Why Choose the Lovato P1MBUH3PD01V6 Miniature Circuit Breaker?
The Lovato P1MBUH3PD01V6 is a compact three-pole miniature circuit breaker (MCB) designed to provide thermal-magnetic overload and short-circuit protection in industrial electrical distribution and control systems. Part of the Lovato P1 MB range, it combines a 1.6 A rated current with Curve D tripping characteristics and IEC / UL489 compliance for dependable circuit protection.
The P1MBUH3PD01V6 is rated at 480Y/277 V AC under UL and 230/400 V AC under IEC, with a 10 kA short-circuit rating under both standards. Its three-pole construction occupies three DIN modules, providing coordinated protection across three conductors in a compact format suitable for machinery, automation systems, OEM equipment and industrial control panels.
A Curve D tripping characteristic provides increased tolerance of high transient starting currents, making this breaker particularly suitable for compatible transformers, power supplies, solenoids and other inductive loads. Its wide -40 to +70 °C operating temperature range, 35 mm DIN rail mounting and terminals accepting conductors up to 35 mm² make the P1MBUH3PD01V6 a versatile choice for demanding industrial installations.

Three-Pole Curve D Protection for High-Inrush Loads
The Lovato P1MBUH3PD01V6 uses a thermal-magnetic operating mechanism to protect electrical circuits against sustained overloads and short circuits. The thermal element responds to prolonged excessive current, while the magnetic element provides rapid interruption during severe fault conditions, helping protect conductors and connected electrical equipment.
Its Curve D characteristic provides increased tolerance of high transient starting currents, making the P1MBUH3PD01V6 particularly useful for compatible inductive and high-inrush equipment. Combined with its 1.6 A current rating, three-pole construction, 480Y/277 V AC UL operational voltage and 10 kA short-circuit rating, it provides robust protection for low-current industrial circuits where three-pole switching and protection are required.
Typical Applications
- Industrial electrical control and distribution panels.
- UL489 branch circuit protection.
- 480Y/277 V AC industrial electrical systems.
- Industrial machinery and automation equipment.
- Compatible transformers, power supplies, solenoids and inductive loads with high inrush currents.
