Eaton Specification Sheet - ER12-030CC3PR
The ER12-030CC3PR is an enclosed rotary disconnect switch designed for reliable, code-compliant isolation in industrial control panels. Feature → Business Impact → Application: Enclosed, NEMA 12-rated enclosure protects internal components from dust and moisture, reducing maintenance intervals and safeguarding personnel during disconnection events; this translates to lower downtime and safer operations in harsh environments such as manufacturing floors and outdoor enclosures. The Class CC fuse configuration enables standardized protection for 30 A circuits, improving short-circuit response and enabling predictable coordination with downstream devices in motor control and feeder circuits. Feature → Business Impact → Application: Three-pole operation ensures simultaneous isolation of all phases, supporting safer service disconnects for 3-phase equipment like conveyors, pumps, and presses, minimizing arcing and reducing commissioning time during panel swaps. The pistol-style red handle enhances visibility and ergonomic operation, enabling technicians to perform fast, confident disconnections with minimal effort, even when wearing PPE. This improves maintenance throughput and reduces human error in high-stress shutdown procedures. Feature → Business Impact → Application: CE Marking and cULus Listing, with UL 98 certification noted, provide strong regulatory alignment for both international and North American projects, easing procurement and warranty considerations. In practice, engineers can deploy ER12-030CC3PR in compliant control systems with confidence, knowing it supports easier installation, safer isolation, and predictable maintenance cycles.

FAQs
For safe, code-compliant installation in 3-phase panels, ensure a dedicated, clear mounting area with proper clearance for the pistol handle, use a compatible enclosure rated for NEMA 12 environments, and verify the fuse configuration is Class CC. Plan for correct wiring of all three poles, maintain adequate torque on terminal connections, and align with CE and cULus requirements for a compliant service disconnect.
The ER12-030CC3PR is CE Marked and cULus Listed, with UL 98 certification noted as in progress. These certifications support global and North American compliance for safety and performance. In practical terms, they facilitate installation in regulated facilities, assist with supplier qualification, and reduce the time spent on third-party verifications during audits or project approvals.
Yes. The device is designed specifically for Class CC fuse configurations, aligning with Bussmann Series protective devices. This compatibility ensures predictable protection coordination, simplifies spare parts sourcing, and supports standardized maintenance practices across facilities using Class CC fuses for 30 A circuits at 600 V.
The pistol-style red handle provides immediate visual identification of the disconnect position and offers ergonomic, one-handed operation for panel maintenance. This reduces operation time, minimizes risk during disconnection, and improves safety compliance when performing routine servicing or emergency shutdowns in busy plant environments.
Expect lower downtime and safer maintenance due to faster, more reliable isolation with a clearly visible red pistol handle and robust NEMA 12 protection. The 600 V, 30 A, three-pole design simplifies circuit protection coordination, reducing spare parts inventory and enabling quicker commissioning. Over time, these factors contribute to reduced maintenance costs and improved system availability.
