Why Choose the Lovato P1MB3PD16 Miniature Circuit Breaker?
The Lovato P1MB3PD16 is a robust 3-pole miniature circuit breaker (MCB) designed to protect three-phase electrical circuits against overloads and short circuits. As part of the established Lovato P1MB modular circuit protection range, it provides reliable protection for industrial control panels, electrical machinery, commercial distribution systems and OEM equipment.
This miniature circuit breaker combines a 16 A rated current, a D tripping characteristic and a 10 kA short-circuit breaking capacity. Its D curve response accommodates high temporary inrush currents, making the P1MB3PD16 particularly suitable for transformers, motors, solenoids, industrial power supplies and other inductive electrical loads.
The P1MB3PD16 features a compact 3-pole, three-module configuration and mounts securely onto a standard 35 mm DIN rail. Its thermal-magnetic protection mechanism, IP20 frontal protection and compliance with recognised international standards make it a dependable choice for panel builders, electrical engineers and machine manufacturers.

Reliable Protection for High-Inrush Circuits
Miniature circuit breakers automatically disconnect electrical circuits when excessive current is detected. Thermal protection responds to sustained overload conditions, while magnetic protection provides rapid isolation during short circuits, helping safeguard cables, connected equipment and electrical assemblies.
The Lovato P1MB3PD16 uses a D curve characteristic that permits higher temporary starting currents than B or C curve breakers. This helps reduce nuisance tripping when energising transformers, motors, solenoids, industrial power supplies and other equipment with substantial inrush current.
Typical Applications
- Industrial control and automation panels.
- Transformer protection circuits.
- Motor and inductive load circuits.
- Industrial power supplies.
- Solenoids and electromagnetic equipment.
- Machine building and OEM equipment.
