps, fans and ventilation systems.
• Conveyors and material handling equipment.
• Process plant and manufacturing machinery.
• Industrial electrical distribution equipment.
• Plant maintenance and local isolation points.
