P1MBUL2PD63 Lovato MCB 2P D63 240V 10kA UL489

Why Choose the Lovato P1MBUL2PD63 Miniature Circuit Breaker?

The Lovato P1MBUL2PD63 is a robust 2-pole miniature circuit breaker (MCB) designed to provide reliable 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 compact DIN rail installation with IEC and UL 489 compliance for machinery, automation and branch circuit protection applications.

This circuit breaker features a D tripping characteristic and a rated current of 63 A, making it particularly suitable for circuits supplying equipment with relatively high starting or inrush currents. Its two-pole configuration provides simultaneous protection and switching of two conductors, while the 10 kA short-circuit rating provides dependable interruption capability under fault conditions.

With a rated operational voltage of 240 V AC under UL ratings, alongside 230/400 V AC under IEC ratings and 125 V DC operation, the P1MBUL2PD63 offers versatile circuit protection for industrial applications. Its two-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 P1MBUL2PD63 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 two-pole configuration, 63 A rating, 10 kA short-circuit capacity and UL 489 compliance, the P1MBUL2PD63 provides dependable protection for machinery, automation panels and industrial electrical distribution systems.

Typical Applications

• Industrial machinery and automation control panels.
• 240 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.
