Why Choose the Lovato P1MBUH1PD25 Miniature Circuit Breaker?
The Lovato P1MBUH1PD25 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 P1MBUH series, it combines a 25 A rated current, Type D tripping characteristic and UL 489 compliance for branch-circuit protection applications.
Its D-curve characteristic is suited to compatible circuits where relatively high transient or inrush currents can occur during normal operation. The P1MBUH1PD25 provides a 10 kA short-circuit breaking capacity, supporting dependable protection for industrial machinery, automation equipment and electrical control-panel circuits.
The P1MBUH1PD25 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 standard DIN rail format 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 P1MBUH1PD25 combines a 25 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.
Typical Applications
- Industrial electrical control panels.
- UL 489 branch-circuit protection applications.
- Machine control and automation systems.
- Compatible loads with relatively high starting or inrush currents.
- OEM machinery intended for North American markets.
- Low-voltage industrial distribution assemblies.
