The DTK-DR Series of DIN-rail surge protectors are designed to provide point-of-use electrical surge protection for machine control panels and similar applications in commercial and industrial environments. Every model in the family provides a 75,000 Amp surge current rating to ensure powerful protection and a long service life. All units feature a compact, modular design for easy integration within machine control panels, and fast replacement of the protection module when needed. The new DTK-DR models include service assurance features that help alert maintenance and management staff of their current status and to trigger action to maintain continued protection. Each unit includes both a dry contact remote end-of-life indicator to report current status, and a visual LED end-of-life indicator for easy status checks and confirmation of remote alerts. The DR Series currently includes 18 models with different voltage configurations — from 120VAC up to 690VAC — to meet project needs.
