NLL7-63 2P AC White
CHNAILE
Product Overview
Ensure optimal electrical safety for your building projects with the CHNAILE NLL7-63 series 2-Pole Plug-in AC Miniature Circuit Breaker (MCB). Specifically engineered for alternating current (AC) systems up to 240/415V with a 50A rating, this breaker provides simultaneous protection for two lines (such as Phase and Neutral, or two Phases). Featuring a standard white flame-retardant housing, it seamlessly integrates into commercial and residential distribution boards. The highly efficient "Plug-in" mounting architecture allows electrical contractors to perform rapid installations and module replacements without the need for extensive rewiring.
