1SCA022562R1420 ABB Steel Enclosed Switch-Disconnector 16 A 4 Pole IP65

Why Choose the ABB OTL16B4M Enclosed Switch-Disconnector?

The ABB OTL16B4M is a compact 16 A four-pole steel enclosed switch-disconnector designed for dependable local isolation of industrial machinery, motors and electrical distribution circuits. With ABB product ID 1SCA022562R1420, this unit combines four-pole switching with a durable metal enclosure for demanding industrial installations.

As part of the ABB OTL enclosed switch-disconnector range, the OTL16B4M features an IP65 steel sheet enclosure and a black selector-type operating handle with I-O / ON-OFF indication. Its enclosed construction provides protection against dust and water ingress, while the door interlock helps support controlled access during operation and maintenance.

The OTL16B4M is rated at 16 A AC-22A at 415 V and 16 A AC-23A at 415 V, with a motor switching capability of 7.5 kW at 415 V. Its four-pole configuration allows four conductors to be switched simultaneously, making it suitable for applications where additional isolation beyond a conventional three-pole arrangement is required.

Key Advantages

• Compact 16 A steel enclosed switch-disconnector for industrial isolation.
• Four-pole configuration for simultaneous switching of four conductors.
• 16 A AC-22A and AC-23A ratings at 415 V.

Four-Pole Isolation for Industrial Electrical Systems

Four-pole switch-disconnectors such as the ABB OTL16B4M enable four conductors to be disconnected simultaneously through a single operating mechanism. This makes the configuration useful for electrical systems requiring an additional switched conductor alongside the three phases, subject to the design and isolation requirements of the installation.

The OTL16B4M combines IP65 steel enclosure protection with a compact footprint and clearly operated black selector handle. Its 16 A AC-23A rating and 7.5 kW motor switching capability at 415 V make it suitable for smaller industrial motors, machinery and distribution circuits requiring robust four-pole local isolation.

Typical Applications

• Industrial machinery local isolation.
• Four-pole electrical distribution circuits.
• Three-phase systems requiring an additional switched conductor.
• Motors up to 7.5 kW at 415 V under the specified AC-23A duty.
• Conveyor and material handling equipment.
• Pumps, fans and ventilation systems.
• Manufacturing and production machinery.
• Processing and packaging equipment.
