Honeywell Series NT Toggle Switch, 277V AC Contact AC Voltage, 20A Switch Contact Current - 2NT1-8


This toggle switch provides a compact, rugged switching solution for control panels and equipment in industrial settings. Designed for bushing mounting, it offers dual-pole double-throw contact capability and supports alternating current use up to 277V AC, making it suitable for varied control and routing tasks without detailing mechanical dimensions.

Features and Benefits:


• DPDT contact arrangement enables independent two-circuit switching, improving system flexibility
• 20A contact rating supports high-current switching for robust load control
• Maintained and momentary operation modes allow latching or transient actuation
• Screw terminals ensure secure conductor connection for Durable installations
• IP68 and IP67 ingress protection permit immersion and dust-tight operation
• Rated for operation from -40°C to 71°C for wide temperature deployment

Applications


• Suitable for industrial control panels requiring dual-circuit selection
• Ideal for machine-tool control where both momentary and maintained actions are needed
• Used for switching high-current auxiliary circuits in electrical distribution systems
• Can be used for outdoor installations exposed to dust and temporary submersion
• Used with automation equipment that requires secure screw-terminal connections

How is the switch secured to a panel?


It is designed for bushing-mount installation, fitting through a panel aperture and secured at the mounting point.

What Terminal type should installers expect for wiring?


Connections are MADE via screw terminals that accept stranded or solid conductors for dependable electrical contact.

Can it be used where frequent temperature swings occur?


Yes, it is specified to function across a -40°C to 71°C range, accommodating environments with substantial thermal variation.

What approvals cover its use in regulated installations?


The device meets recognised CSA, CE and UL standards applicable to electrical switching components.
