1SCA022513R8510 ABB 315A 3-Pole IP65 EMC Enclosed Safety Switch

Why Choose the ABB OT315KUUR3TZ 315A EMC Enclosed Safety Switch?

The ABB OT315KUUR3TZ is a heavy-duty 315 A 3-pole steel-sheet enclosed EMC safety switch designed for dependable load switching and electrical isolation in industrial installations where electromagnetic compatibility is an important consideration. Identified by ABB order code 1SCA022513R8510, it belongs to ABB product group 311019 – Metal Enclosed (Loadbreak) and combines ABB OT switch-disconnector technology with an EMC-oriented enclosed design.

Designed for high-current local isolation, the OT315KUUR3TZ uses an IP65 steel-sheet enclosure with a blank cable-entry plate at the top and four ring-flange openings at the bottom. This arrangement provides a defined bottom-entry cable route while allowing suitable ring flanges and compression glands to be selected separately for the installation.

With a rated current of 315 A and a 3-pole configuration, the OT315KUUR3TZ is suitable for substantial three-phase loads. Its AC-23A motor switching capacity is 160 kW / 315 A at 415 V and 250 kW / 315 A at 690 V, making it suitable for large motors, drives, machinery and industrial power systems.

Reliable EMC-Sensitive Electrical Isolation

The ABB OT315KUUR3TZ provides a dependable local isolation point for high-current three-phase machinery, motors and drive systems where electromagnetic compatibility needs to be considered. Its IP65 steel-sheet enclosure provides robust environmental protection, while the black I-O / ON-OFF handle gives clear manual control for maintenance, servicing and equipment isolation.

The enclosure uses a blank top cable-entry plate and four ring-flange openings at the bottom, with two cover flanges included. The 2NO + 1NC auxiliary contacts are wired to terminal blocks for convenient integration with signalling and interlocking circuits, while a PE terminal is also provided. Compression glands are ordered separately, and shielded cables should be used where effective EMC protection is required.

Typical Applications

• Variable-speed drive and motor installations.
• EMC-sensitive industrial machinery.
• Large three-phase motor isolation.
• Industrial automation and production equipment.
• Pumps, fans and ventilation systems.
• Manufacturing and processing machinery.
• Local maintenance and electrical isolation points.
