Why Choose the Lovato P1MBUL1PD50 Miniature Circuit Breaker?
The Lovato P1MBUL1PD50 is a compact and reliable 1-pole miniature circuit breaker (MCB) designed to provide overcurrent and short-circuit protection for industrial electrical distribution and control systems. As part of the Lovato P1 MB miniature circuit breaker series, it combines space-efficient DIN rail installation with IEC and UL 489 compliance for machinery, automation and electrical panel applications.
This circuit breaker features a D tripping characteristic and a rated current of 50 A, making it particularly suitable for circuits supplying equipment with relatively high starting or inrush currents. Its single-pole configuration provides compact branch circuit protection, while the 10 kA short-circuit rating provides dependable interruption capability under fault conditions.
With a rated operational voltage of 120 V AC under UL ratings, alongside IEC ratings of 230/400 V AC and a rated DC operational voltage of 60 V DC, the P1MBUL1PD50 offers versatile circuit protection for industrial applications. Its single-module construction mounts directly onto a standard 35 mm DIN rail, allowing straightforward integration into electrical distribution boards, machinery and control cabinets.

Reliable Circuit Protection for Industrial Systems
Miniature circuit breakers such as the Lovato P1MBUL1PD50 protect electrical circuits against excessive current caused by overloads and short circuits. When current exceeds permitted operating conditions, the breaker automatically interrupts the circuit to help protect conductors, connected equipment and the wider electrical installation.
The D tripping characteristic is particularly useful in industrial circuits where short-duration starting currents can be considerably higher than normal operating current. Combined with its 50 A rating, 10 kA short-circuit capacity and UL 489 compliance, the P1MBUL1PD50 provides dependable protection for machinery, automation panels and industrial electrical distribution systems.
Typical Applications
- Industrial machinery and automation control panels.
- 120 V AC branch circuit protection.
- Motor and inductive-load circuits with elevated starting currents.
- Manufacturing and production equipment.
- OEM machinery and electrical control cabinets.
- Industrial power distribution systems.
