Introduction

Eaton Bussmann Series two-pole UL Type 4 component surge acceptors are surge protective devices for Type 3 applications. These modular SPDs feature local visual status indication and remote contact signaling. A unique module locking system secures the protection module to the base. Modules can be replaced easily without tools — simply press the release button. Integrated mechanical coding between the base and protection module prevents installation of incorrect replacement modules. The characteristics of these two-pole devices are designed to coordinate with other upstream SPDs in UL 508A applications. UL 1449 4th Edition Type 4 component assemblies help meet UL 508A requirements. Proven MOV and GDT hybrid technology delivers reliable surge protection. The module locking system with module release button enables tool-free, effortless module replacement. Remote signaling on all protection modules makes status monitoring simple and accurate in any monitoring scheme. No upstream overcurrent protection required, simplifying installation and reducing costs. Vibration and shock tested per EN 60068-2 for reliable performance in harsh environments. Three-pole terminal remote contact signaling features a floating changeover contact, usable as normally open or normally closed depending on circuit configuration.
