Why Choose the Lovato P1MBUH2PC05 Miniature Circuit Breaker?
The Lovato P1MBUH2PC05 is a two-pole miniature circuit breaker (MCB) designed for dependable branch-circuit protection in industrial electrical panels, machinery and automation systems. Part of the Lovato P1 MB series, this model combines a 5 A rated current with a Curve C tripping characteristic for circuits that may experience moderate inrush currents during normal operation.
The P1MBUH2PC05 is rated for 480Y/277 V AC under UL and provides a 10 kA short-circuit rating under both UL and IEC specifications. Its thermal-magnetic operating principle provides automatic overload and short-circuit protection, while compliance with UL489 supports use in appropriate branch-circuit protection applications.
Occupying two DIN modules, the P1MBUH2PC05 installs on a standard 35 mm DIN rail and accepts IEC conductor sections from 1 to 35 mm². With a wide operating temperature range, IP20 frontal protection and a mechanical endurance of 20,000 cycles, it provides a robust solution for professional industrial installations.
