1SCA022569R7670 ABB OTR100BA4U 100 A 4-Pole IP65 Stainless Steel Enclosed Switch

Why Choose the ABB OTR100BA4U Stainless Steel Enclosed Switch?

The ABB OTR100BA4U, product ID 1SCA022569R7670, is a robust 4-pole 100 A stainless steel enclosed switch-disconnector designed for dependable isolation of industrial machinery, motors and electrical distribution equipment. At 415 V it is rated at 100 A AC-22A and 80 A AC-23A, with a motor switching capacity of 37 kW.

The OTR100BA4U combines ABB load-break switching technology with a durable IP65 stainless steel enclosure. It is supplied with a red-yellow pistol operating handle featuring clear I-O / ON-OFF indication, cover interlocking and a defeatable interlock function, providing a clearly identifiable local isolation point for industrial equipment.

Designed for flexible cable installation, the OTR100BA4U has blank cable-entry areas at the top and bottom, allowing the enclosure to be prepared to suit the installation. N and PE terminals are included, while the 300 × 200 × 135 mm enclosure provides a substantial yet practical housing for four-pole industrial isolation.

Heavy-Duty Four-Pole Isolation in Stainless Steel

A four-pole enclosed switch-disconnector provides simultaneous disconnection of four conductors, making it suitable for applications where an additional conductor must be isolated alongside the three phases. The ABB OTR100BA4U combines this 4-pole switching capability with an IP65 stainless steel enclosure for industrial environments requiring robust enclosed isolation.

With a 100 A AC-22A rating, 80 A AC-23A rating and 37 kW motor capacity at 415 V, the OTR100BA4U is suitable for substantial motor and machinery loads. Its blank top and bottom cable-entry arrangement allows the enclosure to be adapted to the required cable system, while the interlocked red-yellow handle provides clear local operation.

Typical Applications

• Industrial motor isolation up to 37 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.
