Eaton ER4X-25N6SB Enclosed Rotary Disconnect - NEMA 4X
Part Number: ER4X-25N6SB
Quick Summary
ER4X-25N6SB enclosed rotary disconnect switch by Eaton isolates circuits in electrical protection panels up to 600 V and 25 A. In real-world installations, downtime for manual shutoffs and safety concerns can slow maintenance and compromise safety. This unit carries CE marking and a NEMA 4X enclosure, and its 600 V rating aligns with common industrial distribution practices. Designed for panel installs where space is at a premium, the compact footprint and selector functionality streamline wiring and testing while improving downtime metrics. Its non-fused design reduces replacement complexity and can lower total cost of ownership when used in non-critical feed paths. Customers report faster commissioning and simpler spare-part management thanks to the standardized Bussmann series family.

Eaton Specification Sheet - ER4X-25N6SB
Feature: Enclosed, non-fused rotary disconnect with selector; Business impact: Provides reliable, visible isolation of power paths, reducing arc flash exposure during maintenance and enabling safer lockout-tagout procedures. Application: Ideal for control panels and switchgear where fast, fail-safe shutdown is required, including machine tools, conveyors, and processing lines. Feature: Electrical rating of 600 V and 25 A; Business impact: Supports typical industrial loads without overpowering the protection scheme, helping protect downstream equipment while complying with standard distribution practices. Application: Suitable for feeder circuits in machinery and equipment panels where a compact, non-fused disconnect is preferred for routine isolation. Feature: NEMA 4X enclosure and CE marking; Business impact: Delivers rugged enclosure protection against dust, water, and washdown environments while meeting international compliance requirements. Application: Suitable for industrial environments that demand durability and regulatory alignment, including food and beverage, packaging lines, and outdoor installations. Feature: Non-fused selector design; Business impact: Reduces spare-part variety and simplifies maintenance planning while providing clear operator control. Application: Enables straightforward selection and isolation in multi-step control sequences, improving reliability of startup and testing procedures. Feature: Lightweight, compact form factor (0.1 lb, 0.1 in dimensions); Business impact: Eases installation, reduces cabinet footprint, and lowers labor costs during retrofits or new builds. Application: Particularly beneficial for retrofits where space is constrained or where multiple switches are deployed across panels. Feature: Integration with Bussmann series catalog and components; Business impact: Streamlines procurement and spare-parts management across maintenance teams. Application: Aligns with established Eaton Bussmann series catalog practices to reduce downtime and simplify stocking.

FAQs
Installation should begin with ensuring the panel opening matches the switch mounting and that the supply is de-energized. Verify the 600 V rating and 25 A current handling, then mount the ER4X-25N6SB in the designated position, connect the selector wiring per Eaton's datasheet, and secure all connections. Confirm proper enclosure sealing to maintain NEMA 4X integrity and perform a functional test to validate safe isolation.
Key ratings are 600 V maximum voltage, 25 A current rating, and a NEMA 4X enclosure. These specifications define the range of loads and environmental conditions the switch can safely isolate. Ensure the connected equipment and conductors are rated accordingly and that the installation complies with CE marking requirements for regulatory conformity.
Yes. The NEMA 4X enclosure provides rugged protection against dust and water ingress, making it suitable for outdoor or washdown environments common in manufacturing lines. For best results, seal all mating surfaces and ensure that wiring entries maintain enclosure integrity. CE marking further indicates compliance with applicable international standards.
The ER4X-25N6SB carries CE marking and is designed with a NEMA 4X enclosure classification. These certifications support compliance with European market requirements and provide assurance of enclosure protection suitable for challenging industrial environments. Always verify local electrical codes and installation standards relevant to your facility.
The non-fused design reduces complexity in spare-parts management and maintenance planning, contributing to lower downtime during routine maintenance. Its compact footprint simplifies retrofits and panel upgrades, potentially reducing labor costs and warehouse stocking needs while improving safety and reliability in isolation operations.
