The EDSC3140 GB delivers 20A at 120–277V in a four-pole, four-way configuration, enabling reliable multi-circuit control from a single station and reducing panel footprint. This directly improves process reliability and minimizes wiring errors on installation projects in hazardous locations, delivering measurable uptime improvements and lower project risk. Through-feed wiring with two 1" hubs simplifies field connections, accelerates commissioning, and supports cleaner cable management, which translates to shorter installation windows and fewer on-site adjustments. The rugged Feraloy iron alloy enclosure provides enhanced impact resistance and heat tolerance, extending service life in challenging environments and lowering maintenance costs over the asset lifecycle. Compliance with NEC/CEC and hazardous-location ratings (Class I, Division 1, Group B) minimizes regulatory risk and simplifies cross-border deployments. The single-gang, 1" trade-size enclosure with an integrated switch (Enclosure type: With switch) facilitates straightforward integration into standard control panels, reducing modification expenses and enabling faster system upgrades.

FAQs

For EDSC3140 GB, use a certified hazardous-location installation with a suitable enclosure rated for Class I Division 1. Mount the unit in a single-gang space, connect wiring through the two 1" hubs, and route conductors per NEC/CEC guidelines. Ensure the switch is protected from moisture and dust, and verify that the operating voltage remains within 120–277V and the load stays within 20A.
The device is rated for 20A and 120–277V AC, arranged as a four-pole, four-way control with a 1" trade size and two 1" hubs. It is designed for single-gang installations and supports through-feed wiring, enabling multiple circuits to be controlled from one station while complying with NEC/CEC in hazardous locations.
Yes. The EDSC3140 GB carries NEC/CEC standards alignment and is rated for Hazardous/Classified Locations with Class I Division 1 Group B. It also aligns with NEMA ratings 7, 9, and 3, providing the regulatory confidence needed for chemical plants, refineries, and other high-risk environments.
Typical applications include process control in chemical processing facilities, mining operations, and refinery environments where reliable switch control is required in hazardous areas. The combination of 20A 120–277V operation, four-pole switching, and through-feed wiring makes it suitable for multi-circuit control in compact, rugged enclosures.
The unit employs a Feraloy iron alloy enclosure for durability, reducing maintenance intervals in harsh environments. Its rugged construction and compliant ratings minimize downtime and regulatory risk, delivering a lower total cost of ownership over the asset lifecycle and faster return on investment through improved uptime and simplified upgrades.
