News from NPE's Product Improvement Center: LA-1600 and LA-600 Covers


Spotlighting today in NPE’s PIC is our replacement mechanism cover for the problematic blue-faced LA-600 and LA-1600 circuit breakers. As we all know, this molded blue plastic cover is prone to breakage, cracking and/or other failures and it was later replaced by the gold (yellow zinc plated) steel cover in later versions of this breaker line.



                                                                   Cracked/Broken Plastic Faceplate


Our solution? A hand-made steel cover, painted blue and detailed with our house made labels! Guaranteed not to bend or break with normal use, this one and done solution has become very popular. Simply specify what frame size you need and if the breaker is electrically operated or manually operated and we will ship you a new cover within 24 hours. Quantities are limited so large orders may require additional time, but are well worth the wait.
