1SCA132669R1001 ABB 32 A 3-Pole 11 kW 415 V Enclosed Safety Isolator

Why Choose the ABB OTU32BA3MS2 Enclosed Safety Isolator?

The ABB OTU32BA3MS2, product ID 1SCA132669R1001, is a robust 3-pole enclosed safety switch-disconnector designed for dependable local isolation of motors, machinery and industrial electrical equipment. It is rated at 32 A AC-22A at 415 V and 23 A AC-23A at 415 V, with a motor switching capacity of 11 kW at 415 V.

The OTU32BA3MS2 combines an ABB switch-disconnector with a rigid glass-reinforced polycarbonate enclosure. The enclosure is UV protected and provides IP65 protection for indoor and outdoor installations. A highly visible red-yellow round operating handle provides clear I-O / ON-OFF indication and can be secured with up to three padlocks for controlled safety isolation.

Designed for practical industrial installation, the OTU32BA3MS2 provides cable entry from both the top and bottom through knock-out openings for parallel cables. The switch is designed for a five-wire system and includes a fixed neutral terminal and PE terminal, while its compact 161 × 100 × 115 mm enclosure makes it suitable for installation close to machinery and equipment.

Reliable Safety Isolation for Motors and Machinery

An enclosed safety switch-disconnector provides a clearly identifiable means of disconnecting electrical equipment from its supply during servicing, inspection and maintenance. The ABB OTU32BA3MS2 combines a 3-pole switching mechanism with a highly visible red-yellow handle, helping personnel quickly identify the local safety isolation point on three-phase machinery and equipment.

With its 23 A AC-23A rating and 11 kW motor capacity at 415 V, the OTU32BA3MS2 is particularly suited to local motor isolation. Its IP65 UV-protected enclosure, padlockable handle and top-and-bottom knock-out cable entries provide a practical solution for industrial installations requiring secure and accessible electrical isolation.

Typical Applications

• Motor isolation up to 11 kW at 415 V.
• Three-phase machinery isolation.
• Industrial safety isolation points.
• Pumps, fans and ventilation equipment.
• Conveyors and material handling systems.
• Production and packaging machinery.
