ABB OT Plus OT16G1-3MS16 16 A 3-polige lastscheider met directe aandrijving

The ABB OT Plus OT16G1-3MS16 distinguishes itself from typical switch-disconnectors by pairing a 16 A rating with a robust 690 V AC operational voltage in a compact G1 frame. This combination makes it exceptionally versatile for three-phase industrial applications where space is at a premium but performance cannot be compromised. The direct mounted MS16 handle provides clear ON/OFF indication and ergonomic operation, ensuring safe and immediate manual control.

Highlights

• Rated operational current of 16 A (AC-21A, AC-22A, AC-23A) for versatile load handling.
• High rated operational voltage of 690 V AC, ideal for industrial power distribution.
• Direct mounted handle (MS16 type, black) for immediate manual control and visible switching state.
• Compact G1 frame size with base or DIN rail mounting options (adapter required for DIN rail).
• Robust construction with IP20 terminal protection and IP65 front protection when handle is mounted.
• Meets IEC 60947-3 standards for switch-disconnectors.

In daily use

In practice, the OT16G1-3MS16 excels in applications requiring frequent manual isolation, such as machine control panels, HVAC systems, and small motor circuits. The screw terminals accept conductors from 1.5 to 6 mm², ensuring secure connections. With a mechanical and electrical durability of 20,000 cycles, it delivers long-term reliability. The operating temperature range of -25 to +70 °C allows deployment in harsh conditions, while the low power loss per pole of 0.8 W contributes to energy efficiency.
