Eaton Specification Sheet - ER12-100CF2PB
The ER12-100CF2PB uses a two-pole enclosed rotary disconnect design to minimize arc exposure and prevent mis-wiring, directly improving operator safety and system reliability in automated lines. Business impact: safer startups and fewer containment breaches during maintenance. Application: motor control centers and machine enclosures where space is tight and accessibility is critical. The CF fuse type compatibility enables seamless integration with Bussmann protection devices, reducing sourcing complexity and inventory costs. Business impact: easier maintenance and faster fault isolation. Application: systems that require coordinated protection with protective devices within standard control panels. The pistol-style handle supports one-handed operation, even in cramped cabinets, reducing operator fatigue and increasing eradication of improper disconnections. Business impact: quicker, safer lockout/tagout cycles and improved uptime. Application: routine maintenance and emergency isolation in process lines and packaging equipment. The 600 V, 100 A rating and NEMA 12 enclosure deliver reliable performance in dusty, dirty, or damp environments. Business impact: long service life, minimized environmental ingress, and compliance with industrial protection standards. Application: harsh factory floors, wash-down zones, and outdoor installations where enclosure integrity matters. This unit’s compact footprint (11.8 in L, 10.8 in H, 9.84 in W) and 6 lb weight simplify installation and retrofits in existing panels, enabling scalable protection without major enclosure redesigns. Business impact: lower installation costs and faster project delivery. Application: retrofits and new builds across machinery, conveyors, and process lines.

FAQs
ER12-100CF2PB installs in a standard control panel footprint with an 11.8 inch depth and a 9.84 by 10.8 inch envelope. Wire both poles using CF-rated contacts, maintain proper clearance, and operate with the pistol handle for one-handed actuation. Verify CE compliance and confirm the NEMA 12 enclosure remains sealed before energizing the circuit.
Yes. The switch uses fuse type CF and is designed to coordinate with Bussmann CF fuses, ensuring consistent protection with Eaton protection devices. When wiring, confirm proper fuse sizing for 100 A and 600 V to maintain enclosure integrity and NEMA 12 protection during operation.
This product is ideal for electrical protection and circuit isolation in control panels, machine tool enclosures, and power distribution assemblies. Its two-pole configuration, pistol handle, and CE/NEMA 12 ratings enable safe, reliable isolation in demanding environments, while simplifying maintenance and reducing panel downtime during fault diagnostics and routine servicing.
The ER12-100CF2PB carries CE marking and a NEMA 12 enclosure rating, providing regulatory compliance and environmental protection. It is rated for 600 V and 100 A, making it suitable for robust industrial control applications that require safe isolation and resistance to dust and moisture in harsh environments.
By delivering fast, reliable isolation with a safe pistol-actuated handle, the ER12-100CF2PB minimizes downtime during maintenance and testing. The rugged enclosure reduces unintended openings, while the 600 V/100 A rating supports scalable power distribution, lowering total cost of ownership through improved safety, quicker commissioning, and fewer unplanned outages.
