FAQs
Installation begins with confirming enclosure compatibility for flush mounting and Pauluhn 27S series fit. Verify panel cutout matches the 2.75 inch depth, 4.5 inch height, and 2.38 inch width. Mount using the standard hardware, connect the single-pole switch to the 277 VAC circuit, and ensure CE or local codes for ordinary locations are followed. The copper-free aluminum housing facilitates easier handling and corrosion resistance during long-term operation.
The 2722AF is rated for 20A at 277 VAC and configured as a single-pole switch. This makes it suitable for common control circuits in industrial panels, motors, and solenoid systems operating at standard line voltage. Its Pauluhn 27S compatibility ensures predictable behavior within Pauluhn enclosure systems, reducing wiring complexity and improving reliability in automation applications.
Yes. The product explicitly lists Ordinary/Non-Hazardous Locations as its area classification, making it appropriate for general manufacturing floors, warehouses, and similar environments. Its copper-free aluminum housing provides corrosion resistance, while the flush-mount design helps keep panels neat and compliant with standard installation practices in non-hazardous areas.
The 2722AF notes area classification as Ordinary/Non-Hazardous Locations, which guides where it can be installed. Its copper-free aluminum construction contributes to durability and corrosion resistance in typical industrial settings. When planning installation, verify compliance with local electrical codes and the customer’s internal standards for control devices in non-hazardous environments.
The copper-free aluminum housing reduces corrosion-related wear, lowering maintenance cycles and replacement risk in harsh environments. Its light weight and flush-mount design simplify installation and field servicing, potentially reducing labor costs. The single-pole configuration minimizes wiring complexity, contributing to faster commissioning and lower lifecycle costs in automation systems.
