States M-25016-G Terminal Block

States M-25016-G is a 16-pole NT/ZWM terminal block from the States 250-series, designed for organized multi-point CT terminations in instrument panels and switchgear. The “M” prefix indicates a white marker strip for engraving, while the “250” digits denote a sliding-link connection (with stainless steel linking screws) as opposed to a fixed straight strap, which is designated by “251.” The trailing “G” identifies this as a current-transformer shorting type block, intended to be used with the 251 straight-strap series only to provide a safe shorting path for CT secondaries during servicing or testing. This block sits within States’ NT/ZWM terminal-block family and follows the standard NT/ZWM mounting footprint described in States catalogs. The NT 250-series arrangement uses an 8-32 stainless steel screw for the sliding-link disconnect, ensuring a robust and repeatable connection path across all 16 poles. Accessory fuse-holders are available for 250- and 600-volt systems, but are separate from the block itself. In practice, the M-25016-G offers a compact, labeled, mulitpole CT termination solution suitable for metering panels, control enclosures, and protective-relay assemblies where CT circuit organization and safe shorting during maintenance are priorities.
