Why Choose the Lovato P1MBUH1PD20 Miniature Circuit Breaker?
The Lovato P1MBUH1PD20 is a compact single-pole miniature circuit breaker (MCB) designed to provide overload and short-circuit protection in industrial control and electrical distribution applications. Part of the Lovato P1MB series, it combines a 20 A rated current, Type D tripping characteristic and UL 489 compliance for applications requiring branch-circuit protection.
Its D-curve characteristic is suited to compatible circuits where relatively high transient or inrush currents can occur during normal operation. The P1MBUH1PD20 provides a 10 kA short-circuit breaking capacity, supporting dependable protection for industrial machinery, automation equipment and control-panel circuits.
The P1MBUH1PD20 is rated at 277 V AC and operates at 50/60 Hz. Its compact 1-module construction, IP20 protection, conductor capacity from 1–35 mm² and DIN rail mounting make it straightforward to integrate into professional industrial electrical assemblies.

Reliable D-Curve Protection for Industrial Equipment
Miniature circuit breakers automatically interrupt electrical circuits when overload or short-circuit conditions occur, helping protect conductors and connected equipment against excessive current. A D-curve breaker provides a higher instantaneous magnetic trip threshold than B- or C-curve devices, making this characteristic appropriate for selected loads that can produce relatively high starting or energisation currents.
The Lovato P1MBUH1PD20 combines a 20 A rating, D-curve characteristic, 277 V AC rating and 10 kA breaking capacity in a compact single-module device. Its UL 489 compliance makes it particularly suitable for industrial machinery and electrical panels requiring recognised branch-circuit protection for North American installations.
